Active clinical trials for "Nephrolithiasis"

The primary purpose of this study is to evaluate the effect of lumasiran on the percent change in urinary oxalate excretion in patients with recurrent calcium oxalate kidney stone disease.

Purpose: The purpose of the Stone Centre Serum and Urine Bank is to provide researchers with large numbers of serum and urine samples from kidney stone patients and controls for study of stone disease detection and treatment, and will take into account different genetic backgrounds, ages, and other patient factors to provide a broad sample size for the study of stone disease The Serum and Urine Bank will undoubtedly be an invaluable tool in the quest to understanding urinary stone disease. Objective: The objective of this research is to identify protein species or other compounds responsible for or contributing to kidney stone initiation and propagation.

The purpose of this study is to evaluate the efficacy of MP-5971 in facilitating stone passage after Shock Wave Lithotripsy treatment.

Obstructing urolithiasis can be life-threatening in the setting of urinary tract infection. The purpose of this study is to identify and validate risk factors and markers for the presence of infection and development of sepsis among patients with obstructing urolithiasis.

This is a randomized control trial (meaning the selection is random as when flipping a coin) to assess the benefit of paravertebral blockade (PVB) in Percutaneous nephrolithotomy/nephrolithotripsy (PCNL) surgery.

Intrarenal calcifications (nephrocalcinosis) is present in Dent's disease and likely contribute to progression toward renal failure. In order to prevent this complication it is usually proposed to treat affected patients during childhood with high doses of thiazides.

The goal of this proposal is to determine the contribution and significance of obesity to urinary oxalate excretion and thus calcium oxalate kidney stone disease. Successful completion of the study will provide insight into the link between obesity and kidney stone disease and should identify future strategies to treat this disease.

The objectives of this post-market evaluation are to assess the capacity of the procedure to be completed with use of only a semi-rigid ureteroscope, without requiring use of a flexible ureteroscope to compare the rate of retropulsion and the time required to complete the lithotripsy in patients in which the Accordion device is used in contrast to when such a device is not employed.

This is an observation, single site-study with one study visit during which all data and samples will be collected. Study participants will be asked to provide blood, urine, and fecal samples so that the investigators may study the differences in the gut microbiota, vitamin K2 levels, and other parameters between participants who form kidney stones and those who do not.

The primary goals of this study are to determine the contribution of dietary oxalate absorption, renal oxalate handling, and endogenous oxalate synthesis to urinary oxalate excretion in normal Body Mass Index (BMI) and obese calcium oxalate kidney stone formers.
