FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with kidney stones is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about kidney stones, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to kidney stones, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on kidney stones. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to kidney stones, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on kidney stones. The Editors

CHAPTER 1. STUDIES ON KIDNEY STONES Overview In this chapter, we will show you how to locate peer-reviewed references and studies on kidney stones.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and kidney stones, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “kidney stones” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: ·
Stressful Life Events and Risk of Symptomatic Kidney Stones Source: International Journal of Epidemiology. 26(5): 1017-1023. October 1997. Contact: Available from Oxford University Press. Journals Subscription Department, Great Clarendon Street, Oxford OX2 6DP, UK. 44 (0)1865 267907. Fax 44 (0)1865 267485. Summary: A substantial proportion of cases of hypercalciuria (extra calcium in the urine) and nephrolithiasis (kidney stones) are idiopathic (undetermined cause). Several studies suggest that stressful life events increase lithogenic urinary constituents (calcium, oxalate, and uric acid). This article reports on a study undertaken to test the hypothesis that there is an association between stressful life events and symptomatic kidney stones. The case control study of 200 symptomatic kidney stone cases and 200 matched controls was designed. In this study, the stressors included those life events

Kidney Stones
that the subjects perceived as highly stressful and inflicted upon them in an intense emotional impact with apprehension and distress for at least one week in duration. Ten of eleven (92 percent) categories and 41 of 60 (68 percent) subcategories of stressful events occurred more frequently among cases than controls. Eighteen stressful events had odds ratios of 1.5 or greater. Of the seven significant variables that were entered into a multivariate logistic regression model, the following three remained statistically significant between cases and controls: annual family income (lower for cases); stressful mortgage problems; and emotional life events. The overall prevalence rate of stressful life events was significantly higher among cases than controls. The authors conclude that the data support the hypothesis that there is an association between stressful life events and symptomatic kidney stones. Stress has already been implicated as an important factor in coronary heart disease and a variety of other illnesses. If the results of this preliminary study are confirmed, it would add another disease to the list of those influenced by stress and provide more compelling reasons to include stress detection and management as one component of regular health promotion and disease prevention examinations. 2 tables. 23 references. ·
Kidney Stones: Identifying the Causes Source: Patient Care. 24(15): 31-36, 39-40, 43-46. September 30, 1990. Summary: Advances in understanding the pathophysiology of kidney stone formation have paved the way for efficient metabolic evaluation, which in turn guides the design of an effective preventive regimen. So contend the authors of this article which focuses on identifying the causes of kidney stones. The authors stress that advances in acute treatment of renal calculi should not lead to neglect of metabolic evaluation and preventive treatment. Other topics discussed include hypercalciuria, systemic diseases associated with hypercalciuria, types of idiopathic hypercalciuria, noncalcium stones, metabolic evaluation of both first-time and recurrent stone patients, metabolic abnormalities in nephrolithiasis, and simplified metabolic evaluation available by mail. 1 figure. 1 table. 13 references.

Beverage Use and Risk for Kidney Stones in Women Source: Annals of Internal Medicine. 128(7): 534-540. April 1, 1998. Summary: An increase in fluid intake is routinely recommended for patients who have had kidney stones to decrease the likelihood of recurrence. However, data on the effect of particular beverages on stone formation in women are limited. This article reports on a study undertaken to examine the association between the intake of 17 beverages and risk for kidney stones in women. The prospective cohort study included 8 years of followup. The participants were 81,093 women in the Nurses Health Study who were 40 to 65 years of age in 1986 and had no history of kidney stones. Beverage use and diet were assessed in 1986 and 1990 with validated, self-administered food frequency questionnaire. The main outcome measure was incident symptomatic kidney stones. During 553,081 person-years of followup over the 8 year period, 719 cases of kidney stones were documented. After risk factors other than fluid intake were controlled for, the relative risk for stone formation for women in the highest quintile of total fluid intake compared with women in the lowest quintile was 0.62. Inclusion of consumption of specific beverages in the multivariate model significantly added to prediction of risk for kidney stones. In a model that adjusted simultaneously for the 17 beverages and other possible risk factors, risk for stone formation decreased by the following amount for each 8 ounce serving consumed daily: 10 percent for caffeinated coffee, 9 percent for decaffeinated coffee, 8 percent for tea, and 59 percent for wine. In contrast, a 44 percent
Studies

increase in risk was seen for each 8 ounce serving of grapefruit juice consumed daily. The authors note that the observed protective effect of caffeinated coffee, tea, and alcoholic beverages may be mediated through their effect on urinary concentration. Caffeine increases flow of a more dilute urine by interfering with the action of antidiuretic hormone on the distal nephron, thus decreasing risk for crystal formation. However, this beneficial effect may be partly offset by the increase in urinary calcium excretion caused by caffeine. The authors conclude that an increase in total fluid intake can reduce risk for kidney stones, and the choice of beverage may be meaningful. 3 tables. 32 references. (AA-M). ·
Comparison of Dietary Calcium with Supplemental Calcium and Other Nutrients as Factors Affecting the Risk for Kidney Stones in Women Source: Annals of Internal Medicine. 126(7): 497-504. April 1, 1997. Contact: Available from American College of Physicians. American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Website: www.acponline.org. Summary: Calcium intake is believed to play an important role in the formation of kidney stones, but data on the risk factors for stone formation in women are limited. This article reports on a study undertaken to examine the association between intake of dietary and supplemental calcium and the risk for kidney stones in women. The prospective cohort study with 12 year followup included 91,731 women participating in the Nurses' Health Study I who were 34 to 59 years of age in 1980 and had no history of kidney stones. Self administered food frequency questionnaires were used to assess diet in 1980, 1984, 1986, and 1990. The main outcome measure was incident symptomatic kidney stones. During 903,849 person years of followup, 864 cases of kidney stones were documented. After adjustment for potential risk factors, intake of dietary calcium was inversely associated with risk for kidney stones and intake of supplemental calcium was positively associated with risk. The relative risk in women who took supplemental calcium compared with women who did not was 1.20. In 67 percent of women who took supplemental calcium, the calcium either was not consumed with a meal or was consumed with meals whose oxalate content was probably low. The authors conclude that high intake of dietary calcium appears to decrease risk for symptomatic kidney stones, whereas intake of supplemental calcium may increase risk. Because dietary calcium reduces the absorption of oxalate, the apparently different effects caused by the type of calcium may be associated with the timing of calcium ingestion relative to the amount of oxalate consumed. However, other factors present in dairy products (the major source of dietary calcium) could be responsible for the decreased risk seen with dietary calcium. 6 tables. 33 references.

[email protected]. Summary: Currently, only struvite stones are regarded as deriving from bacteria. Recent work has suggested that calcium based stones might also have an infectious origin. This article reviews related research and discusses the potential role of bacteria in the development of kidney stones. Nanobacteria, small intracellular bacteria found in human kidney stones, are capable of forming a calcium phosphate shell, and thus could serve as crystallization centers for renal calculi (stone) formation. Until now, however,

all trials performed to confirm the presence of nanobacteria in human calculi, serum, or urine have failed. The authors note that if any other bacteria are to be implicated in the development of renal stones, the best way to identify them would be to screen more randomly for expression of nonhuman DNA or RNA in stone forming kidneys. 10 references. ·
Modification of Dietary Oxalate and Calcium Reduces Urinary Oxalate in Hyperoxaluric Patients with Kidney Stones Source: Journal of the American Dietetic Association. 93(11): 1305-1307. November 1993. Summary: Dietary restriction of oxalate intake has been used to reduce the risk of recurrence of calcium oxalate kidney stones. This article reports on a research study that entailed modification of dietary oxalate and calcium. Seventeen patients who experienced hyperoxaluria when consuming their usual diets were identified from patients with kidney stones who were referred for clinical studies. Thirteen of these patients volunteered for the study: six women aged 35 to 63 years and seven men aged 37 to 49 years. The study consisted of three diets: Diet A, a low-calcium diet; Diet B, which omitted eight high-oxalate foods and included 300-mg calcium per day; and Diet C, in which patients ate any high-oxalate foods they preferred. Results showed that urinary oxalate was significantly lower in patients when they consumed diets A and B than when they consumed diet C. Urinary calcium excretion was not significantly different among dietary treatments. 1 figure. 1 table. 12 references.

100. Diet and Kidney Stones Source: New England Journal of Medicine. 346(2): 74-76. January 10, 2002. Summary: Kidney and bladder stones cause excruciating pain, tend to recur, and are distressingly common. This article briefly summarizes the history of medical understanding and treatment of kidney stones, reviews the dietary approaches to management and prevention, and offers an introduction to a related article elsewhere in the same journal. The author notes that the research study found that the participants (all male) assigned to a normal calcium diet (but low in animal protein and salt) had far fewer stones recurring than did men assigned to a low calcium diet. The author concludes that, while this approach has yet to be proven in men and women, or in a wider geographic area than in the original study, it may be worthwhile to try in a patient at risk of kidney or bladder stone recurrence. 1 figure.

New Treatment Options for Kidney Stones Source: Family Urology. 6(2): 4-6. 2001. Contact: Available from American Foundation for Urologic Disease. 1126 North Charles Street, Baltimore, MD 21201. (800) 242-2383 or (410) 468-1800. Fax (410) 468-1808. Website: www.afud.org. Summary: Kidney stones (lithiasis) are formed by various crystals that gather in the kidneys or urinary tract. These materials build up over a period of time and ultimately interfere with urination. This article reviews new treatment options for kidney stones. Research has shown that shock waves generated outside the body can pulverize urinary stones inside the body, resulting in spontaneous passage of sand like particles. This treatment, called lithotripsy, is preferred to traditional surgical treatment in most cases. Approximately 50 to 80 percent of patients treated with lithotripsy become stone free, depending on the size and type of stone treated. Most of the remaining patients pass the

majority of their stone(s) but are left with some residual stone fragments that cause no symptoms. Some patients (approximately 10 to 30 percent) require more than one lithotripsy treatment to completely pulverize their stone(s). The authors describe what the patient can expect during a lithotripsy treatment, which usually lasts approximately one hour. The authors then describe the use of ureteroscopy, a procedure which is often used to remove stones in the ureter and the kidney. Ureteroscopy uses a small flexible guide wire, small fiberoptic scopes, and laser or ultrasound devices to locate, fragment, and remove the stone(s). A final option for removal of kidney stones is discussed: percutaneous (PERC) nephrostolithotomy, which is used to treat extremely large kidney stones, difficult to fragment stones, patients with a blockage in the urinary tract as well as kidney stones, or patients in whom shock wave lithotripsy has not been successful. Depending on the type of kidney stone problem treated, antibiotics are commonly prescribed for a week or two following discharge from the hospital. ·
Family History and Risk of Kidney Stones Source: JASN. Journal of the American Society of Nephrology. 8(10): 1568-1573. October 1997. Contact: Available from Williams and Wilkins. 428 E. Preston Street, Baltimore, MD 21202. (800) 638-6423. Summary: Kidney stones develop more frequently in individuals with a family history of kidney stones than in those without a family history; however, little information is available regarding whether the increased risk is attributable to genetic factors, environmental exposures, or some combination. In this article, the authors report on a study in which the relation between family history and risk of kidney stone formation was investigated in a cohort of 37,999 male participants in the Health Professionals Follow-up Study. Information on family history, kidney stone formation, and other exposures of interest, including dietary intake, was obtained by mailed questionnaires. A family history of kidney stones was much more common in men with a personal history of stones at baseline in 1986 than in those without a history of stones. During 8 years of followup, 795 incident cases of stones were documented. After adjusting for a variety of risk factors, the relative risk of incident stone formation in men with a positive family history, compared with those without, was 2.57. Family history did not modify the inverse association between dietary calcium intake and the risk of stone formation. These results suggest that a family history of kidney stones substantially increases the risk of stone formation. In addition, the data suggest that dietary calcium restriction may increase the risk of stone formation among individuals with or without a family history of kidney stones. Despite the strong association between family history and kidney stones, most individuals who have kidney stones do not have a family history of stones. 5 tables. 21 references. (AA-M).

Randomized Controlled Trial of a Low Animal Protein, High Fiber Diet in the Prevention of Recurrent Calcium Oxalate Kidney Stones Source: American Journal of Epidemiology. 144(1): 25-33. July 1, 1996. Summary: Low protein diets are commonly prescribed for patients with idiopathic calcium nephrolithiasis, who account for more than 80 percent of new diagnoses of kidney stones. This dietary advice is supported by metabolic studies and epidemiologic observational studies but has not been evaluated in a controlled trial. This article reports on a study in which the authors, using 1983 to 1985 data from three Northern California Kaiser Permanente Medical Centers, randomly assigned 99 persons who had calcium

oxalate stones for the first time to a low animal protein, high fiber diet. The diet contained approximately 56 to 64 g daily of protein, 75 mg daily of purine (primarily from animal protein and legumes), one-fourth cup of wheat bran supplement, and fruits and vegetables. Intervention subjects were also instructed to drink six to eight glasses of liquid daily and to maintain adequate calcium intake from dairy products or calcium supplements. Control subjects were instructed only on fluid intake and adequate calcium intake. Both groups were followed regularly for up to 4.5 years with food frequency questionnaires, serum and urine chemistry analysis, and abdominal radiography; and they were urged to comply with dietary instructions. In the intervention group of 50 subjects, stones recurred in 12 (7.1 per 100 person-years) compared with 2 (1.2 per 100 person-years) in the control group; both groups received a mean of 3.4 person-years of followup. After adjustment for possible confounding effects of age, sex, education, and baseline protein and fluid intake, the relative risk of a recurrent stone in the intervention group was 5.6 compared with the control group. The authors conclude that advice to follow a low animal protein, high fiber, high fluid diet has no advantage over advice to increase fluid intake alone. 3 figures. 4 tables. 40 references. (AA-M). ·
Nanobacteria: An Infectious Cause for Kidney Stone Formation Source: Kidney International. 56(5): 1893-1898. November 1999. Contact: Available from Blackwell Science, Inc. Journals Fulfillment Department, 350 Main Street, Malden MA 02148. (781) 388-8250. Summary: Nanobacteria are cytotoxic, sterile filterable, gram negative, atypical bacteria detected in bovine (cow) and human blood. Nanobacteria produce carbonate apatite on their cell walls. Data on Randall's plaques suggest that apatite may initiate kidney stone formation. This article reports on a study that assessed nanobacteria in 72 consecutively collected kidney stones from Finnish patients. Nanobacteria and kidney stone units were compared using scanning electron microscopy (SEM). Demineralized kidney stones were screened for nanobacteria. SEM highlighted the resemblance in size and morphology of nanobacteria and the smallest apatite units in the kidney stones. Nanobacterial antigens could be detected after the demineralization of the stones (with hydrogen chloride). Nanobacteria were surprisingly resistant to this treatment, and cultures could be established from 93.1 percent of the stones. Only struvite stones had common bacteria, in addition to the nanobacteria. When the results of all of the assays were combined, 70 of the 72 stones (that is, 97.2 percent) were nanobacteria positive. Although apatite stones indicated highest nanobacteria antigen signals, the overall nanobacteria positivity did not depend on the stone type. The isolated nanobacteria produced apatite stones in vitro. The authors propose that kidney stone formation is a nanobacterial disease analogous to Helicobacter pylori infection and peptic ulcer disease. Both diseases are initiated by bacterial infection and subsequently endogenous and dietary factors influence their progression. 3 figures. 1 table. 29 references.

Prospective Study of Beverage Use and the Risk of Kidney Stones Source: American Journal of Epidemiology. 143(3): 240-247. February 1, 1996. Summary: Patients with kidney stones are routinely advised to increase their fluid intake to decrease the risk of stone recurrence. However, there has been no detailed examination to determine whether the effect on recurrence varies by the type of beverages consumed. In this article, the authors report on their prospective study of the relation between the intake of 21 different beverages and the risk of symptomatic kidney

stones in a cohort of 45, 289 men, 40 to 75 years of age, who had no history of kidney stones. During 6 years of followup, 753 incident cases of kidney stones were documented. After adjusting for other variables, consumption of specific beverages significantly added to the prediction of kidney stone risk. The risk of stone formation decreased by the following amount for each 240ml (8 oz) serving consumed daily: caffeinated coffee, 10 percent; decaffeinated coffee, 10 percent; tea, 14 percent; beer, 21 percent; and wine, 39 percent.

