Kidney Stones Clinical Trials

The purpose of the study is to determine if increased fluid intake will result in decreased risk of stone formation. This study will last 2 years. There are up to 3 study visits. There will be 24-hour urine collections, CT scans, and specimen collection. Risks and benefits will be discussed ...

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 ...

Summary Purpose and Objective: The purpose of this study is to test the feasibility of rapid acquisition of point of care 3D ultrasound in obtaining abdominal and/or pelvic images. The study will use a newly developed acquisition method and post-processing technique to create three dimensional image models of the abdomen ...

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 ...

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 ...

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 ...

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 ...

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 ...

The objective of this study is multi-site, standardized observation and characterization of kidney stone patients. Furthermore, an adequate structure should be established for the execution of studies with kidney stone patients, in order to then, if necessary, develop recommendations for useful monitoring or prophylactic measures, as well as new treatment ...

Background: Percutaneous nephrolithotomy (PCNL) is generally performed under general or neuraxial anesthesia. The investigators have reported three patients who were at high risk of both general anesthesia and neuraxial anesthesia received percutaneous nephrolithotomy with ultrasound guided paravertebral block. ThenThe investigators performed ultrasound guided paravertebral block for 45 patients who received ...
