Study to Evaluate How Time Without a Ureteral Stent Affects Ureteral Stricture Before Reconstruction Surgery

What this Trial Is About

Researchers are studying how the length of ureteral restthe time between changing a ureteral stent to a percutaneous nephrostomy tubeaffects the length of ureteral strictures before surgery to repair the ureter. The study focuses on patients with ureteral strictures who are preparing for ureteral reconstruction surgery. The goal is to better understand this timing to potentially improve surgical outcomes. Participants will undergo antegrade and retrograde pyelogram procedures before their ureteral repair surgery. These imaging tests are used to measure the ureteral stricture length and quality at two time points 2 weeks and 6 weeks after the procedure. The study is observational, and all participants will receive these imaging evaluations as part of the research. During the study, participants will be monitored through these imaging assessments to evaluate the stricture length and whether the narrowed segment is classified as narrowed or obliterated. The study will review these measurements to assess the effect of ureteral rest duration. Participation involves signing informed consent and completing the imaging procedures, with no additional treatments or interventions required. The study is expected to continue until November 2030.