Contact: McGraw-Hill Healthcare Publications. 4530 West 77th Street, Minneapolis, MN 55435. (612) 835-3222. Fax (615) 835-3460. Summary: Recent findings have provided insight into the molecular basis of kidney stone formation and entirely changed the approach to management of calcium stones. This article reviews these new insights into the causes and treatments of kidney stones. Medical therapy for the underlying causes of kidney stones, such as the use of thiazides for hypercalciuria (too much calcium in the urine), potassium citrate for hypocitraturia (too little citrate in the urine), or allopurinol for hyperuricosuria (too much uric acid in the urine), will reduce the rate of stone recurrence. Increased water intake will also reduce the frequency of recurrences, as has been demonstrated in a randomized prospective trial. Rational dietary therapy is also beneficial. The author stresses that the financial benefits of reducing stone recurrence far outweigh the costs of diagnostic evaluation and therapy. All patients with recurrent stones should have a full metabolic evaluation. For those who do not respond to medical treatment, new surgical techniques, including extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy, ureteroscopy, and laser lithotripsy, are improvements over older surgical options for this painful disease. The author concludes that understanding the role of genetic factors and the various promotors and inhibitors of stone formation should lead to more effective prophylaxis and treatment of other types of stones as well. 3 figures. 2 tables. 12 references.

Effects of 5 Different Diets on Urinary Risk Factors for Calcium Oxalate Kidney Stone Formation: Evidence of Different Renal Handling Mechanisms in Different Race Groups Source: Journal of Urology. 168(3): 931-936. September 2002. Contact: Available from Lippincott Williams and Wilkins. 12107 Insurance Way, Hagerstown, MD 21740. (800) 638-3030 or (301) 714-2334. Fax (301) 824-7290. Summary: Since the incidence of renal calculi (kidney stones) in the South African black population is extremely rare while in white subjects it occurs at the same rate as elsewhere in the western world, the authors of this article investigated the possibility that different renal (kidney) handling mechanisms in response to different dietary challenges might occur in the 2 race groups. The authors report on a study in which they administered 5 different dietary protocols, including low calcium, high oxalate, vitamin C, high salt and lacto-vegetarian, to 10 healthy male subjects from each race group. The low calcium diet caused statistically significant changes only in black subjects, which consisted of urinary oxalate increase, relative supersaturation of calcium oxalate decrease, and relative supersaturation of brushite increase. The high oxalate diet caused

statistically significant changes in both race groups, but these changes were different in the 2 groups. Clinically unimportant changes occurred in both race groups after the other 3 diets. The authors conclude that renal handling of dietary calcium and oxalate in South African black and white subjects is different and may explain the different stone incidence in the 2 race groups. 6 tables. 32 references. ·

Contact: Available from American Academy of Family Physicians. 11400 Tomahawk Creek Parkway, Leawood, KS 66211-2672. (800) 274-2237. Website: www.aafp.org. Summary: This article discusses the diagnosis and initial management of urinary stones (urolithiasis), which have undergone considerable evolution in recent years. The application of nonconstrast helical computed tomography (CT scan) in patients with suspected renal colic (kidney pain) is one major advance. The superior sensitivity and specificity of helical CT allow urolithiasis to be diagnosed or excluded definitively and expeditiously without the potential harmful effects of contrast media. Initial management is based on three key concepts: the recognition of urgent and emergency requirements for urologic consultation, the provision of effective pain control using a combination of narcotics and nonsteroidal antiinflammatory drugs (NSAIDs) in appropriate patients, and an understanding of the impact of stone location and size on natural history and definitive urologic management. The authors discuss these concepts with reference to contemporary literature, with the goal of providing tools that family physicians can use in the emergency department or clinic. A patient care algorithm is also provided. 2 figures. 5 tables. 32 references.

Prospective Study of Dietary Calcium and Other Nutrients and the Risk of Symptomatic Kidney Stones Source: New England Journal of Medicine. 328(12): 833-838. March 25, 1993. Summary: This article reports on a prospective study conducted on the relation between dietary calcium intake and the risk of symptomatic kidney stones in a cohort of 45,619 men, 40 to 75 years of age, who had no history of kidney stones. Dietary calcium was measured by means of a semiquantitative food-frequency questionnaire in 1988. During four years of follow-up, 505 cases of kidney stones were documented. Results show that, after adjustment for age, dietary calcium intake was inversely associated with the risk of kidney stones. Other potential risk factors discussed include alcohol consumption and dietary intake of animal protein, potassium, and fluid. The authors conclude that a high dietary calcium intake decreases the risk of symptomatic kidney stones. 5 tables. 40 references. (AA-M).

Combination 'Sandwich' Therapy for Extensive Renal Calculi in 100 Consecutive Patients: Immediate, Long-Term and Stratified Results from a 10-Year Experience Source: Journal of Urology. 158(2): 342-345. August 1997. Summary: This article reports on a study that investigated the immediate and long term efficacy of combination 'sandwich' therapy for the management of large, extensively branched renal calculi (kidney stones) in 100 consecutively treated patients. 61 women and 39 men were treated for stones ranging from 2.2 to 66 cm (mean size 20.8 cm) with percutaneous debulking (with a nephroscope and ultrasound) followed by shock wave lithotripsy and, when necessary, secondary nephroscopy via the mature tract. The primary debulking was performed via 1 to 3 tracts, following which 1 to 3 shock wave treatments were administered. Subsequently, 62 patients underwent 71 secondary or tertiary percutaneous procedures. The total hospital stay ranged from 3 to 44 nights (mean 12.2 nights) and decreased with experience. In 34 patients, 40 complications developed, the most frequent of which were bleeding requiring transfusion (14 patients) and fever or sepsis delaying a planned procedure or hospital discharge (20 patients). For patients with struvite stones, the transfusion rate and fever sepsis rate were 20 and 33 percent, respectively, compared to only 10 and 12 percent, respectively, for those patients with noninfection related stones. Of 87 patients available for 1-month radiographic followup, 55 (63 percent) were stone-free, while 32 (37 percent) had discrete residual gravel. With time and experience, the stone free rate improved from 52 to 70 percent. Of 55 patients followed for a mean of 40.5 months, ipsilateral stones recurred in 13 (22.8 percent). Of 39 patients with struvite calculi, 11 (28 percent) had recurrent bacteriuria or infection. The authors conclude that this combined sandwich approach offers immediate and long-term results comparable to other forms of management currently available for these challenging cases. Furthermore, this approach may be applied successfully to virtually any patient with large, extensively branched, or otherwise complex stones. 1 figure. 3 tables. 19 references. (AA-M).

Summary: This article reports on a study undertaken to determine the effect of substituting equal amounts of dietary protein as animal protein (beef) for plant protein (legumes, seeds, nuts, and grains) on urinary components associated with calcium oxalate precipitability risk (which can lead to kidney stones made of calcium). The randomized crossover trial included 23 patients with normal levels of calcium in their urine who had a history of calcium kidney stones (8 women and 15 men, mean age 50.7 years plus or minus 14.6 years). The study included a 4 day, free living adaptation period, followed by a 2 day metabolic unit study. The study compared consumption of two servings of beef (43 g protein for women and 50 g for men) daily with an equal amount of protein from plant foods including legumes, nuts, and grains. Urinary calcium, oxalate, magnesium, citrate, phosphorus, volume, and Tiselius risk index (TRI) did not differ between diets. Urinary sodium and potassium were higher for patients on the plant protein diet. After correcting for variations in urinary sodium and potassium between diets, the difference in urinary calcium remained insignificant. The authors conclude that balanced diets containing moderate amounts of either beef or plant protein are equally effective in reducing calcium oxalate kidney stone risk based on changes in urinary composition. 4 tables. 27 references. ·

Contact: Available from Mayo Foundation for Medical Education and Research. 200 First Street SW, Rochester, MN 55905. Summary: This brief article reviews the problem of kidney stones and offers suggestions for determining whether they require medical intervention. The article summarizes recommendations from a panel convened by the American Urological Association that can help a physician determine whether a patient's stones are the 'wait and see' type or need to be removed immediately. The article reviews the problem of kidney stones, which can be caused by heredity, diet, low fluid intake, and certain diseases, and which can cause bleeding, inflammation, infection, and severe pain. About 90 percent of kidney stones are small enough to pass through the urinary system on their own; however, this process can be extremely painful. Stones that pass into the ureter, are larger than one-half inch in diameter, or that cause obstruction should be removed by lithotripsy or ureteroscopy. The article concludes by emphasizing that the most important treatment and prevention strategy is to increase the amount of water that the patient drinks each day. The author recommends that everyone should drink enough fluid to produce approximately 2 quarts of urine per day. 1 figure.

Project Title: A NOVEL PREDICTOR OF NEPHROLITHIASIS Principal Investigator & Institution: Bergsland, Kristin J.; Litholink Corporation 2250 W Campbell Park Dr Chicago, IL 60612 Timing: Fiscal Year 2003; Project Start 01-MAY-2003; Project End 31-OCT-2003 Summary: (provided by applicant): The overall scientific and commercial objective of the proposed research is to develop a clinical assay that can predict the recurrence of kidney stones in patients with nephrolithiasis. Since currently available diagnostic tools cannot predict who will develop recurrent kidney stones, those destined to recur would benefit from tests that could identify them in advance. We propose to develop western blotting and ELISA methods to measure various forms of a urine protein that is a known inhibitor of calcium oxalate crystallization. Preliminary studies have shown that measurement of one form of this protein combined with standard stone risk chemistries improves the sensitivity of detection of stone formers compared with stone risk chemistries alone. We will perform the assays on urine from a random sample of 50 stone formers and 50 non-stone formers. We will identify the assay(s) that best discriminate stone formers from non-stone formers, either when used alone or combined with standard stone risk chemistries. In Phase II we will prospectively test whether these measurements can identify kidney stone patients at risk for recurrence. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: ANGIOTENSIN ELIMINATION
II
REGULATION
OF
ENTERIC
OXALATE
Principal Investigator & Institution: Hatch, Marguerite; Associate Professor; Pediatrics; Northwestern University Office of Sponsored Programs Chicago, IL 60611 Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-MAY-2001 Summary: Approximately one million cases of stone diseases are diagnosed in the United States every year. Most kidney stones (80%) are comprised of calcium oxalate and a major risk factor in this disease is elevated urinary oxalate excretion. The broad aims are to investigate and enhance elimination of oxalate into the large intestine where it can be innocuously degraded by the substrate-specific bacteria (Oxalobacter sp.) which reside exclusively in this segment of the alimentary tract. The specific aims of this proposal focus on the signals involved in shifting the balance from renal to enteric oxalate elimination and on the modulation of this colonic oxalate secretion and excretion. Three key pieces of information have emerged from our recent studies of colonic oxalate transport in rats with chronic renal failure (CRF). 1). The large intestine is the primary site for the CRF-induced adaptation where basal oxalate absorption is reversed to a secretory flux inhibitable by angiotensin II (ANG II, subtype AT1) receptor antagonists. 2). In CRF rat intestine, AT1 receptors are up-regulated exclusively in the large intestinal segment. 3). The effects of AT1 receptor agonism and antagonism on oxalate transport in the CRF rat can be simulated in vitro in a control rat which normally supports a basal absorptive flux of oxalate. Together, these observations imply that ANG II plays a role in local modulation of colonic oxalate secretion. The working hypothesis to be tested is that the balance between renal and enteric oxalate elimination is modulated by an up- regulation in colonic AT1 receptors. The research plan is divided into two interrelated parts and involves using a cultured cell model along with a variety of animal models created in an effort to simulate human hyperoxaluric/hyperoxalemic conditions. Pr I is aimed at examining the signals involve din initiating the local upregulation of colonic T1 receptors in oxalate secreting colonic tissues. In Part II, the signaling transduction pathways involved in coupling AT1 receptor agonism to the transport systems initiating oxalate secretion will be addressed. The outcome of the propose studies will provide a significant advance in our fundamental understanding of adaptations in oxalate handling in kidney disease. The potential for oxalate excretion into the lumen of the large intestine, where it can be degraded by Oxalobacter enzymes, provides for a "sump" mechanism which, is exploited, could have significant impact on reducing hyperoxalemia, hyperoxaluria, oxalosis, and the resulting various pathophysiological and debilitating conditions.

Project Title: BINDING OF CALCIUM CRYSTALS WITH RENAL CELLS Principal Investigator & Institution: Toback, F. Gary. Professor of Medicine and Cell Biology; University of Chicago 5801 S Ellis Ave Chicago, IL 60637 Timing: Fiscal Year 2001 Summary: Although nephrolithiasis is a common condition, the sequence of events by which crystals are retained in the kidney and form stones is poorly understood. Therefore, additional knowledge is required to identify susceptible patients and formulate new therapeutic strategies to prevent kidney stones which cause pain, hematuria, urinary tract obstruction and infection, and to eliminate the need for expensive procedures such as extracorporeal shock wave lithotripsy or surgery. Our previous studies demonstrate that calcium oxalate monohydrate (COM) crystals bind
Studies 15
within seconds to anionic, sialic acid-containing glycoproteins on the apical surface of kidney epithelial cells in culture (employed to model the tubule), suggesting one mechanism whereby crystals could be retained in the kidney. Identification of those molecules on the renal cell surface that mediate crystal binding, and how their expression is modulated, will greatly increase insight into the pathogenesis of nephrolithiasis. Our Preliminary Studies provide evidence that the capacity of renal cells to bind COM crystals is not static, but is regulated by exogenous prostaglandin E (PGE) and intracellular cyclic AMP. Additionally, our recent work utilizing a novel experimental protocol, crystal-affinity chromatography, provides new information about the nature of receptors on the surface of cultured renal cells that bind calcium oxalate crystals, including one apparently novel Cell Surface Protein (CSP) that has been isolated and partially sequenced. Our Specific Aims are to: 1) Define mechanisms by which PGE modulates renal cell crystal affinity by investigating its effect on adhesion of hydroxyapatite (HA) crystals to cells, and its role during crystal adhesion to wounded monolayers; study PGE release in response to renal cell-crystal interactions; study regulation of intracellular cAMP in response to PGE; define the effect of PGE on renal cell protein and glycoprotein synthesis; and define the expression of specific crystal receptor proteins after exposure to PGE. 2) Identify and characterize renal epithelial cell surface glycoprotein receptor(s) for COM and HA crystals; obtain a full-length cDNA clone encoding an apparently novel CSP COM crystal receptor; study regulation of CSP expression in renal cells; define CSP gene and protein distribution in renal and nonrenal tissues; and characterize cell surface receptors for other urinary crystals, and in different types of cells. The results will provide new understanding of the mechanisms that control adhesion of urinary crystals to the surface of kidney epithelial cells.

Project Title: CHARACTERIZATION OF THE REGULATORY PROTEIN, URER Principal Investigator & Institution: Dattelbaum, Jonathan D. Microbiology and Immunology; University of Maryland Balt Prof School Baltimore, MD 21201 Timing: Fiscal Year 2002; Project Start 01-MAR-2002 Summary: (provided by the applicant): Urinary tract infections (UTIs) are one of the most frequently diagnosed kidney and urological disorders. While Proteus mirabilis is responsible for only a few percent of all UTIs, individuals with anatomical abnormalities or long-term indwelling medical devices are highly susceptible to P. mirabilis bladder and kidney infections. A hallmark of P. mirabilis UTI is the formation of bladder and kidney stones due to the urea-induced activity of urease. Ammonia formed by the urease-catalyzed breakdown of urea increases local pH resulting in crystallization of magnesium and calcium metal salts. Urease statement is regulated by UreR, a member of the AraC family of transcriptional regulators. UreR DNA-binding properties and transcriptional activity have been partially characterized. We hypothesize that urea binds directly to UreR resulting in a conformational change in the protein which alters its interaction DNA. Purified recombinant UreR will be used to study the effect of urea and DNA on UreR dimerization. Equilibrium dialysis will be used to measure the urea binding constant for UreR. In the absence of urea, we hypothesize that UreR stimulates DNA looping which shuts off transcription of urease. The ability of UreR to induce bends in DNA will be evaluated using circular permutation analysis. Further work will be performed using DNA minicircles containing UreR binding sites. We will determine if an inverted UreR dimer is formed in the presence and absence of urea. This research will be used to develop a model for the UreR-mediated transcription regulation of the urease operon.

