Filter by:The goal of this observational study is to investigate the alterations in gut microbiota and metabolites among patients with uric acid stones following the administration of potassium sodium hydrogen citrate. The main question it aims to predict the potential metabolic mechanism and therapeutic target of potassium sodium hydrogen citrate in treating uric acid stones through analysis of gut microbiota and metabolomics. The participants were required to undergo a 3-month drug intervention, providing blood, urine, and stool samples before and after treatment. No additional interventions were implemented for the subjects.
The aim of this study is to test the efficacy of the two long-acting thiazide-like diuretics indapamide and chlorthalidone in reducing urine supersaturation for calcium oxalate and calcium phosphate compared to the short-acting thiazide diuretic hydrochlorothiazide for the prevention of calcium-containing kidney stones.
Primary aim: comparing the efficacy of standard PCNL and endoscopic combined intrarenal surgery (ECIRS) in the Galdakao-modified Supine Valdivia (GMSV) position in a single session for the treatment of complex nephrolithiasis in obese patients. Secondary aim: comparing safety and complications of standard PCNL and ECIRS in the GMSV.
This is a prospective randomized controlled trial designed to assess the efficacy and safety of Lumenis® Pulse™ P120H holmium laser system with the Moses technology (holmium laser with pulse modulation) versus the Soltive™ SuperPulsed Laser System with the thulium fiber laser (thulium fiber laser), in dusting of renal stones during ureteroscopy with laser lithotripsy. 310 participants will be enrolled across 5 research sites.
The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: - Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. - Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. - Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.
In this study, investigators aimed to compare the postoperative pain status and comfort situations depending on instruments used in the percutaneous nephrolithotomy operation
The goal of this [ type of study:]prospective randomized clinical trial. The main question is to compare the outcomes of mini-percutaneous nephrolithotomy (m-PCNL) and retrograde intrarenal surgery (RIRS) in treating upper urinary tract calculus in children ≤ 10 years.
The purpose of this study is to compare two variations of the mini-PCNL procedure using either a vacuum-assisted sheath or standard sheath which are both used for the surgical treatment of kidney stones. Both procedure types are commonly used in the treatment of kidneys stones and they have been shown to be safe and effective in the treatment of stones similar in size and location to your own.
Evaluation of Prevalence, Molecular and Genetic Backgrounds of Calcium-Based stones among Patients with Renal Calcular Disease in Mansoura Urology and Nephrology Center
Nephrolithiasis is the most common chronic kidney condition and affecting approximately one in every 10-17 people in the world[1,2]. Flexible ureteroscopy (f-URS) has become one of the most common treatments for ureteral and renal stones with minimal complications. The development of ureteral access sheath (UAS) is a significant advance in flexible ureteroscopic management of urinary stones. The UAS has two major advantages: 1) facilitating multiple entries into the renal collecting system without causing recurrent trauma to the ureter and permit expeditious basketing of multiple stone fragments, 2) improving the irrigation with better fluid outflow, thereby reducing the renal pelvic pressure (RPP) and risk of infectious complications. The tip bendable suction ureteral access sheath (S-UAS) is a novel UAS that has good flexibility and deformability at the tip, which can passively bend (bend >90°) with the bending of f-URS and can connect to a vacuum suction device. Preliminary study showed that S-UAS can follow f-URS to cross the UPJ and into the renal pelvis and calices. S-UAS close to the stone can achieve complete stone-free status in RIRS. However, further clinical studies and comparisons with available techniques are required. This prospective, single-blinded, single-center, randomized control trial will evaluate the stone free rates, operative time, postoperative complications following RIRS with S-UAS. To the best of our knowledge, this is the first study to compare the clinical benefits of RIRS with S-UAS and traditional UAS.
