Quality of Life in Patients With Double Loop Ureteral Stent (JJ Silicone Hydrogel Study)

- The double loop stents are used for both prevention and treatment of ureteral obstruction: They permit the interim internal bypass drainage of urine when obstruction in the ureter especially in cases of lithiasis or after surgical intervention on the upper urinary tract. - There are many indications for double ...


Does Treatment With Alfuzosin Increase Success Rates of (SWL) Shock Wave Lithotripsy

All patients undergoing SWL are included in study. Exclusion criteria: Patient with radio-lucent stone, patients treated with calcium channel blockers, alpha blockers, steroids, patients with contraindication to alpha blocker treatment, postural hypotension patents with abnormal liver function tests. Patient will be recruited to the study prospectively. Following signature on inform ...


Is There is a Role of Prophylactic Therapy With Tamsulosin Before Extracorporeal Shock Wave Lithotripsy to Avoid Development of Steinstrasse ?

The purpose of this study is to determine if there is a role of prophylactic therapy with tamsulosin prior extracorporeal shock wave lithotripsy to avoid development of steinstrasse. 150 persons that will go to Extracorporeal shock wave lithotripsy will randomize to 2 groups. Group 1 -of 75 persons will recieve ...

Phase N/A

Alfuzosin for Medical Expulsion Therapy of Ureteral Stones

Patients presenting to Naval Medical Center San Diego with symptomatic ureteral stones visible on CT and KUB, and who are medically stable will be offered enrollment. Upon consent, patients will be randomly assigned to one of four outpatient treatment arms, randomized 1:1:1:1 and include; Group 1 - Alfuzosin 10 mg ...


Effect of Dietary Sodium and Potassium Citrate on Renal Mineral Handling

This study intends to characterize the affect of sodium and potassium citrate in the diet on renal function.

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 ...


Indwelling Stent Discoloration Project

The aim of this study is to identify the root cause for the significant discolouration of Boston Scientific Percuflex based stents observed in some patients, particularly those from Japan.

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

Evaluation of Kidney Function by Multi-modal Magnetic Resonance Imaging and Spectroscopy

Early and specific detection of dysfunction in kidney diseases and differential diagnosis of potential complications in the renal allograft are fundamental to initiate appropriate treatment. In addition, determination of renal function may reveal physiological mechanisms that may prove useful for future therapeutic procedures. Currently, used methods to access renal function ...

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 ...