Project Title: DEVELOPMENT OF A UREA BIOSENSOR USING THE URER PROTEIN Principal Investigator & Institution: Mobley, Harry L. Professor; Microbiology and Immunology; University of Maryland Balt Prof School Baltimore, MD 21201 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2005 Summary: (provided by applicant): Individuals in the U.S. with kidney conditions including infection, kidney stones, cancer, or missing kidney exceed 2.5 million annually. Most renal diseases affect serum urea concentration which provides a sensitive indicator of such disease. The blood urea nitrogen (BUN) test, a routine but critical clinical laboratory assay used to evaluate renal function, quantifies serum urea that is produced in the liver as an endpoint of protein degradation. Studies are proposed that will lead to the development of a fluorescence-based biosensor capable of quantifying urea in a sample in real time. The sensor will employ the UreR protein encoded by the urease operon of the uropathogenic bacterial species Proteus mirabilis. UreR, to date, is the only documented urea-binding protein. When UreR binds urea, the protein undergoes a conformational change that is detectable using fluorescence technology. Three approaches to biosensor design will include fluorescent labeling of genetically modified UreR, fluorescence resonance energy transfer of UreR-Yellowfluorescent-protein fusions, and an anisotropy approach using the binding of its target DNA by UreR. The proposed UreR biosensor will directly measure urea in real time without the necessity of hydrolyzing urea with urease, which is required in current sensor technology. Primary applications may include routine blood urea nitrogen determination and monitoring of blood urea nitrogen directly in the blood of patients undergoing kidney dialysis. In addition, the biosensor will be useful in basic science investigations including urea transport in the liver and kidney, the role of urea hydrolysis in urolithiasis, and urea metabolism in the gastric mucosa infected by ureasepositive Helicobacter pylori. This biosensor also offers the prospect of imaging urea concentration and fluxes in tissue using fluorescence and confocal microscopy. Our experimental approaches are organized into three Specific Aims: 1) To define the urea binding domain of the UreR protein 2) to develop a urea sensor using UreR; and 3) to construct a prototype UreR-based urea sensor and validate it in specific applications.

Project Title: DFT INVESTIGATIONS OF MN(II/III) OXALATE OXIDASE MODELS Principal Investigator & Institution: Chang, Christopher H. Chemistry; University of Florida Gainesville, FL 32611 Timing: Fiscal Year 2002; Project Start 04-MAR-2002 Summary: (provided by applicant): Several chronic ailments stem from the body?s inability to catabolize or excrete excess oxalic acid, including kidney stones and potentially fatal primary hyperoxaluria. Future treatment methods could include the use of enzymes from other organisms to digest oxalate into molecules that are more easily metabolized and excreted. Two such enzymes are an oxalate decarboxylase that transmutes oxalate into formate and carbon dioxide, and oxalate oxidase that produces carbon dioxide and hydrogen peroxide from oxalate and oxygen. Both enzymes contain manganese, and the decarboxylases appear to be a genetic duplication of the oxidases. How duplication leads to a change in overall reaction is currently mysterious. This project seeks to establish procedures by which the catalytic and structural properties of
Studies 17
these oxalate-degrading enzymes may be calculated from first principles. Density functional, semi-empirical, and free energy perturbation-molecular dynamics methods will be used to calculate geometries, EPR hyperfine coupling parameters, ultravioletvisible spectra, and reduction potentials of a variety of Mn (II/III) complexes with oxygen and/or nitrogen ligation. The method will be tested on the active site of superoxide dismutase, an enzyme with extensive experimental data available and identical ligands to those of oxalate oxidase. Methods developed for the dismutase active site will be valuable once the decarboxylase structure becomes known. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen ·
Project Title: DIET SALT, CALCIUM KIDNEY STONES, BONE IN STONE FORMERS Principal Investigator & Institution: Massey, Linda K. Professor; Food Science & Human Nutrition; Washington State University 423 Neill Hall Pullman, WA 99164 Timing: Fiscal Year 2001; Project Start 15-SEP-2001; Project End 31-DEC-2003 Summary: (Scanned from the applicant's description): Increases in dietary salt, i.e. sodium chloride (NaCI), increase urinary calcium over the range of intakes commonly consumed. Both salt loading studies and reports of within-population correlations find that increased urinary calcium losses are approximately 1 mmol (40 mg) for each 100 mmol (2300 mg) increase in dietary NaC1. Individuals with hypercalciuria and/or a history of calcium kidney stones appear to have 2 times greater proportional increases in urinary calcium per 100 mmol increase in salt intake. Thirty-two subjects with a history of at least one calcium oxalate kidney stone will be recruited; 16 with hypercalciuria, 16 normocalciuria. This study consists of two, seven-day periods. For all seven days of both dietary treatments, each participant will eat only the foods provided by the investigators, a nutritionally adequate diet prepared from common foods containing 50 mmol/d salt. The first five days of each treatment (adaptation), the participant will be free-living, the sixth and seventh in the WSU metabolic unit. One of the two weeks, 150 mmol supplemental salt will be added as tablets taken with each meal; the total of 200 mmol is the average consumption measured in previous studies of stone formers. The major outcome measures are urinary oxalate, calcium, magnesium, phosphate and citrate, and two measures of calcium salt saturation as indicators of risk of calcium salt precipitation. The two measures of calcium salt precipitability will be the Tiselius risk index, a measure of calcium oxalate precipitability from solution which includes the effects of volume, magnesium and citrate concentrations as well as calcium and oxalate, and Ap (CaP), a measure of calcium phosphate precipitability from solution, which includes the effects of volume, citrate and pH as well as calcium and phosphate. Because increased urinary calcium loss from adding salt occurs, bone breakdown may be increased in compensation, so 4 markers of bone turnover will be measured, bone alkaline phosphatase, osteocalcin, deoxypyridinoline, and Ntelopeptide. We will also compare the responsiveness of hypercalciuric vs normocalciuric participants for all the outcome variables, because the literature suggests that hypercalciuric stoneformers may be more sensitive to dietary salt effects on urinary calcium. Reduction of dietary NaC1 from typical intakes of 200 mmol/day to an intake of 50 mmol/day may decrease the risk of recurrence of calcium-containing kidney stones and slow rates of bone loss, thus reducing risk of osteoporosis as well.

Project Title: DIETARY OXALATE AND KIDNEY STONE FORMATION Principal Investigator & Institution: Assimos, Dean G. Professor; Neurology; Wake Forest University Health Sciences Winston-Salem, NC 27157 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2006 Summary: (provided by applicant): Calcium oxalate kidney stone formation affects a significant number of individuals in the United States and contributes billions of dollars to health care costs. Urinary oxalate excretion plays a major role in the formation of these calculi as it influences the supersaturation of urine with calcium oxalate, a prerequisite for calcium oxalate stone formation. Recent investigations have shown that a significant amount of urinary oxalate is derived from dietary sources. Therefore, reducing oxalate consumption or its absorption from the intestinal tract may prove to be useful methods for limiting an individual's risk of forming stones. Experiments with cultured cells and animal models have demonstrated that oxalate has the potential to damage renal tissue through the generation of chemicals called oxygenated free radicals. This process may play a causative role in calcium oxalate stone formation. Therefore, attenuating this response may also limit stone generation.There are three specific aims in this research proposal. The first is to compare the response of stone forming and nonstone forming adults to dietary oxalate. The second aim is to compare renal oxalate clearance in both of the aforementioned groups. These studies will determine whether there are any differences in the renal handling of oxalate between these two groups. The third aim is to determine whether urinary oxalate excretion and renal proximal tubular cell injury can be reduced with calcium supplements, vitamin E supplements, administration of oxalate degrading bacteria, or a combination of all three of these regimens. All of these studies will be conducted in our General Clinical Research Center where carefully controlled diets can be administered. Various responses will be assessed including gastrointestinal oxalate absorption, urinary supersaturation, oxalate excretion, oxidative stress and markers of renal proximal tubular cell injury. These studies will aid in the development of strategies to prevent kidney stone formation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: DIGESTION OF FOOD OXALATE Principal Investigator & Institution: Sidhu, Harmeet;; Ixion Biotechnology, Inc. Box 13, 13709 Progress Blvd Alachua, FL 32615 Timing: Fiscal Year 2001; Project Start 15-FEB-2000; Project End 31-AUG-2003 Summary: provided by applicant): Calcium oxalate stone disease is a prevalent disease with limited preventative treatment options. Dietary oxalate makes an important contribution to urinary oxalate excretion and a strong body of evidence suggests it plays an important role in calcium oxalate stone formation. The long-term objective of this project is to develop a commercial product based on the oxalate-degrading bacterium, Oxalobacter formigenes, which can reduce the absorption of dietary oxalate when taken with meals. The first two specific aims are designed to test the safety and efficacy of this approach. In these studies normal, healthy volunteers will consume diets with controlled contents of oxalate and other key nutrients. In the first specific aim in an oxalate load study, which simulates a single meal, the optimal dose of bacteria required to reduce oxalate absorption from the load will be determined. In the second specific aim this dose will be used to determine the effects of bacteria taken with each meal for 4 days. The urinary excretion relative to that of creatinine will be used as an index of oxalate absorption in each study. The third specific aim will optimize fermentation and freeze drying conditions to produce a product with satisfactory cost, efficacy, safety and

shelf life. Due to the wide spread occurrence of stone disease this product has the potential to be a viable treatment to prevent the formation of kidney stones.. PROPOSED COMMERCIAL APPLICATION: Urolithiasis is a common disease with few therapies that are effective in eliminating recurrences in susceptible individuals. Thus there is a large market for a product that can reduce urinary oxalate excretion that could benefit all calcium oxalate stone formers. The proposed therapy is to degrade dietary oxalate in the GI tract before it could gen absorbed. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen ·
Project Title: EFFECT OF ENALAPRIL ON URINARY CITRATE EXCRETION Principal Investigator & Institution: Sakhaee, Khashayar;; University of Texas Sw Med Ctr/Dallas Dallas, TX 753909105 Timing: Fiscal Year 2001 Summary: This study will determine if angiotensin converting enzyme inhibitors in humans exert a significant effect on urinary citrate excretion. Because these drugs are commonly used to treat many renal and cardiovascular diseases, knowledge of their effect on urinary citrate excretion would be important before prescribing them to persons at risk for developing kidney stones..

Project Title: GENETIC MAPPING IN THE HYPERCALCIURIC STONE-FORMING RAT Principal Investigator & Institution: Scheinman, Steven J. Professor; Medicine; Upstate Medical University Research Administration Syracuse, NY 13210 Timing: Fiscal Year 2001; Project Start 01-JUN-2000; Project End 30-APR-2004 Summary: Idiopathic hypercalciuria (IH) is the most common metabolic abnormality associated with kidney stones in humans, and as many as 45 percent of patients with IH have a family history of nephrolithiasis. Defined subsets of patients with hypercalciuric nephrolithiasis include those with autosomal or X linked inheritance, but overall the phenotype of human IH is that of a complex, polygenic disease. A full-scale investigation of the genetics of human hypercalciuria would be made difficult by the large number of families required, dietary variables, and number of metabolic subsets described in patients with IH. However, an animal model exists in the genetic hypercalciuric stone-forming (GHS) rat, which is now in its 51st generation of inbreeding. The physiology of hypercalciuria in this model has been extensively characterized and resembles human IH in many important respects. The GHS rat colony was established by Dr. David Bushinsky by selectively breeding the most hypercalciuric littermates of each generation, and is likely to be enriched in alleles for genes that contribute to hypercalciuria. A robust armamentarium of tools for genetic and physical mapping in rats is now available, and expanding rapidly. The goal of this project is to map genes determining hypercalciuria in the GHS rat. The first aim of this project is to identify quantitative trait loci (QTL) linked to hypercalciuria through QTL mapping. This analysis will make use of selective genotyping of an F2 intercross between GHS and normocalciuric Wistar-Kyoto (WKY) rats, using simple sequence-length polymorphisms (SSLPs). The second aim is to refine the QTL localization further by constructing and analyzing congenic strains of rats. We have made substantial progress towards a whole-genome scan in an initial F2 of 156 rats, and have identified one QTL on chromosome 1 that meets conservative criteria for significance (LOD 4.5) and two loci that meet criteria "suggestive" of linkage. More precise localization should eventually

make possible physical mapping and positional cloning of genes contributing strongly to hypercalciuria, which will allow for future work in which homologues of these genes can be studied to determine their role in human idiopathic hypercalciuria.

Project Title: HYPEROXALURIA AND TUBULE INJURY AND KIDNEY STONE DISEASE Principal Investigator & Institution: Mandel, Neil S. Professor; Medicine; Medical College of Wisconsin Po Box26509 Milwaukee, WI 532264801 Timing: Fiscal Year 2003; Project Start 01-MAR-2003; Project End 28-FEB-2005 Summary: (provided by applicant): Kidney stone disease is a substantial health problem associated with significant pain, suffering, and economic costs. 5% to 15% of the population will have a symptomatic episode of a stone by the age of 70 and at least 50% of these individuals will have recurrent disease. To date, urolithiasis researchers have been limited to cell culure studies or a rat model where hyperoxaluria is induced by either ethylene glycol oral administration that is toxic to multiple organs or by high dose intraperitoneal sodium oxalate injection. The levels of induced urinary oxalate excretion in the rat needed to produce oxalate crystalluria and tisssue or cell response are criticized as being supraphysiologic compared to man. We propose that the pig is ideal for the development of an animal model of calcium oxalate crystalluria and calcium oxalate stone disease. The anatomy and physiology of the pig kidney is very similar to man. The anerobic bacteria Oxalobacter formigenes degrades oxalate to formate in the pig gut and normally stops the pig from becoming hyperoxaluric. We have successfully obtained Oxalobacter formigenes free pigs and report here for the first time that these pigs demonstrated a significant increase in urinary oxalate excretion as the result of an oral oxalate load similar to that experienced by man ingesting an oxalate rich diet. We propose to induce hyperoxaluria in the pig by feeding them an oxalate rich diet. We propose to study the effect of hyperoxaluria on pig kidney physiology and its impact on calcium oxalate crystal attachment and stone maturation. We hypothesize that pigs fed oxalate will form calcium oxalate crystalluria and calcium oxalate stones in their urinary tract in a manner very similar to man. We also hypothesize that these hyperoxaluric pigs are ideally suited for the extension of studies on the effect of hyperoxaluria on renal epithelial cell physiology, crystal attachment and stone maturation. This grant proposal contains three Specific Aims that test our hypotheses:Specific Aim I: To develop a new hyperoxaluric pig animal model.Specific Aim II: To initiate calcium oxalate crystalluria in the pig and to identify the site of crystal attachment along the nephron.Specific Aim III: To induce calcium oxalate stone disease in the pig and to characterize the process of stone maturation. These Specific Aims and their associated questions will allow us to fully describe the development of hyperoxaluria in the pig and the development of calcium oxalate crystalluria and calcium oxalate stones. The hyperoxaluric pig will have great potential in the advancement of many areas of urolithiasis research and in the design of new therapeutic modalities for the treatment of stone disease.

