Filter by: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).
This research aims to study the effectiveness of silodosin in the management of lower ureter stones larger than 6 mm in diameter in terms of affected ureter (right or left), the size of the stone, the degree of hydronephrosis, the rate of stone expulsion(day), whether the stone was completely expelled or not, and the side effects of silodosin.
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.
This is a multicenter prospective trial with randomized and observational cohorts assessing patient-reported outcomes and unplanned healthcare utilization following ureteroscopic treatment of renal and ureteral stones, with placement versus omission of a ureteral stent. Eligible participants in the randomization trial will be randomized to ureteroscopy with stent placement or stent omission. Eligible participants that consent to the observational only cohort will complete surveys and the treating physicians will decide the treatment options for the participants. The study team hypothesizes that: - Pain interference change from pre-surgery to Day 7-10 will differ between the two treatment arms. This hypothesis will be evaluated separately in the randomized and observational cohorts. - Unplanned healthcare utilization in the treatment arms will have different unplanned healthcare utilization ranks leading to a win proportion significantly higher or lower than 0.5 in the stent omission arm compared to the stent placement arm. This hypothesis will be evaluated separately in the randomized and observational cohorts.
The aim of this study is to evaluate the clinical efficacy and safety of MET after ESWL in pediatric urolithiasis.
This study is designed to provide an evaluation of currently available disposable flexible ureteroscopes in real-world conditions. Due to high re-processing costs associated with re-usable flexible ureteroscopes, there has been a demand for Urologic device manufacturers to provide single-use flexible ureteroscopes.
The purpose of this study is to assess the accuracy of ultrasound and traditional fluoroscopy to find the residual fragments before retrograde intrarenal surgery is complete. This would ultimately limit the need for radiation exposure and improve the quality of clinical care given to patients and healthcare teams.
The aim of this study is to compare outcomes of endoscopic combined intrarenal surgery (ECIRS) with the multi-tract percutaneous nephrolithotomy for management of complex renal stones.
Epidemiological studies have shown a progressive increase in the incidence of pediatric urolithiasis over the past few decades.
We plan to investigate whether usage of a mobile health platform for surveillance of stone formers by itself or as an adjunct to standard office-appointments will improve patient compliance and adherence to treatment guidelines and ultimately improve patient care, satisfaction, quality of life, and decrease stone recurrence.
