Calcium Supplements Strategy for Kidney Stones Prevention in Crohn's Patients

The primary objective of this study is to establish optimal oral calcium supplementation in Crohn's patients who have had an ileal bowel resection. This population is at high risk for calcium oxalate kidney stones, a direct consequence of extensive gut malabsorption and enteric hyperoxaluria. The benefit of providing oral calcium ...

Phase N/A

Investigate the Renal Movement by Single Lung Ventilation in Patients Administered RIRS for Kidney Stones.

In recent years open surgical treatment has changed to minimal invasive treatments for kidney stone treatment. Additionally, the treatment choices vary depending on the localization of the stone and its dimensions. In the European Urology Association (EUA) guidelines, it states the RIRS method can be used to treat stones up ...

Phase N/A

Randall's Plaque Study: Pathogenesis and Relationship to Nephrolithiasis

In order to attempt to explain the pathogenesis of renal calculi, the investigators videotape and document the location and characteristics of each stone, papillae and calyces. One or more small papillary biopsies are taken for analysis to help determine the point of origin of the kidney stone and histological studies ...

Phase N/A

Trial Comparing Relapse Rates Between Standard Ureteroscopic Removal Of Ureteral Stone And Standard Removal With Additional Ureterorenic Clearing Of Non-Symptomatic Stones In The Kidney

Patients with a ureteral (the tube that leads from the kidney to the bladder) stone often also have small stones in the kidney (frequently visible on CT). If these small kidney stones are determined to be asymptomatic (not causing any problems or pain), then most urologists will simply remove the ...

Phase N/A


Prospectively randomized study in patients with renal pelvic stones who are candidate to standard PCNL procedure. One to one, controlled clinical trial. Patients will be randomly allocated into two groups, 20 patients in each group. Group A will be scheduled to receive routine standard PCNL. Group B will be scheduled ...

Phase N/A

Struvite Stones Antibiotic Study

Struvite stones or infection stones are a subset of kidney stones that are related to bacterial infection. They only make up 15% of all kidney stones, but account for a much higher percentage of mortality (up to 67%) compared to other stonesdue to the infectious component. Treatment is to ensure ...


Trial of Randomized Antibiotic Administration in Percutaneous Nephrolithotomy

For large renal stone burdens and/or complex stones, Percutaneous Nephrolithotomy (PCNL) has become the mainstay for treatment, replacing open kidney stone surgery since it's introduction in 1976. However, PCNL is not without its complications, specifically infectious. The procedure carries up to 25% incidence of infectious complications with approximately 1% rate ...


Night Time Use of Thiazide Diuretics for Improved Reduction in Stone Risk in Stone Formers With Elevated Urine Calcium

The study will be divided into three phases for every single patient, investigators will study 15-20 stone formers who have previously documented elevated urine calcium excretion, with a plan to measure their urine chemistries at baseline (if they currently use thiazide diuretics, they will come off of their respective thiazide ...

Phase N/A

Safety and Clinical Efficiency of the 21-day Fasting-like Diet in Patients With Metabolic and Autoimmune Diseases

Although fasting has been proved an effective approach to treat metabolic and autoimmune diseases in mice, prolonged fasting is difficult to implement in human-beings for the safety and feasibility reasons. In this clinical trial, we will recruit metabolic and autoimmune diseases and then follow a traditional Chinese 21-day fasting-like diet ...


Comparison of Multiple- Single- and Zero-dose of Ciprofloxacin Prophylaxis in Retrograde Intrarenal Surgery

PURPOSE To compare multiple-, single-, zero-dose antibiotic prophylaxis for retrograde intrarenal surgery (RIRS) and detect the ideal regimen to prevent systemic inflammatory response syndrome (SIRS). METHODS An error of 5% and a power of 80% were assumed to detect a 14.9% difference in rates of postoperative SIRS (5.1% for the ...