Project Title: MECHANICAL ORGINS OF SHOCK INDUCED BIOEFFECTS IN SHOCK WAVE LITHOTRIPSY Principal Investigator & Institution: Sturtevant, Bradford;; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, IN 462025167 Timing: Fiscal Year 2001
Studies 21
Summary: This grant is the continuation of a collaborative multi-disciplinary study of the mechanical initiation of injury to soft tissue in the kidney and of damage to tissue analogs by ESWL shock waves. Experiments are carried out in a laboratory lithotripter of our own design that mimics the Dornier HM3 electrohydraulic lithotripter. Finitedifference numerical solutions of the Euler equations are obtained for focusing shock waves interacting with tissue and kidney stones.. Cooperative research is carried out with the other Projects of this Program Project Grant to advance the objectives of the Grant. The aims of this Project are: I. Extend the dose criterion developed in our previous work on the cavitation-free failure of planar membranes to more complex weak mechanical structures and, in collaboration with Project 2, to in vitro cell cultures. Included in this aim is the development of a tissue phantom which reliably mimics the shock-wave scattering properties of soft tissue, development PVDF transducer arrays, investigation of membrane material/cavitation-free host fluid combinations and thinmembrane cylindrical structures for damage studies, and collaborations with Projects 1 and 2 to develop a physically-based quantitative definition of ESWL dose. II. Initiate a new effort in Project 4 to demonstrate the mechanisms of kidney stone comminution by ESWL. Included in this aim is utilization of the Hopkinson bar technique to characterize the failure dynamics of real and phantom calculi, and development of a stone phantom which faithfully mimics the failure models of kidney stones.. III. Develop numerical methods for solving the exact Euler equations of motion. Included in this aim is adaptation of the Amrita problem-solving environment to shock wave focusing problems, calculation of shock wave focusing by an ellipse in uniform and non-uniform media, and calculation of wave shapes and compressive stresses induced by impingement of a shock wave on a theoretical calculus. The hypothesis that the above aims are designed to test include: 1. A quantitative definition of ESWL dose, based on the physical properties of waves and tissue, can be developed to quantify the mechanical input of ESWL to tissue. 2. Comminution of kidney stones in ESWL occurs under shock compression by dynamic fatigue. 3. Accurate numerical calculations of shock pressure and wave geometry during shock wave focusing can be used with experimental data to elucidate mechanisms of stone comminution and tissue injury.

Project Title: MOLECULAR MECHANISM OF RENAL NA+ DEPENDENT COTRANSPORT Principal Investigator & Institution: Pajor, Ana M. Professor; Physiology and Biophysics; University of Texas Medical Br Galveston 301 University Blvd Galveston, TX 77555 Timing: Fiscal Year 2001; Project Start 01-APR-1993; Project End 31-DEC-2001 Summary: (Adapted from the Applicant's Abstract): The long-term objective of this project is to determine how the structures of sodium-dependent cotransport proteins determine their functional properties. The focus of the current proposal is to characterize at the molecular level the Na+/dicarboxylate cotransporters of the renal proximal tubule. These transporters are important to the function of the kidney in their reabsorption of Krebs cycle intermediates, and play a role in acid-base balance and organic anion excretion. The brush border Na+/dicarboxylate cotransporter has been implicated in the development of kidney stones by its regulation of urinary citrate concentrations. The principal investigator has recently cloned and sequenced a rabbit renal Na+/dicarboxylate cotransporter, NaDC-1 and the human homolog, hNaDC-1. NaDC-1 appears to correspond to the low affinity Na+/dicarboxylate cotransporter of the brush border membrane. The first Specific Aim of this study is to determine the role that histidine-106 plays in the transport of succinate by NaDC-1 and hNaDC-1. The
22 Kidney Stones
second Specific Aim is to identify domains or residues involved in substrate selectivity and binding, by preparing chimeras between related transporters. The third Specific Aim is to clone the renal high affinity Na+/dicarboxylate cotransporter. This transporter will be used to identify residues important for high affinity substrate binding. These studies should provide fundamental information on the functional properties of this family of sodium-dependent transporters, and on the physiological role of these transporters in the kidney.

Project Title: MOUSE EXTRACELLULAR CALCIUM SENSING RECEPTOR Principal Investigator & Institution: Pollak, Martin R. Assistant Professor of Medicine; Brigham and Women's Hospital 75 Francis Street Boston, MA 02115 Timing: Fiscal Year 2001; Project Start 26-SEP-1997; Project End 31-AUG-2004 Summary: Extracellular calcium homeostasis is precisely regulated by the interaction of several hormones with multiple target organs. In addition, calcium itself acts upon a Gprotein-coupled "calcium- sensing" receptor (CaSR) on the he surface of parathyroid cells to regulate the secretion of parathyroid hormone (PTH). This receptor is also expressed in other tissues, where its precise function is less well-defined. Humans with two copies of an inactivating mutation in the caSR gene are severely hypercalcemic, presumably because the normal inhibition of PTH secretion by calcium is no longer present. CaSR is expressed by diverse cell types of the kidney, where extracellular calcium has multiple effects. The purpose of this proposal is to clarify the role of CaSR in mediating specific effects of calcium on the kidney and to better define the role of renal CaSR in regulating whole animal calcium homeostasis. The aims of this proposal focus on the development of genetically altered mice which will serve as models in understanding the function of renal Car. Transgenic mice overexpressing CaSR in the thick ascending limb of the kidney will be generated. This mouse model should help clarify the contribution of CaSR activation to the regulation of calcium, sodium, and water homeostasis. It will also aid in defining which actions of calcium on the kidney are mediated by CaSR. In addition, the renal function of mice with a null mutation in CaSR will be investigated by a combination of genetic and physiologic methods. Normally these ~knockout~ mice do not live past the neonatal period. Crossing CaSR deficient mice with other mutant mice unable to mount a hypercalcemic response to PTH should generate viable CaSR-deficient mice which will aid in the investigation of CaSR function in the kidney and other tissues. Multiple hypotheses regarding the role of CaSR in renal calcium excretion and as well as its role in mediating renal responses to calcium will be investigated. Clarifying the functions of CaSR, a newly identified component of the calcium homeostatic system, will likely have implications for understanding and treatment of diseases of abnormal calcium regulation, including osteoporosis, hyperparathyroidism, kidney stones, and hypertension.

industry. We found that crosslinked enzyme crystals (CLECs) show stability under low pH, on storage and against proteolysis. These properties make them ideal for gut lumenal therapy. The patient would swallow a tablet or liquid suspension of CLEC particles composed of a needed metabolic enzyme or protein. The CLEC agent would survive the harsh acidic pH and proteolytic environment of the stomach, and pass into the proximal small intestine. The CLEC particle would then carry out its therapeutic biochemistry within the gut lumen while remaining resistant to degradation by endogenous proteases. In this Phase I study, we propose to develop two types of CLECs: Oxalyl-CoA decarboxylase for oral lumenal therapy and Oxalate oxidase to be used in the extracorporeal device/dialysis equipment. The Oxalyl-CoA decarboxylaseCLEC will perform its action in the duodenum while remaining as crystalline material or by release of activity by dissolution of the CLEC particle. This target was chosen to address the problems of current therapies of hyperoxaluna caused by excessive absorption of oxalate due to the absence of Oxalobacter formigenes bacterium in the intestine or due to inflammatory bowel disease. In addition, Oxalate oxidase-CLEC may be used in dialysis equipment or extracorprealdevices to reduce the oxalate content of blood in patients with Primary Hyperoxaluria. If successful, these approaches will lead to the introduction of novel, efficient enzyme therapy for the prevention of Oxalate Kidney Stones..

Project Title: NOVEL INHIBITOR OF CRYSTAL ADHESION TO RENAL CELLS Principal Investigator & Institution: Lieske, John C. Associate Professor; Mayo Clinic Rochester 200 1St St Sw Rochester, MN 55905 Timing: Fiscal Year 2001; Project Start 01-MAY-1999; Project End 30-APR-2004 Summary: Nephrolithiasis, the formation of kidney stones, is a common condition seen in up to 12 percent of adults during their lifetime. As the mechanisms by which stones form are poorly understood, new knowledge is required to identify susceptible patients for early treatment and to formulate new therapeutic strategies to prevent the appearance of single and/or recurrent stones. How nascent crystals that nucleate in tubular fluid are retained in the nephron and form calculi is not known. My studies during the past 8 years demonstrate that calcium oxalate monohydrate (COM) crystals bind within seconds to anionic, sialic acid- containing glycoproteins on the apical surface of cultured monkey kidney epithelial cells (BSC-1), employed to model the tubule, suggesting one mechanism whereby crystals could be retained in the kidney in vivo. Preliminary studies have identified constitutive release of a protein by BSC-1 cells that blocks adhesion of COM crystals to the apical cell surface; it has been named the Crystal Adhesion Inhibitor, or CAI. A novel method employing COM crystal affinity chromatography was used to purify CAI. Evidence provided in this revised application demonstrates that CAI is a constituent of normal human urine. Biochemical characterization identifies it as a sialic acid-containing glycoprotein. Microsequencing of the amino terminus and 9 fragments generated by lys-C and asp-N protease cleavage reveal that CAI is novel. Two monospecific antibodies against synthetic peptides prepared using amino acid sequence information each recognize the factor on Western blots of partially- purified normal human urine, renal cell conditioned medium, and total kidney cell protein. The goal of this revised research plan is to define the potential role of CAI in human nephrolithiasis. New Specific Aims are to: 1) Utilize 2 monospecific antibodies prepared against CAI to characterize and quantitate it in the urine of normal and stone- forming individuals; 2) Study inhibition of COM, hydroxyapatite, and uric acid crystal adhesion to renal cells by CAI isolated from
24 Kidney Stones
conditioned medium and the urine of normal and stone-forming subjects; 3) Study inhibition of COM crystal growth by CAI isolated from conditioned medium and the urine of normal and stone-forming subjects, 4) Study inhibition of COM crystal aggregation by CAI isolated from conditioned medium and the urine of normal and stone-forming individuals, 5) Utilize the monospecific antibodies prepared against CAI to isolate affinity-purified protein and study its physical-chemical properties; 6) Study the cell biology of CAI. Achieving these specific aims will provide new knowledge about mechanisms that mediate stone formation, and provide a rational basis for design of novel strategies to treat and/or prevent this disease.

Project Title: PREDICTING KIDNEY STONES IN RELATIVES OF STONE FORMERS Principal Investigator & Institution: Coe, Brian J.; Litholink Corporation 2250 W Campbell Park Dr Chicago, IL 60612 Timing: Fiscal Year 2001; Project Start 01-AUG-1999; Project End 31-JAN-2003 Summary: The overall aim of Phase I and Phase II is to determine, if any, of the established urinary chemical abnormalities central to the pathogenesis of nephrolithiasis can be used prospectively to predict new onset of kidney stone disease in non-stone forming family members of calcium stone formers. This study proposes to measure potential urinary risk factors in all first degree relatives of the stone former (proband) upon entrance into the study and then follow subject for an average of 5 years in order to record stone formation and related morbidity. We will use a multivariate discriminate analysis to determine the independent predictors of new onset stone formation in family members. Family members at high risk might benefit from subsequent changes in lifestyle, diet, fluid intake or, possibly, pharmaceutical intervention that could stave off stone disease. To date no clinical trials have examined whether metabolic (laboratory) evaluation of health family members can predict stone formation. In addition to the established urine chemistries, we will examine whether a crystal growth assay can be a useful tool in predicting new stone formation. PROPOSED COMMERCIAL APPLICATIONS: Because of the extreme pain and suffering faced by kidney stone formers, many family members of stone formers are concerned about the possibility of their developing the disease. If we are able to establish which urinary markers for stone formation are predictive of disease onset in family members of stone formers, we will have developed a new indication for the testing which we currently sell.

Principal Investigator & Institution: Stayton, Patrick S. Bioengineering; University of Washington Seattle, WA 98195
Studies 25
Timing: Fiscal Year 2001; Project Start 30-SEP-1997; Project End 31-JUL-2002 Summary: Acidic proteins found in mineralized tissue act as biology's crystal engineers. Their activities are responsible for the material properties of hard tissues, and their activities directly control the hierarchical architecture of these tissues. However, despite their importance in such fundamental physiological processes as bone and tooth formation, there is remarkably little known of the protein structure-function relationships which govern crystal recognition. The primary goal of this program is to obtain a molecular description of the structure-function relationships used by small acidic proteins in the crystal engineering of hydroxyapatite and calcium oxalate (the principle mineral phases of bone/teeth and kidney stones, respectively). Preliminary genetic engineering results with a small model protein, consisting structurally of a long alpha-helix and two antiparallel beta-sheets, have demonstrated that the protein surface electrostatic charge distribution can directly dictate whether secondary nucleation and crystal growth is promoted or inhibited. The molecular recognition mechanisms underlying this observation will be studied with a combination of kinetic and thermodynamic techniques, along with direct solid-state NMR determination of the protein-crystal interfacial structure. Further studies will characterize how secondary structure scaffolds are used to present carboxylate side-chains with stereospecificities that direct interactions with hydroxyapatite and calcium oxalate. Genetic engineering techniques will be used to systematically place carboxylate side-chains on the alphahelix and anti- parallel beta-sheets, and the subsequent molecular interactions with the crystals will again be studied with solid-state NMR techniques. In addition, the functional properties of these proteins will be assessed using a variety of techniques including constant composition kinetics, direct binding adsorption analysis, particle size determination, electron microscopy, and zeta-potential measurements. The disruption of normal biomineralization processes can lead to pathological mineralization or demineralization, such as in atherosclerotic plaque formation, artificial heart valve calcification, kidney stone build-up, dental calculus formation, or bone and tooth demineralization. A better understanding of the biomolecular mechanisms used to promote or retard crystal growth could provide important design principles for the development of calcification inhibitors and promoters in orthopaedics, cardiology and dentistry.

Project Title: REGULATION OF ENTERIC HYPEROXALURI BY OXALOBACTER Principal Investigator & Institution: Peck, Ammon B. Professor; Pathology, Immunol & Lab Med; University of Florida Gainesville, FL 32611 Timing: Fiscal Year 2001; Project Start 27-MAR-1998; Project End 28-FEB-2003 Summary: Oxalobacter formigenes, a recently identified bacterium that colonizes the gastrointestinal (GI) tracts of all vertebrates, has gained considerable attention due to its important symbiotic relationship with its hosts in regulating oxalic acid absorption in the intestines as well as oxalic acid levels in plasma two factors associated with the risk to develop calcium-oxalate kidney stones.. Oxalic acid is a by-product of metabolism and a common constituent of most diets; however, if permitted to accumulate, it can cause numerous pathological conditions, including hyperoxaluria, cardiac conductance disorders, calcium oxalate stones, renal failure, death and possibly inflammatory bowel disease and vulvovestibulitis. Despite the potential significance of O. formigenes in controlling enteric hyperoxaluria, and thus oxalate-related disorders, research has been limited due to inherent difficulties in culturing and identifying this bacterium. Nevertheless, preliminary studies already suggest a correlation between the number of
26 Kidney Stones
colony forming units of Oxalobacter sp. per gram feces and the frequency of recurrent urolithiasis, inflammatory bowel disease and hyperoxaluria/nephrocalcinosis in cystic fibrosis. With the development of a rapid and sensitive DNA-based detection system highly specific for O. formigenes, we are now able to investigate the correlation between an increased risk for urolithiasis and the absence of O. formigenes from the GI tract. Using the laboratory rat as a model, we propose to: 1) study the colonization of noncolonized rats with various sub-strains of O. formigenes to determine if variations exist in the efficacy of different strains of O. formigenes to colonize and if primary colonization precludes secondary colonizations, 2) determine whether O. formigenes can prevent hyperoxaluria and subsequent formation of calcium-oxalate crystals in rats colonized with various sub-strains of the bacterium and challenged with high oxalatecontaining diets, and 3) examine the relationship between diet and/or antibiotic treatment with subsequent decolonization of the GI tract by O. formigenes known to occur in human populations and whether decolonization of the GI tract is irreversible. Results from these studies should provide insight into the role O. formigenes plays in regulating oxalate homeostasis in vertebrates, including humans, and should offer new modalities in prevention therapy for oxalate-associated disorders, such as recurrent kidney stone formation.

