NCT ID: NCT06394908 Enrolling by invitation - Urolithiasis Clinical Trials

Registry of MIUS for Urolithiasis (ReMIUS-U)

ReMIUS-U
Start date: May 10, 2023
Phase:
Study type: Observational [Patient Registry]

The purpose of this registry is to collect data on patients who have undergone minimally invasive treatments for urinary system stone disease, including percutaneous nephrolithotomy (PCNL), shock wave lithotripsy (SWL), semi-rigid ureterorenoscopy (URS), and flexible ureterorenoscopy (F-URS).

NCT ID: NCT04746378 Enrolling by invitation - Urolithiasis Clinical Trials

PRedictive Accuracy of Initial Stone Burden Evaluation.

PRAISE
Start date: September 9, 2021
Phase:
Study type: Observational

This study is intended to be a prospective registry of patients undergoing any kind of stone treatment that have a pre-operative CT available. This imaging will be used to measure the stone burden in three different ways: in a single dimension (cumulative stone diameter), in two dimensions (surface area) and in three dimensions (volume).The primary purpose is to identify what way of measuring stone burden is most predictive of outcomes after stone treatment such as stone free status, operative time and complications.

NCT ID: NCT04398251 Enrolling by invitation - Urolithiasis Clinical Trials

A Randomized Clinical Trail of The Effect of Postoperative Uric Acid Control on Stone Recurrence and Renal Function in Patients With Hyperuricemia of Urolithiasis.

Start date: April 10, 2020
Phase: Phase 4
Study type: Interventional

The purpose of this study was to explore the effects of uric acid control on stone recurrence and renal function in patients with calculi of hyperuricemia through a prospective controlled study.

NCT ID: NCT01127854 Enrolling by invitation - Urolithiasis Clinical Trials

Pilot Study to Evaluate the Contribution of Gene Variants to Idiopathic Urolithiasis

Start date: December 2009
Phase:
Study type: Observational

Recent investigations from this group have identified that genetic variants of genes associated with monogenic forms of nephrolithiasis are expressed in idiopathic calcium oxalate kidney stone patients and could influence stone forming risk. Utilizing patient samples from the Mayo Clinic Florida Kidney Stone Registry, we will demonstrate that expression of these heterozygous mutations in idiopathic nephrolithiasis act as genetic modifiers of disease presentation increasing risk of kidney stone formation. Complimented by the analysis of environmental and lifestyle risk factors, these studies will define environmental and genetic susceptibility factors involved in kidney stone formation and reoccurrence.