Project Title: RENAL BASIS OF HYPOCITRATURIA Principal Investigator & Institution: Alpern, Robert J. Dean; University of Texas Sw Med Ctr/Dallas Dallas, TX 753909105 Timing: Fiscal Year 2001 Summary: (Taken directly from the application) Hypocitraturia is an important cause of kidney stones.. Citrate is freely filtered in the glomerulus, and urinary citrate excretion is regulated principally by the rate of citrate reabsorption and metabolism in the proximal tubule. Reabsorption is mediated by an apical membrane 3Na+/citrate cotransporter encoded by the NaDC-1 gene, and metabolism is mediate by one of two pathways: a mitochondrial pathway that mediates citrate metabolism in the tricarboxylic acid cycle; and a cytoplasmic pathway in which ATP citrate lyase metabolizes citrate to acetyl CoA and oxaloacetate. The proposed studies will examine the molecular mechanisms responsible for regulation of citrate reabsorption and metabolism, focusing on NaDC-1. Studies in Aim 1 will address the molecular mechanisms of NaDC-1 regulation in rats with chronic metabolic acidosis, K+ deficiency, alkali feeding, and starvation. Studies in Aim 2 will further address the molecular mechanisms of NaDC-1 regulation in cultured proximal tubule cells exposed to acidic extracellular fluid. These studies will utilize cells expressing native NaDC-1, as well as cells expressing stably transfected tagged NaDC-1, and transiently transfected reporter constructs. Aim 1 and 2 together will address the regulation of NaDC-1. Studies in Aim 3 will address the role of signaling pathways known to be activated by acidosis in the regulation of NaDC-1. These pathways include: 1) tyrosine kinase and MAP kinase pathways; 2) glucocorticoids; and 3) endothelin. Studies in Aim 4 will quantitate citrate metabolism in mitochondrial and cytoplasmic pathways of the renal proximal tubule using 13C NMR spectroscopy. Lastly, studies in Aim 5 will address whether hyperkalemia causes hypercitraturia and thus is responsible for the lack of predisposition to nephrolithiasis in hyperkalemic renal distal tubular acidosis. These studies will allow us to continue to pursue an understanding of the mechanisms of regulation of renal citrate handling in the proximal tubule.

Project Title: RENAL CRYSTAL GROWTH INHIBITOR PROTEINS Principal Investigator & Institution: Kleinman, Jack G. Professor; Medicine; Medical College of Wisconsin Po Box26509 Milwaukee, WI 532264801 Timing: Fiscal Year 2001; Project Start 01-JUL-1995; Project End 31-MAR-2003 Summary: Kidney stones are a common clinical problem responsible for significant morbidity and economic costs in excess of 2 billion dollars/year. Despite progress in treatment, the recurrence rate of stones remains high. Interrupting early steps in the formation of kidney stones have the greatest likelihood of successfully preventing recurrence. These early steps include nucleation of stone crystals in tubular fluid and their growth and aggregation within the nephron to a size that can interact with some intrarenal structure. It is the hypothesis of this grant that these processes are primarily determined by specific interactions between stone constituent crystals and macromolecules present in tubular fluid and urine. The overall goal of this project is to advance our understanding of the role of one of these interactions by studying those of the principal urinary inhibitory macromolecule osteopontin/uropontin (OPN) and other macromolecular inhibitors of crystal formation in general in the development of kidney stones.. The specific aims are: (1) Determining structural motifs of OPN responsible for effects on nucleation, growth, aggregation of calcium oxalate and hydroxyapatite (crystal formation), specifically, (a) the contributions of the N-terminal and C-terminal halves of the molecule, (b) the roles of putative Ca-binding sites, and (c) the effects of post-translational modifications; (2) Characterizing OPN from normals and Ca stoneformers with respect to its effects on crystal formation, including, (a) isolation and biochemical characterization of OPN from urine of normals and stone-formers, and (b) determining whether OPN from Ca-stone formers inhibits stone crystal formation to the same degree as OPN from normal individuals; (3) Investigating the physical chemistry of the interaction of OPN and other macromolecules and stone crystals, by determining (a) the quantitative relationship between macromolecules and growing crystal nuclei, (b) the relationship between their structure and crystal formation, and (c) the effects of the reactions conditions on the interaction between them and growing crystal nuclei, and by examining (d) the interactions between immobilized macromolecules and crystal formation; (4) Examining the effects of regulating OPN production on an experimental model of CaOx stone disease. Specifically, (a) determining whether pharmacolgic upregulation of OPN production ameliorates crystal deposition in animals given Na oxalate either acutely or chronically, (b) developing an in vivo system for transient renal expression of OPN, and (c) determining whether upregulation of OPN expression protects and down-regulation aggrevates crystal deposition in animals given Na oxalate either acutely or chronically.

Project Title: RISK FACTORS FOR RECURRENT NEPHROLITHIASIS Principal Investigator & Institution: Curhan, Gary C. Associate Professor of Medicine; Brigham and Women's Hospital 75 Francis Street Boston, MA 02115 Timing: Fiscal Year 2002; Project Start 15-MAR-2002; Project End 31-DEC-2006 Summary: (provided by applicant): We propose to build upon our initial findings of factors that influence risk of nephrolithiasis, which occurs in 12 percent of the US population and causes tremendous pain and suffering. Using a prospective study design, the primary objective is to identify and evaluate dietary and urinary risk factors for recurrent nephrolithiasis in female and male participants of three large prospective cohort studies: the Nurses' Health Study I (121,700 women), the Nurses' Health Study II
28 Kidney Stones
(116,671 women), and the Health Professionals Follow-up Study (51,529 men). Detailed dietary data are collected and updated in all three cohorts, and 24-hour urine samples were previously collected from a subset of subjects with incident kidney stones from all three cohorts. During the proposed 5-year study period, we will identify and confirm incident and recurrent kidney stones by medical record review. Further, we will collect two 24-hour urine samples from newly confirmed incident cases and randomly selected controls to measure 24-hour urine excretion of calcium, oxalate and other relevant factors. We will test the hypotheses that dietary and urinary factors proposed to be associated with incident stone formation are associated with recurrent stone formation. We also will explore interactions between dietary and urinary factors, especially calcium intake and urinary calcium excretion and risk of stone recurrence. Furthermore, we will examine if recurrence rates differ by gender and, if so, whether these differences can be explained by differences in dietary or urinary factors. Basing these analyses in these three existing cohorts has several major strengths. A substantial number of incident cases (n = 4953) and recurrent cases (n = 1114) have already been identified. The completeness of follow-up and the vast amount of information already collected make this a rich resource, particularly to study interactions between diet and urinary factors. Several important and intriguing results regarding kidney stone formation have already emerged from the cohorts. The study design and use of existing data provide an efficient means to increase the scientific value of these cohorts and to test several hypotheses of public health importance.

Project Title: ROLE OF BIOPOLYMERS AND LIPIDS IN KIDNEY STONE FORMATION Principal Investigator & Institution: Gower, Laurie A. Assistant Professor; Materials Science and Engr; University of Florida Gainesville, FL 32611 Timing: Fiscal Year 2001; Project Start 15-JUL-2001; Project End 30-JUN-2005 Summary: The objective of the proposed bioengineering research partnership (BRP), located at the University of Florida, is to examine two key issues relevant to urolithiasis; 1) the effects of acidic biopolymers and lipid membranes on nucleation, growth and aggregation of calcium oxalate (CaOx) crystals in an artificial urinary environment; and 2) the injurious effects of a liquid-phase mineral precursor on tubular epithelial cells grown in culture. With regard to 1), many investigators have examined the promotory and inhibitory effects of acidic glycoproteins on crystal growth and aggregation. Our work differs in that a primary focus will be to investigate the relevance of a recently discovered polymer-induced liquid-precursor (PILP) process to pathological biomineralization. The PILP process generates non- equilibrium crystal morphologies which exhibit features similar to crystals found in kidney stones, such as for example, stratified spherulites. Mineral films and coatings are also deposited by the process, and repetitive depositions might lead to concentrically laminated structures, such as those commonly observed in composite stones. In addition, the interfacial aspects of this liquid-liquid phase separation process lead to a pronounced aggregation tendency of crystals. Lastly, we hypothesize that the presence of this cementatious mineral precursor in the urinary tract could influence the attachment and retention of crystals to renal epithelial cells; or the highly ionic precursor phase could cause cell injury or death, leading to the release of modulatory factors or membrane fragments, which could promote heterogeneous nucleation and/or aggregation of crystals. The proposed work consists of ten Specific Aims which fall under four topical areas: crystal-macromolecule, crystal- crystal, crystal-lipid, and crystal-cell interactions. The bioengineering techniques
Studies 29
to be used include measurement of interparticle forces by Atomic Force Microscopy, measurement of long-range interactions between submicron CaOx particles and mimetic lipid membranes with an optical trap force transducer, and nucleation of crystals and PILP phase on mimetic lipid membranes using Langmuir monolayers. This 5-year project will enable us to assess the relevance of the PILP process to pathological calcification, as well as to perform a comparative analysis with the more traditional concepts pertaining to the role of lipids and acidic biopolymers in stone formation, and will contribute to the development of bioengineering techniques that are new to the field of stone research. The long-range clinical goal of this BRP is to provide a more effective means of diagnosis, treatment, and long-term prevention of renal calculi..

Project Title: SPS OF STRUCTURALLY DIVERSE AFGP ANALOGUES Principal Investigator & Institution: Ben, Robert N. Assistant Professor; Chemistry; State University New York Binghamton Vestal Pky E Binghamton, NY 13901 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 30-JUN-2006 Summary: (provided by applicant): The objective of this proposal is to facilitate a detailed understanding of how antifreeze glycoproteins (AFGPs) inhibit ice crystal growth. Towards this end, our laboratory has synthesized a series of first generation AFGP analogues and assessed their ability to inhibit ice crystal growth. Our approach centers on the preparation of glycosylated tripeptide building blocks that possess carbon-carbon linkages instead of carbon-oxygen linkages at the anomeric center. These building blocks (referred to as monomers) have been assembled into structural AFGP analogues using conventional solid phase synthesis (SPS). Preliminary data has shown that two of our C-linked AFGP analogues have antifreeze activity. This application describes studies designed to address what forces (hydrophilic or hydrophobic interactions etc.) are involved in AFGP function, and also, what structural features are necessary for antifreeze activity. The fact that the structures of these mimics are dramatically different than native AFGP suggests that the rational design of low molecular weight synthetic antifreezes is possible. Such compounds have tremendous potential as cryoprotective agents to protect cells from freeze-thaw damage and thus, have applications in cryomedicine where alternatives for the long-term storage of tissues and organs are urgently required. In addition, the concept of preventing or modifying ice crystal growth is a fundamental one that is closely related to biomineralization processes since; many biological molecules absorb onto crystalline surfaces and subsequently alter crystal growth. Examples of such processes include the deposition of cholesterol, the formation of gal bladder and kidney stones as well as consolidated biominerals such as bone and enamel. As a result, a detailed mechanistic understanding of how biological antifreezes function may have direct applications in many biomolecular processes of current medical interest.

Project Title: SWL AND RENAL INJURY AND STONE COMMINUTION Principal Investigator & Institution: Evan, Andrew P. Professor of Anatomy; Anatomy and Cell Biology; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, IN 462025167 Timing: Fiscal Year 2001; Project Start 10-MAY-1994; Project End 28-FEB-2003 Summary: Shock wave lithotripsy (SWL) is a very effective non-invasive treatment modality for the removal of upper urinary tract stones. However, SWL causes trauma to
30 Kidney Stones
the kidney that can lead to serious long-term complications in some individuals (e.g. new onset hypertension in the elderly; delayed kidney growth in the very young). While the efficacy of SWL is not in question, the severity of complications raises concern for the long-term safety of SWL. Little is known about the cellular level mechanisms involved in SWL injury and the tissue level changes that lead to chronic alterations in kidney structure and function. Likewise, it is not known how lithotripter shock waves (Sw's) break kidney stones.. Thus, the principal objectives of the proposed research are to determine: 1) the physical mechanisms of stone comminution and tissue damage in SWL; 2) the cellular mechanisms of SW- physical mechanisms of stone comminution and tissue damage in SWL; 2) the cellular mechanisms of SW-induced tissue injury; 3) the progression of tissue level changes initiated changes initiated by SW trauma that lead to scar formation; and 4) the factors (renal and extrarenal) that place patients at increased risk of injury. Our research effort in this Program Project Grant is organized around four Projects and two Cores. Project 1 (Indiana University & Methodist Hospital of Indiana) will use a whole animal model (pig) to determine how SW treatment causes renal hemorrhage and vasoconstriction, to define the tissue response that leads to scar formation and to assess for potential risk factors that may enhance SWL injury. Project 2 (Indians University) will use cultured cells and a variety of in vitro models that determine the cellular mechanisms involved in tissue damage and how acoustic cavitation and shear cause cell injury. Project 3 (University of Washington) will use sophisticated methods of cavitation to determine the role of cavitation in stone comminution and tissue injury. Project 4 (California Institute of Technology) will examine the role of shock waves shear as a fundamental mechanism that contributes to tissue failure and stone comminution. The overall goal of this research is to determine the physical mechanisms of stone comminution and the cause and consequences of SWinduced renal injury so that strategies can be devised to minimized or eliminate adverse effect while improving the efficacy of SWL.

Project Title: UROLITHIASIS AND PEROXIDATIVE INJURY Principal Investigator & Institution: Thamilselvan, Sivagnanam; Urology; Case Western Reserve Univ-Henry Ford Hsc Research Administraion Cfp-046 Detroit, MI 48202 Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-JUL-2004 Summary: Urolithiasis is a major health problem in the United States, and the incidence and frequency of stone formation appears to be increasing in this country. The current cost to the nation for treating kidney stones is approximaately 2.39 billion dollars/year. About two thirds of the stones contain calcium oxalate. Chances of recurrences within 10 years are nearly 60 percent. Treatment program includes medications, open surgery, percutaneous techniques and extra corporeal shock wave lithotripsy. Despite recent advances in treatment, stone recurrence can be reduced by only 50 percent. To reduce the likelihood of stone recurrence it is necessary to determine and understand the mechanisms involved in stone formation. Our working hypothesis is that cell injury is central to the process of urolithiasis and that prevention of cell injury will prevent calcium oxalate formation, retention and deposition. Hyperoxaluria and calcium oxalate crystalluria are often associated with increased excretion of tubular marker enzymes, a finding consistent with damage to renal tubular cells. Moreover, these changes are observed even in the absence of crystalluria, suggesting that oxalate induced membrane damage is not due solely to injury produced by calcium oxalate crystals. Our studies have suggested that oxalate induces peroxidative injury to the kidney tubules which can alter membrane permeability, and result in the deterioration of ability of the cells to
Studies 31
maintain normal ionic environment. The oxidant and antioxidant balance is therefore likely to be a critical determinant of cell sensitivity to free radical injury and a major impact on the magnitude of stone crystal nucleation on the injured renal tubular epithelium and the development of stone nidus. We propose to test this hypothesis in an animal model and renal epithelial cell culture (LLC-PK1 and MDCK). In an animal model hyperoxaluria is induced in male rats. In cell culture experiments, renal epithelial cells in culture are exposed to oxalate and calcium oxalate monohydrate crystals. The effect of antioxidants on these experimental models will be tested. These studies will provide valuable information on the importance of antioxidants in decreasing oxalate synthesis and deposition and, whether antioxidants offer promise as a therapeutic agent for recurrent stone formation.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print. 6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND KIDNEY STONES Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and kidney stones.
Finding Nutrition Studies on Kidney Stones The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “kidney stones” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 3. ALTERNATIVE MEDICINE AND KIDNEY STONES Overview In this chapter, we will begin by introducing you to official information sources on complementary and alternative medicine (CAM) relating to kidney stones. At the conclusion of this chapter, we will provide additional sources.
The Combined Health Information Database The Combined Health Information Database (CHID) is a bibliographic database produced by health-related agencies of the U.S. federal government (mostly from the National Institutes of Health) that can offer concise information for a targeted search. The CHID database is updated four times a year at the end of January, April, July, and October. Check the titles, summaries, and availability of CAM-related information by using the “Simple Search” option at the following Web site: http://chid.nih.gov/simple/simple.html. In the drop box at the top, select “Complementary and Alternative Medicine.” Then type “kidney stones” (or synonyms) in the second search box. We recommend that you select 100 “documents per page” and to check the “whole records” options. The following was extracted using this technique: ·
Foods that Fight Pain: Revolutionary New Strategies for Maximum Pain Relief Source: New York, NY: Harmony Books. 1999. 347 p. Contact: Available from Harmony Books. 231 Broad Street, Nevada City, CA 95959. (530) 265-9564. PRICE: $14.00. ISBN: 0609804367. Summary: This book is intended to help people fight pain by using common foods, traditional supplements, and herbs. It explains which foods contribute to pain and how to avoid them, which foods are pain-safe but high in nutrition, and which foods can actively soothe pain by improving blood circulation, relieving inflammation, and balancing hormones. An introduction describes how food can fight pain at any of the stages of the pain process: the initial injury, the inflammatory response, the pain message traveling through the nerves, and the brain's perception of pain. Part 1 discusses conditions related to poor circulation, such as backaches and chest pain. Part 2
70 Kidney Stones
addresses conditions caused by food sensitivities and inflammation, including migraines, other headaches, joint ailments, stomach aches and digestive problems, and fibromyalgia. Part 3 discusses hormone-related conditions such as menstrual pain, breast pain, and cancer pain. Part 4 discusses metabolic and immune problems, including carpal tunnel syndrome, diabetes, herpes and shingles, sickle cell anemia, kidney stones, and urinary infections. Part 5 discusses the roles of exercise, rest, and sleep in pain relief; describes several stress-reducing exercises; and explains why the body rebels against certain foods. The book includes menus and recipes, a glossary of ingredients, a list of resources, a list of suggested readings, and an index.
National Center for Complementary and Alternative Medicine The National Center for Complementary and Alternative Medicine (NCCAM) of the National Institutes of Health (http://nccam.nih.gov/) has created a link to the National Library of Medicine’s databases to facilitate research for articles that specifically relate to kidney stones and complementary medicine. To search the database, go to the following Web site: http://www.nlm.nih.gov/nccam/camonpubmed.html. Select “CAM on PubMed.” Enter “kidney stones” (or synonyms) into the search box. Click “Go.” The following references provide information on particular aspects of complementary and alternative medicine that are related to kidney stones: ·

CHAPTER 4. PATENTS ON KIDNEY STONES Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “kidney stones” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on kidney stones, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Kidney Stones By performing a patent search focusing on kidney stones, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. The following is an 8Adapted

Aiming system for kidney stone disintegrator Inventor(s): Dela-Cruz; Exequiel (Arlington Heights, IL), Burdick; Thomas H. (Deerfield, IL), Shene; William R. (Plattsburgh, NY), Nowacki; Christopher (Arlington Heights, IL), Brisson; Alfred G. (Kildeer, IL) Assignee(s): Northgate Research, Inc. (Arlington Heights, IL) Patent Number: 4,763,652 Date filed: April 16, 1986 Abstract: A kidney stone disintegrating system includes a computer-controlled aiming system. The disintegrating system includes a reflector containing water through which the reflector is coupled to a living body having a kidney stone. The reflector is a portion of an ellipsoid and a spark gap generator is located at one focus of the ellipsoid. An electrical energy source is connected to the spark gap generator for generating a spark which in turn generates a shock wave in the fluid. Three motors are connected to the reflector for moving it in respectively X-axis, Y-axis and Z-axis directions to locate the reflector so that the kidney stone lies at the second focus point thereof. A pair of ultrasound transducers are carried by an articulated support comprising a plurality of pivotally interconnected arms. Precision potentiometers are provided between the arms to indicate the relative positions thereof, and electrical potentials from the potentiometers are connected to a computer. The signals and the computer are connected to a monitor having a screen to display the kidney stone, and particularly the position thereof as determined by the two transducers. The computer is connected to the three motors to position the reflector in accordance with the positions of the transducers to locate the reflector with the second focus point coinciding with the kidney stone. Controls are provided for causing generation of a spark with the resulting shock wave focused on the kidney stone to destroy the kidney stone. Excerpt(s): Kidney stones, and also naturally-occurring stones in the bladder and the ureter can be exquisitely painful, and often require surgical relief. Excision or destruction of stones in the bladder and sometimes in the ureter can be relatively easily accomplished, but removal of stones from the kidney is a major procedure.... Removal of stones from the kidney is a very serious and traumatic procedure. A large incision is made in the body. The kidney is essentially removed from the body and cut open. The stone or stones are then removed, whereupon the kidney is sutured and returned to the body, with the body then being sutured. Typical recovery time is on the order of six months.... Chemotherapy is available as a non-invasive therapy for uric acid stones. In this therapy the urine is alkalized. The existing stone thus is dissolved over a substantial period of time, and in most cases the patient can be cured before his condition becomes acute. However, the patient's condition is often already acute when the stone is discovered, and immediate surgery is imperative. Attempts at chemical dissolution of other types of stones have not been successful. Web site: http://www.delphion.com/details?pn=US04763652__

Apparatus for contact-free disintegration of kidney stones or other calculi Inventor(s): Hausler; Eberhard (Saarbrucken, DE) Assignee(s): Richard Wolf GmbH (Knittlengen, DE) Patent Number: 4,311,147 Date filed: May 8, 1980 Abstract: This invention relates to apparatus for contact-free disintegration of kidney stones or other calculi of the kind in which electrical discharges are generated across an under water spark gap in the focus line of an elliptical reflector having annular or spiral surfaces. The calculus which is to be disintegrated is located into the focus of the reflector and in accordance with invention electrode elements are positioned at intervals in the focus line of this reflector on an insulating carrier. The latter is provided with high tension connectors at its ends and the electrode elements are arranged to form consecutive individual spark gaps.The gaps between the electrode elements may be of constant dimensions or may vary so as to produce variations in pressure distributed at a focus point if so desired. Excerpt(s): The present invention relates to a device for contact-free disintegration of kidney stones or other calculi, of the kind in which means are provided to generate discharges across an underwater spark gap in the focus line of an elliptical reflector having annular or spiral surfaces, into whose focus the calculus which is to be disintegrated is located. Hereinafter, such apparatus will be referred to as "of the kind described".... Apparatus for generating hydraulic shock waves is already known in which a copper wire is stretched over an insulating bracket in the focal point line of an elliptical annular surface reflector or torus reflector and this copper wire is vapourised throughout the length of the supporting bracket upon being connected to a source of high voltage and by virtue of the gas discharge formed generated the hydraulic shock wave, for the purpose of generating a shock wave under water. The wire must be pulled over the bracket again in each case to generate the following shock waves, and this requires considerable expenditure of time by the doctor. With this apparatus therefore, it is not possible, if at all, easily to generate shock waves following each other at short intervals.... It is an object of the invention to provide apparatus for generating a plurality or series of underwater discharges at the same time in the focal point line of the reflector, without special operations being needed for this purpose.

Assay for determining the propensity of a person to form kidney stones Inventor(s): Karasikov; Nir (3 Biram St., Haifa, IL), Sarig; Sara (19, Hamaapilim St., Jerusalem, IL) Assignee(s): none reported Patent Number: 5,064,765 Date filed: March 1, 1990 Abstract: There is provided an assay for determining the propensity of a person to develop a certain type of kidney stones which is based on the inter-action of the urine of such a person with aqueous solutions of compounds which interact to form such stones. The number and size distribution of resulting particles is determined and the results are evaluated. There is further provided a device for carrying out such an assay, comprising
84 Kidney Stones
means for interacting the urine of the patient with two solutions containing compounds which form kidney stones, means for breaking up crystal aggregates and means for passing a light beam through the sample positioned in a transparent container, and means for determining the number and size of the resulting particles. Excerpt(s): The invention relates to a novel method for determining the tendency of a person to develop kidney stones, and especially kidney stones of the oxalate type. The invention further relates to a device for carrying out such measurements and for their evaluation.... Other and further features of the invention will become apparent hereinafter.... The formation of stones in a kidney is a common pathological condition in humans. There exist a variety of kidney stones, according to their chemical composition, the most common consisting of calcium oxalate,.calcium phosphate and magnesium ammonium phosphate. It is important to find out whether a person has an inclination to form kidney stones, and of which type. This has been determined up to now mainly after surgery by analysis of the removed stones. In U.S. Pat. No. 4,399,003 there is described a method for diagnosing a patient's proneness to develop calcium oxalate kidney stones, which is based on an assay involving the urine of the patient and calcium and oxalate ions. The measurement is made by means of a calcium ion specific electrode. The present invention relates to an improvement of the said method. Web site: http://www.delphion.com/details?pn=US05064765__ ·
Device for disintegrating kidney stones by means of shock waves Inventor(s): Toftkjaer; Gert (Naerum, DK), Northeved; Allan (Farum, DK) Assignee(s): Non-Invasive Therapeutic Techniques A/S (Virum, DK) Patent Number: 4,844,081 Date filed: August 26, 1987 Abstract: A device for disintegrating kidney stones or gallstones by means of a focusing chamber being part of a rotation ellipsoid and comprising in one focal point a spark gap producing shock waves. Means fixing the device to the skin of the patient are provided in connection with the focusing chamber. A movable rubber sleeve or bellows may be provided in connection with the fixing means, said sleeve or bellows being glued onto the skin of the patient. As an alternative circumferential suction chambers may be provided along the rim of the sleeve, or the entire device may be shaped as a suction cup. An ultrasonic transducer is situated within the focusing chamber, said ultrasonic transducer optionally being situated on a cone-shaped body in turn situated on a pivotable bar within the focusing chamber. In this manner it is possible to localize a stone by means of an ultrasonic scanner without the ultrasonic transducer in question being damaged by shock waves. Excerpt(s): The invention relates to a device for disintegrating stones by means of a focusing chamber being part of an ellipsoid, preferably a rotation ellipsoid, and comprising in one focal point a spark gap producing shock waves.... In connection with one of the known devices the patient is situated in a tub containing water transmitting the shock waves.... According to a second device the tub is avoided by the focusing chamber being filled with water and covered by a thin membrane. This membrane abuts the skin of the patient, see, for example, DE-OS No. 3,146,626. Web site: http://www.delphion.com/details?pn=US04844081__

Kidney stone retriever Inventor(s): Duthoy; Everette J. (1472 Cherry Hill Rd., St. Paul, MN 55118) Assignee(s): none reported Patent Number: 4,625,726 Date filed: August 7, 1984 Abstract: The present invention is directed to a kidney stone retrieval device which includes a basket between a ferrule and a tube. Both the tube and the ferrule have aligned passages for receiving a guide wire. In this way, the guide wire may be inserted into a ureter past the stone so that the retrieval device may be pushed along the guide wire until the basket reaches and passes the stone, whereupon the device is maneuvered for dislodging and retrieving the stone with the basket. Excerpt(s): The present invention is directed to the general field of urology and, more particularly, to a device for dislodging and capturing a stone from a person's ureter.... Waste body fluids flow from the kidney through the ureter to the bladder. The fluids pass from the bladder through the urethra to exit a person's body. A blockage occasionally forms in the ureter of some people. The blockage is usually comprised of a hard stone-like material called calculus. Such a blockage can be painful and dangerous since it restricts the flow of waste fluids through the ureter. Ureteral calculus, more commonly known as a kidney stone, may be removed surgically. It is preferable, however, to try to capture the stone and pull it through the ureter, baldder and urethra. Devices and procedures for such capture and removal are, thus, known.... The most common stone retriever device is made from a cable having a wire basket at one end of the cable with a relatively short, somewhat flexible, rod-like end member, called a filiform, at the end of the basket opposite the cable. The basket is usually made of four equally spaced-apart wires which are sufficiently rigid to hold a large V-shape. The filiform of the device is inserted into the ureter and worked past the stone. As the basket is maneuvered alongside the stone, the stone moves into the space surrounded by the wires and is hopefully captured for removal on removal of the cable and basket. The problem with this device is that it is extremely difficult to work the basket around or even with the stone in order to capture the stone. Consequently, the removal procedure may be time consuming and is prone to failure. Web site: http://www.delphion.com/details?pn=US04625726__

Kidney stone specimen collection system Inventor(s): Newman; Dennis (3519 Grennoch, Houston, TX 77025), Stein; Ronald B. (8810 Weymouth Dr., Houston, TX 77031) Assignee(s): none reported Patent Number: 5,762,071 Date filed: September 4, 1996 Abstract: A kidney stone specimen collection device having a tubular body with a longitudinal axis, a mesh screen affixed to an interior of the tubular body and extending transverse to a longitudinal axis of the tubular body, a first closure member affixed to one end of the tubular body so as to selectively seal the end of the tubular body, and a second closure member affixed to an opposite end of the tubular body for selectively sealing the opposite end of the tubular body. The tubular body is formed of an impact-
86 Kidney Stones
resistant generally transparent plastic material. A flow indicator is positioned on a surface of the tubular body so as to be indicative of a direction of urine flow through the tubular body. Excerpt(s): The present application is a utility patent application which is based on U.S. Provisional patent application Ser. No. 60/009,260, filed on Dec. 26, 1995, and entitled "KIDNEY STONE SPECIMEN COLLECTION SYSTEM", presently pending.... The present invention relates to devices for the collection of kidney stones from a urine stream. More particularly, the present invention relates to containers for the receipt and capture of kidney stones.... It is a well known fact, at least to those of the medical profession, that there are hundreds of thousands of people in this country chronically or critically suffering from kidney stone afflictions. The patient is often advised to retrieve the foreign particles for purposes of clinical examination. This presents an obvious problem of inconvenience and perhaps embarrassment, particularly when it is impossible to have ordinary suitable household utensils at hand for the required purpose.

(Durham, NC) Assignee(s): Duke University (Durham, NC) Patent Number: 4,892,089 Date filed: February 23, 1989 Abstract: A method for comminuting kidney stones including treating a stone to be comminuted with a renal matrix-attacking substance and applying acoustic impulses to the stone so as to pulverize the stone into fragments small enough to be passed through the ureter and urethra. Excerpt(s): This invention relates generally to a method for comminuting kidney stones utilizing acoustic impulses, and more specifically to a treatment method which enhances the pulverizing effect of extracorporeal shock wave lithotripsy.... Kidney stones, also known as renal calculi, develop within the kidney and are in many cases too large to pass through the ureter and urethra. The stones are composed of both organic and inorganic materials. The inorganic components comprise most of the mass of the stone and are typically rigid crystalline masses of calcium or magnesium oxalates, phosphates, or various urates. The inorganic components ar different for each particular type of stone and therefore each stone may have different characteristics depending on the composition of its inorganic component.... The organic component of the stone is called the organic matrix (or renal matrix) and often forms an intricate mesh from the surface of the stone to the center of the stone. Although the organic component often comprises a small percentage (approximately 3% to 6%) of the entire kidney stone, it forms a mesh that extends throughout the stone and can be viewed as a "backbone" of the stone. The matrix composition is essentially the same in each urinary stone and typically comprises about 64% protein, 9.6% non-amino sugar, 5% glucosamine, and 10% bond water. The remainder of the matrix composition is inorganic ash composed mainly of calcium and various phosphates. Web site: http://www.delphion.com/details?pn=US04892089__

Method for treating kidney stones Inventor(s): Imondi; Anthony R. (Doylestown, PA), Wolgemuth; Richard L. (Hatfield, PA) Assignee(s): Warren-Teed Laboratories, Inc. (Columbus, OH) Patent Number: 4,143,130 Date filed: August 29, 1977 Abstract: Water soluble and colloidially water soluble polymers of carboxylic acidcontaining monomers useful for treating kidney stones are disclosed. Excerpt(s): This invention relates to pharmaceutical compositions containing soluble and colloidally water soluble carboxylic acid polymers and to methods of using them to treat kidney stones. Biological studies employing rats as the test animal show that the compositions of this invention are useful in binding calcium and dissolving kidney stones.... In the United States alone, there are each year about 250,000 newly diagnosed patients with all types of kidney stones. Analysis of these stones shows that 70% of all kidney calculi contain calcium. Although there is no unanimously accepted regimen for urolthiasis, reduction in urinary calcium excretion is one means of ston prophylaxis.... Highly substituted sodium cellulose phosphate is presently being studied clinically and appears to be useful in the treatment for calcium calculi (Pak, et al., New England J. Med. 290:4 (1974)). This material also binds intestinal calcium. The increase in fecal calcium with sequestrant therapy is accompanied by lower urinary calcium output. In essence, by increasing the fecal calcium load, calcium sequestrants decrease the calcium load on the kidney. Web site: http://www.delphion.com/details?pn=US04143130__

Non-invasive destruction of kidney stones Inventor(s): Nowacki; Christopher (Arlington Heights, IL), Brisson; Alfred G. (Schaumburg, IL), Shene; William R. (Plattsburgh, NY) Assignee(s): Trutek Research, Inc. (Lake Zurich, IL) Patent Number: 4,696,299 Date filed: April 3, 1986 Abstract: Apparatus for the non-invasive disintegration of kidney stones and the like. An ellipsoidal reflector open at one end is positionable against the body, and may have a diaphragm across the opened end to prevent leakage of water contained in the reflector. A spark gap is located at the first focal point of the ellipsoid, and sonic aiming means is physically interconnected with the ellipsoid for aiming the ellipsoid at the kidney stone or the like to locate the kidney stone at the second focal point of the ellipsoid. A series of sparks discharged across the spark gap generates a succession of shock waves that travel through water in the reflector, and through the body to impinge on the kidney stone or the like and thereby to disintegrate the same. Excerpt(s): Kidney stones, and also naturally occuring stones in the bladder and the ureter can be exquisitely painful, and often require surgical relief. Excision or destruction of stones in the bladder and sometimes in the ureter can be relatively easily accomplished but removal of stones from the kidney is a major procedure.... Removal of stones from the kidney is a very serious and traumatic surgical procedure. A large incision is made in the body. The kidney is essentially removed from the body and cut

open. The stone or stones are then removed, whereupon the kidney is sutured and returned to the body, with the body then being sutured.... Chemotherapy is available as a non-invasive therapy for uric acid stones. In this therapy the urine is alkalized. The existing stone thus is dissolved over a substantial period of time, and in most cases the patient can be cured before his condition becomes acute. However, the patient's condition is often already acute when the stone is discovered, and immediate surgery is imperative. Attempts at chemical dissolution of other types of stones have not been successful. Web site: http://www.delphion.com/details?pn=US04696299__ ·
Phantom kidney stone system Inventor(s): Schafer; Mark E. (Blue Bell, PA) Assignee(s): International Sonic Technologies (Horsham, PA) Patent Number: 5,014,686 Date filed: August 31, 1989 Abstract: The phantom kidney stone system for use with a commercial lithotripsy system includes a phantom kidney stone which simulates a human kidney stone and is suspended into the field of operation of the commerical lithotripsy system. The system also includes a trigger which is connected to receive a shock wave signal from the lithotripter which is representative of a shock wave output from the lithotripter. The trigger generates a trigger signal in response to the signal from the lithotripter. A counter is connected to receive the trigger signal and counts the number of trigger signals which is representative of the number of shock waves output from the lithotripter. A detection circuit is connected to the phantom kidney stone and produces a signal proportional to the detected size of the stone at a given point in time and compares the detected size of the stone to a predetermined reference size indicative of a condition wherein the stone would be crushed. The detection circuit generates an output signal at a time when the detected size of the stone is less than the reference size. A processor is connected to receive the output signal from the detection circuit and is connected tothe counter and outputs the number of trigger signals which were counted by the counter at a time when the detection circuit generates the output signal. A display indicated the number to the user of the lithotripter. Excerpt(s): The present invention relates to a phantom kidney stone system for use with a commercial lithotripsy system.... Currently there is no uniformly repeatable test procedure which can be used by manufacturers and/or users of commercial lithotripsy systems for quality control purposes in order to ascertain that the lithotripsy system is functioning properly.... Also, there is no uniformly repeatable test procedure which can be used to train operators of commercial lithotripsy systems to improve the accuracy with which the operators perform an actual lithotripsy operation. There is a need for the operators to be trained properly so that when an actual lithotripsy operation is performed, the lowest possible number of shock waves are used to break up the kidney stone. It is necessary to keep the number of shock waves which are input into human tissue as low as possible. Therefore, operators should be trained prior to performing an actual lithotripsy operation on a human patient. At the present time, the operators do not have an opportunity to work with the lithotripsy system until they actually use the equipment on a human patient.

Pleated diaphragm for coupling kidney stone disintegrator to human body Inventor(s): Dela-Cruz; Exequiel (Arlington Heights, IL), Nowacki; Christopher (Arlington Heights, IL), Brisson; Alfred G. (Kildeer, IL) Assignee(s): Trutek Research, Inc. (Lake Zurich, IL) Patent Number: 4,745,921 Date filed: December 23, 1986 Abstract: An extracorporeal kidney stone disintegrator comprises an ellipsoidal reflector having an open end. A spark gap is positioned in said reflector at the first focus point thereof. A flexible cap closes the otherwise open end of said reflector, and a body of liquid fills said reflector and said cap. The cap is adapted for disposition against a human body having therein a concretion such as a kidney stone to be disintegrated. The reflector is positioned so that the concretion lies on the second focus point of the reflector. Generation of a spark across said spark gap causes generation of a shock wave focused on the concretion and coupled to the concretion by the body of liquid and the tissues of the body through the cap. The cap has an annular pleat enhancing flexibility of the cap.

Kidney stone collection device and method Inventor(s): Phan, Cu Ngoc; (Newport Coast, CA), Tran, Khiem Thanh; (Newport Coast, CA) Correspondence: HAYNES BEFFEL & WOLFELD LLP; P O BOX 366; HALF MOON BAY; CA; 94019; US Patent Application Number: 20030060787 Date filed: August 13, 2002 Abstract: A kidney stone collection device includes entrance and settling chambers coupled at a junction, an inlet opening into the entrance chamber, and an outlet conduit including the device outlet. The outlet conduit also has outlet conduit entrance which opens into the settling chamber. The device includes a base defining the bottom of the settling chamber when the body is in an upright orientation. The outlet conduit entrance is at a higher elevation than at least a portion of the base when the body is in the upright orientation. The body may be made of a pliable and/or transparent material so that the user may see and/or feel kidney stones collected at the base. A shape-maintaining frame element may be used at the inlet to permit the inlet to be maintained in an open configuration. Excerpt(s): This application claims the benefit of provisional patent application No. 60/______ filed on ______ Sep. 2001 and entitled Device/Apparatus and Method to Collect Kidney Stones or Stone Fragments from Urine.... The presence of upper urinary tract stones, commonly referred to as kidney stones, is a common medical problem. Fortunately, kidney stones can be effectively treated with extracorporeal shockwave

lithotripsy. This is a relatively noninvasive technique during which kidney stones are fragmented by shockwaves applied to the skin surface. The stone fragments can then be passed along with urine via urination. Very small stones may be passed spontaneously without lithotripsy. However, it is a very important to collect the kidney stones and stone fragments for analysis and so that the physician can have the composition determined and then prescribe appropriate medication or other treatment to prevent stone recurrence. Stones and stone fragments will usually be referred to collectively as stones.... FIGS. 1 and 2 illustrate two different devices 10, 12 currently used to collect stones. Collection device 10 is a conical device typically having a paper or plastic body 14 with a net or mesh 16, or other filtering medium, at the lower end. Device 12 is a telescoping, collapsible-cup type device having a net or mesh 18 at the bottom of the device. The body 20 of device 12 is typically made of plastic. These conventional devices work on the filtration principle. Urine is introduced into the device and the net or mesh, or other filtering medium, is supposed to catch the stones. However these devices have some disadvantages. It is sometimes difficult to determine if there are stones or stone fragments caught by the filtering medium. There are often blood clots in the urine of patients with kidney stones. These blood clots may cover stone fragments. The patient may have to use his or her fingers to squeeze the blood clots to see if there stone fragments inside them, an unpleasant task. Very small stone fragments may pass through the filtering medium. In addition, very small stone fragments are often difficult to remove from the filtering medium. The device may be large and inconvenient to carry around; this may discourage patients from collecting stones when away from home. The device may also be relatively expensive.

Methods and devices for the in situ dissolution of renal calculi Inventor(s): Constantz, Brent R. (Menlo Park, CA) Correspondence: BOZICEVIC, FIELD & FRANCIS LLP; 200 MIDDLEFIELD RD; SUITE 200; MENLO PARK; CA; 94025; US Patent Application Number: 20030178030 Date filed: March 20, 2002 Abstract: Methods and devices for at least reducing the mass of, if not dissolving, renal calculi in situ are provided. In the subject methods, a renal calculus is contacted, e.g. flushed, with an acidic dissolution solution in situ, where the acidic dissolution solution is a solution of a strong, inorganic acid, e.g. hydrochloric acid. In many embodiments, the renal calculus is first enclosed in an isolated local environment of a device prior contact with the dissolution solution. Also provided are novel devices and kits for practicing the subject invention. Excerpt(s): The field of this invention is nephrolithiasis and the treatment thereof.... Nephrolithiasis, also known as urolithiasis or urinary tract stone disease, is the term used to refer to the condition in which renal calculi or kidney stones occupy one or more locations in the urinary tract, e.g. major calices, minor calices, renal pelvis, ureter, etc. Renal calculi or kidney stones spontaneously develop in the ureter and can cause significant health problems, including pain, bleeding, blockage of the ureter, etc.... A number of different types of kidney stones can form in the urinary tract. Approximately 75 to 85% of all stones are calcium stones, which are typically made up of calcium oxalate and/or calcium phosphate, where the calcium phosphate is typically hydroxyapatite or brushite. Uric acid stone are stones made up of crystallized uric acid

who needs to take medications, choosing a health care provider, how to stay motivated, and how to modify one's diet and stay stone free. The authors emphasize that one of the more difficult aspects of preventing stone disease is keeping patients motivated. However, if patients can learn about the physiological causes of stones and really understand the background of dietary restrictions, they will be more successful overall in preventing recurrence. The book includes 25 chapters, an appendix of useful tables, an appendix of food diaries, a glossary of terms (which are italicized in the text), a bibliography, and a subject index. 25 references. ·

This chapter on the different types of kidney stones is from a book that offers readers a program designed to prevent the recurrence of kidney stones. The authors review essential lifestyle and diet changes and the latest medical research, and offer specific guidelines for both men and women. In this chapter, the authors describe calcium oxalate stones (75 percent of stones are this type), uric acid stones (10 percent), struvite or infected stones (10 percent), and cystine stones (1 percent); stones can also have a combination of these elements. For each type of stone, the authors note the causes, related diseases and medical conditions, complications (notably struvite layered on other types of stones), and risk factors (including in children). The chapter concludes with a discussion of bladder stones and the importance of stone analysis. Knowing the exact composition of a stone gives the doctor an important clue as to the reasons why the stone has formed; treatment strategies (including specific dietary modifications) can then be individualized and their success made more likely.

painful is from a book that offers readers a program designed to prevent the recurrence of kidney stones. The authors review essential lifestyle and diet changes and the latest medical research, and offer specific guidelines for both men and women. In this chapter, the authors describe the two kinds of pain that people experience when passing stones (soreness of the kidney and colic), three types of basic renal colic pain patterns (ureteropelvic stone, midureteral stone, low ureteral stone), three common places where stones can stop moving (pelvis of kidney, iliac artery or branch of the aorta, or bladder tunnel), the secondary symptoms of passing a kidney stone (vomiting, fever and chills, blood in the urine), the importance of getting an accurate diagnosis of renal colic, options for treating the pain, and when hospitalization is indicated. The authors emphasize that when a patient is having an episode of renal colic and then the pain stops, it does not necessarily mean that the stone is out. A stone stuck midureter can stop hurting, but it can eventually cause trouble to the kidney. Patients should always consult a physician after a stone episode or a suspected stone episode. 1 figure. ·

Summary: Kidney stones occur when there are too many waste products or not enough fluid to flush those waste products out; the waste comes together to form a 'stone.' When the kidneys then eliminate these stones, the pain can be excruciating. This introductory chapter is from a book that offers readers a program designed to prevent the recurrence of kidney stones. The authors review essential lifestyle and diet changes and the latest medical research, and offer specific guidelines for both men and women. In this chapter, the authors review the physiology of kidney stones, why they happen, and why they seem to be becoming more prevalent. The authors note that, since World War II, the incidence of stone disease has been increasing dramatically in the Western industrialized nations; this is connected directly to the prevalence of a richer diet. After years of trying to find medicines that would cure stones, doctors found that two thirds of patients seen with recurring stones stopped making them by following basic dietary advice. The authors of this chapter contend that only a handful of patients need to take medication to prevent recurrence, if they closely follow dietary recommendations. The guidelines stress a two part approach to prevention: understanding how and why stones form, and then targeting the specific dietary and lifestyle changes that will prevent stone disease. The author concludes by encouraging patients to make the commitment to preventing further kidney stones.

calculi. Four sections cover the incidence and epidemiology of renal calculi; the clinical features; the types of calculi, including composition and formation; and the evaluation of patients with nephrolithiasis. The author stresses that nephrolithiasis should be considered a symptom; a systematic approach to investigation and management of possible underlying conditions should be the aim of the practicing pediatrician.

Summary: The chance of a person forming kidney stones is largely determined by their genetic makeup and by the way their diet and lifestyle interplay with this genetic inheritance. This chapter on how and why kidney stones form is from a book that offers readers a program designed to prevent the recurrence of kidney stones. The authors review essential lifestyle and diet changes and the latest medical research, and offer specific guidelines for both men and women. In this chapter, the authors stress that it is important to understand the basic factors that encourage the formation of urinary crystals. With this understanding, patients can better prevent recurrence of their kidney stone problems. Using the metaphor of making rock candy out of super saturated sugar water, the authors describe how crystals form and how to discourage their formation. Topics include the composition of kidney stones (notably calcium oxalate, a salt), the conditions that favor crystal formation, the best inhibitor of kidney stones, and how uric acid stones are formed. The authors note that there is a genetic tendency to form stones, but diet and fluid intake also make a big difference in whether or not the gene that controls stone formation can assert itself. 1 figure.

This chapter on the most common of these lifestyle factors is from a book that offers readers a program designed to prevent the recurrence of kidney stones. The authors review essential lifestyle and diet changes and the latest medical research, and offer specific guidelines for both men and women. In this chapter, the authors discuss the lifestyle factors that may contribute to stone disease, including bathroom access, situations that make the person lose fluids (like extra exercise, or high heat environments), ultraviolet (UV) light exposure, eating patterns, and changes in lifestyle. The authors discuss each of these factors, offering short vignettes of patients' lifestyles to illustrate the concept presented. The authors conclude that although it is not always possible to separate dietary and lifestyle factors, there are many stone formers who must look as closely at the way they live and the things they do as at their diet.

Website: www.readerndex.com/fourgeez. PRICE: $17.95 plus shipping and handling. ISBN: 0963706861. Summary: This chapter of common questions and answers about kidney stones is from a patient education handbook that describes how virtually every patient who follows treatment based on appropriate testing, proper interpretation, and sound medical principles can substantially reduce or eliminate all future kidney stone production. The authors emphasize the need for patients to educate themselves and to take a proactive approach to preventing new stones, in many cases to the point of educating their physicians and demanding appropriate diagnostic and treatment methods. Topics covered in this chapter include why kidney stone pain attacks hurt so much, the use of stents, indications for surgery, the chances for recurrence, dissolution therapy (dissolving the stone with medication), how to manage a kidney stone attack, the use of lithotripsy (the 'stone machine') to break up kidney stones, risk factors or other occupational considerations, dietary and food suggestions to help prevent stones (increasing fluids, limiting salt and meat proteins), other ways to prevent stone recurrence, metabolic testing for stone prevention, and the most common problems found in metabolic testing. The authors stress that the first essential step in the prevention of kidney stones is to guarantee that there will always be sufficient water intake to produce enough urine to easily dissolve all the minerals and chemicals the kidneys normally produce and excrete.

ISBN: 0963706861. Summary: This chapter on the diagnosis of kidney stones is from a patient education handbook that describes how virtually every patient who follows treatment based on appropriate testing, proper interpretation, and sound medical principles can substantially reduce or eliminate all future kidney stone production. The authors emphasize the need for patients to educate themselves and to take a proactive approach to preventing new stones, in many cases to the point of educating their physicians and demanding appropriate diagnostic and treatment methods. Every patient with a possible kidney stone requires some type of imaging study of the urinary tract. This chapter describes the imaging tests used to confirm the presence of a kidney stone, including ultrasound, intravenous pyelogram (IVP), retrograde pyelograms, CT (computed tomography) scans, flat plate or KUB (kidneys, ureters, and bladder), and plain renal tomograms (a type of x-ray). For each type of diagnostic technique, the authors explain the indications for the test, the types of images or results that can be obtained, and what the patient can expect during the testing procedure. The authors conclude that with one or more of these imaging techniques, it should be possible to correctly identify any and all stones that might be present in the urinary system.

[email protected]. Summary: Sarcoidosis is a chronic, progressive systemic granulomatous (causing lesions) disease of unknown cause (etiology), involving almost any organ or tissue, including the skin, lungs, lymph nodes, liver, spleen, eyes, and small bones of the hands or feet. This brief article, from a newsletter for patients with sarcoidosis, reviews kidney disease, its types, diagnosis, and management. The article begins with a summary of the anatomy and function of the kidneys, which filter the blood (removing waste and excess body fluids), and maintain the balance of some essential nutrients helping to regulate blood pressure, red blood cells, and elements such as potassium and calcium. Without functioning kidneys, one cannot live without dialysis, the mechanical filtration of the blood. Kidneys fail for a variety of reasons, including trauma to the kidney, toxins, heart failure, obstruction (kidney stones), overuse of some medications, and diseases that invade the kidney, such as sarcoidosis. Diabetes and high blood pressure are the most common causes for loss of kidney function. Warning signs of kidney disease are high blood pressure (hypertension), blood or protein in the urine, creatinine level greater than 1.2 in women or 1.4 in men, more frequent urination (especially at night), difficult or painful urination, and puffy eyes or swelling of the hands or feet (especially in children). Loss of kidney function can produce symptoms including fatigue, weakness, nausea, vomiting, diarrhea or constipation, headaches, loss of appetite, increased edema (fluid retention), and fever or chills. Kidney failure is characterized as acute kidney failure, chronic kidney insufficiency, and chronic kidney failure. The need to put a person on dialysis depends upon the levels of creatinine and urea nitrogen in the blood and the evaluation of body parameters such as fluid status, and symptoms of toxicity. The author encourages readers to practice preventive measures which include drinking 8 to 10 glasses of water per day, preventing or treating diabetes and high blood pressure, avoiding tobacco, eating a well balanced diet, practicing good hygiene, treating wounds and infections, limiting exposure to heavy metals and toxic chemicals, and avoiding unnecessary over the counter drug use.

Atchley Pavilion, 11 Floor, 161 Fort Washington Avenue, New York, NY 10032-3784. (212) 305-0111. Summary: This brief newsletter article describes the causes of kidney stones. There are four factors that lead to stone formation: urine saturation, crystallization, particle retention, and matrix foundation. The author first describes who is at risk for forming kidney stones and briefly outlines the different types of stones: calcium oxalate (75 percent of patients develop these), uric acid, and struvite stones. Urine saturation occurs when urine has excessive amounts of calcium, uric acid, and oxalate crystals, which are all stone-forming substances. This saturation may occur during the day but frequently occurs after meals or during the sleeping hours or hot weather because of the lack of fluids consumed. Stone inhibiting substances include pyrophosphate, citrate, magnesium, and nephrocalcin. Freshly voided urine from most healthy individuals contains small crystals, which are flushed out of the urinary tract. However, some people have anatomic abnormalities in the kidney and or ureter, making the crystals stick to the lining of these structures. In addition to being composed of crystals, stones are also formed from an organic material called matrix. Matrix acts as the foundation for stone formation by controlling crystallization. The matrix is composed of a carbohydrate and protein. The article concludes with a section on preventing kidney stones, offering the following suggestions: increase fluid intake to lower saturation; make sure one half the fluid intake is water; produce two and a half quarts of urine in 24 hours; avoid eating grapes, berries, plums and citrus fruits; limit intake of coffee, tea and chocolate; avoid eating sardines, shrimp, and oysters; and, to prevent uric acid stones, avoid eating liver, sweet breads, and brains. Some people may require medication because they form calcium and uric acid stones even though they have adequate fluid intake and do not consume an excessive amount of dairy products. 1 figure.

Kidney Stones: Often Painful, But Manageable Source: Mayo Clinic Health Letter. 20(4): 6. April 2002. Contact: Available from Mayo Clinic Health Letter. Subscription Services, P.O. Box 53889, Boulder, CO 80322-3889. (800) 333-9037 or (303) 604-1465. Summary: This brief newsletter article reviews the problem of kidney stones (nephrolithiasis) and their treatment. The author first reviews the different types of kidney stones, including calcium stones, uric acid stones, struvite stones, and cystine stones. The author cautions that kidney stones often first occur between the ages of 20 and 50 and tend to recur. Small stones may pass with little or no pain. Others can be quite painful as they pass through the narrow tubes that connect each kidney to the bladder (the ureters). Drinking plenty of fluids and staying physically active can help to move a stone through the patient's system. Stones that are too large to pass or that are causing bleeding, kidney damage, or ongoing urinary tract infection (UTI) may require surgical treatment. Stone removal techniques include extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy, and ureteroscopic stone removal. One sidebar reviews strategies to prevent future stones.

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for kidney stones. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DIÒ Advice for the PatientÒ can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with kidney stones. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Mosby’s Drug ConsultÔ Mosby’s Drug ConsultÔ database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.
PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html.
Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter,
116 Kidney Stones
Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.
Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to kidney stones by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “kidney stones” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for marketing, information on side effects can be found on the product’s label. If the product is not approved, you may need to contact the sponsor. The following is a list of orphan drugs currently listed in the NORD Orphan Drug Designation Database for kidney stones: ·
Succimer (trade name: Chemet) http://www.rarediseases.org/nord/search/nodd_full?code=169

Report on the Management of Staghorn Calculi Source: Baltimore, MD: American Urological Association. 1994. [54 p.]. Contact: Available from American Urological Association. 1120 North Charles Street, Baltimore, MD 21201. (410) 727-1100. Fax (410) 223-4370. E-mail:
[email protected]. Website: www.auanet.org. PRICE: Single copy free while supplies last; payment of postage required. Summary: This report offers recommendations to assist physicians specifically in the treatment of struvite staghorn calculi (kidney stones). Although relatively uncommon, these kidney stones present serious problems because they occur in the presence of urinary tract infections (UTI) and because the stones themselves are infected. Treatment must remove stones completely to eradicate all infected stone material. Accepted alternatives for treating patients with struvite staghorn calculi are grouped into five general modalities: watchful waiting, open surgery (referring to any method of open surgical exposure of the kidney and removal of stones), extracorporeal shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PNL, removal of the kidney stone through the skin), and combinations of PNL and SWL. As a standard, a newly diagnosed struvite staghorn calculus (stone) represents an indication for active treatment intervention. Patients must be informed about the relative benefits and risks associated with each of these treatments. As a guideline, PNL, followed by shock wave lithotripsy or repeat percutaneous procedures as warranted, should be utilized for most standard patients with struvite staghorn calculi. The report also summarizes the literature reviewed by the panel (in chart form), describes the methodology used, and includes a list of references and a subject index. 3 appendices. 15 figures. 19 tables. 151 references.

used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.21 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.22 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: ·
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
·
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
21
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story.
22 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on kidney stones can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to kidney stones. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly.
The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below.
Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to kidney stones. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “kidney stones”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on kidney stones. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/.

(800) 451-5797 or (717) 761-0216. Fax (717) 761-0216. PRICE: $0.75 each; plus shipping and handling; bulk copies available. Booklets must be ordered in quantities of 10. Order number: D28. Summary: About 5 percent of all kidney stones are uric acid or urate kidney stones. Certain diseases, such as gout, can lead to the formation of uric acid kidney stones. Normally, urine is slightly acid. The most important factor leading to the formation of uric acid stones is the production of urine that is too acid. This booklet outlines the recommended diet for people who have been treated for uric acid stones and want to prevent recurrence of the problem. Treatment to prevent uric acid stones is usually with medication which is used to raise the pH of urine (make it less acidic) and prevent stone formation. Dietary changes may help the medication raise and maintain the alkaline level of urine. The booklet outlines five strategies that include increasing fluid intake, incorporating alkaline-ash foods in the diet, monitoring protein intake (not exceeding the RDA for protein and sometimes limiting foods high in purines), avoiding certain medications (such as aspirin), and limiting the use of alcohol (which increases uric acid production). One chart lists foods with high, moderate, and low content of purine. Another chart lists foods that produce acid ash or alkaline ash, and foods that are neutral; foods are listed in categories of meats, fats, milk, starches, vegetables, fruits, sweets, and beverages. A final chart offers a sample menu for patients with uric acid stone formation tendencies. 3 tables.

Kidney Stones: Basic Facts About Kidney Stones. What Every Individual Should Know Source: Baltimore, MD: American Foundation for Urologic Disease. 200x. 16 p. Contact: Available from American Foundation for Urologic Disease (AFUD). 1128 North Charles Street, Baltimore, MD 21201. (800) 242-2383. Website: www.afud.org. PRICE: $13.00 for pack of 50; plus shipping and handling. Summary: Each year, roughly 500,000 Americans have kidney stones (nephrolithiasis) and over one third of those patients have to be hospitalized. This health education brochure describes kidney stones, risk factors for getting kidney stones, the tests that are used to diagnose problems with kidney stones, treatment options, and prevention strategies. The brochure begins with a six item pretest to determine the reader's knowledge of kidney stones. Early symptoms of kidney stones include an ache in the back and side, burning during urination, blood in the urine, frequent urge to urinate, nausea and vomiting, and a flank or lower abdomen that is sensitive (painful) to the touch. Kidney stones usually form because there is a breakdown in the balance of liquids and dissolved solids in the urine. Kidney stones tend to occur more frequently in men between the ages of 20 and 60 years old with a family history of stone formation.

The brochure defines and describes different types of stones, including calcium oxalate and phosphate, struvite (infection), uric acid, and cystine stones. Diagnostic tests can include x ray, ultrasound, and intravenous pyelogram (an x ray of the urinary system, assisted by an injection of dye). Treatment options focus on lithotripsy, which uses shock waves to disintegrate the kidney stone into fragments small enough to pass out of the body in the urine. Prevention strategies include drinking plenty of fluids, monitoring the color of one's urine (should be pale yellow), dietary modifications, and the use of some medications. The brochure concludes with a glossary of terms used in the text and the answers to the pretest. 2 figures. 1 table. ·

PRICE: Single Copy Free. Order No. 08-47. Summary: The cause, mechanism and clinical management of kidney stones are better understood today due to scientific progress. This leaflet defines and describes the mechanisms and causes of stone formation, the symptoms due to pressure of a stone, diagnosis and treatment. A diagram shows the location of stones in the urinary tract. The formation of a kidney stone and the resulting obstruction may be related to age, sex, activity, climate, water intake, metabolic disturbances, misuse of medications, urinary infection and stagnation. A new treatment, extracorporeal shock wave lithotripsy (ESWL) is an example of a non-surgical technique being used to remove kidney stones. There are effective treatments that can possibly prevent stone formation in all situations where stones are formed.

Summary: The function of the kidneys is to filter chemicals that the body does not need out of the blood. Under certain conditions, chemicals in the urine may form crystals, which build up and stick together to form kidney stones (lithiasis). Kidney stones may block the flow of urine through the urinary tract, causing severe pain. This patient education brochure describes kidney stones and the use of lithotripsy (extracorporeal shock wave lithotripsy, or ESWL) to treat them. Lithotripsy is a method of crushing a kidney stone while it is still inside the patient's body. During lithotripsy, carefully directed shock waves pass harmlessly through the patient's body and hit the stone, causing it to crumble into sandlike particles. These particles can then pass easily out of the urinary tract. Complications of lithotripsy are rare but can include infection, bleeding of the kidney, bruising of the kidney or skin, obstruction of the ureter (the passageway from the kidney to the bladder), or failure of the stone to fragment. The brochure describes what patients can expect during and after the procedure and reminds readers when to contact the physician. The brochure concludes with a section outlining the recommended steps for preventing future kidney stones, including drinking lots of water, following the diet recommended by the health care provider, taking prescribed medications, and attending regular followup visits. The brochure is illustrated with full color line drawings. 7 figures.

Summary: This fact sheet reviews the problem of kidney stones (urolithiasis) in adults. A common problem, occurring in an estimated 10 percent of people in the United States, kidney stones will often pass out of the body without any intervention by a physician. Stones that cause lasting symptoms or other complications may be treated by various techniques, most of which do not involve major surgery. Research advances have led to a better understanding of the many factors that promote stone formation. The fact sheet first reviews the anatomy and physiology of the urinary tract and kidneys, then defines a kidney stone as a hard mass developed from crystals that separate from the urine and build up on the inner surfaces of the kidney. Certain foods may promote stone formation in people who are susceptible, and a person with a family history of kidney stones may be more likely to develop stones. Urinary tract infections, kidney disorders such as cystic kidney diseases, and metabolic disorders such as hyperparathyroidism are also linked to stone formation. The fact sheet reviews the symptoms and diagnosis of kidney stones, then describes treatment options, focusing on prevention for people at risk. Treatment options described include drug therapy, surgery, extracorporeal shockwave lithotripsy (ESWL), percutaneous nephrolithotomy, and ureteroscopic stone removal. The fact sheet concludes with a brief list of current research strategies in this area, a list of suggested readings, and prevention points to remember. The fact sheet lists resource organizations for readers who wish to obtain additional information about kidney stones, hyperparathyroidism, and gout. A brief description of the National Kidney and Urologic Diseases Information Clearinghouse (NKUDIC) is also provided. 6 figures. 5 references. ·

Passing a Kidney Stone Source: Patient Care. 33(15): 44. September 30, 1999. Contact: Available from Medical Economics. 5 Paragon Drive, Montvale, NJ 07645. (800) 432-4570. Fax (201) 573-4956. Summary: This patient education fact sheet offers information about passing a kidney stone. Kidney stones are tiny, hard objects, usually made from calcium. Although the pain involved in passing a kidney stone can make them feel large, most kidney stones are as small as a grain of sand. Kidney stones do not do much harm in the kidneys; however, they can cause great pain if they drop from the kidney into the ureter (the tube that brings urine from the kidney to the bladder). Kidney stones can form when the patient does not drink enough fluids; if the urine is yellow, the person is not drinking enough (urine should be almost clear). Stones can also form when there is too much or too little of certain substances in the urine; diet and genes are two of many possible causes. Most of the time, stones pass out on their own in the urine. Most stones pass in a few hours, but some take a few days. The fact sheet describes how to catch the stone by urinating through a fine strainer or coffee filter paper; the stone can then be taken to the physician for testing. This can help the physician decide how best to prevent future stones. If the stone does not pass in a few days, lithotripsy may be needed. The lithotripsy procedure breaks the stones into tiny pieces that will pass more easily. The fact sheet concludes by encouraging readers to drink 10 glasses of water (10 ounces

each) every day. The fact sheet also leaves blank space for patient notes or physician instructions. 1 figure. ·

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.23
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
