Assessing the impact of ureteral rest duration before surgery for ureteral stricture
Official title: Study to Assess Duration of Ureteral Rest Prior to Ureteral Reconstruction Surgery
Run by Northwestern University · NCT06384079 · Data updated 2026-11-12
This study is trying to see if the length of time a ureter is rested before surgery can affect how long the ureteral strictures are in adults who are about to have surgery for this condition.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults over 18 years old who are undergoing ureteral reconstruction surgery for ureteral stricture.
✕Probably not a fit
Patients under 18 years of age or those unable to provide informed consent may not benefit from this study.

What this trial studies
This observational study aims to evaluate how the duration of ureteral rest, defined as the time from switching from a ureteral stent to a percutaneous nephrostomy, affects the length of ureteral strictures prior to undergoing ureteral reconstruction surgery. Participants will be adults who are scheduled for this type of surgery and have consented to the study. The study will involve the use of antegrade and retrograde pyelograms to gather relevant data on stricture length. The findings could provide insights into optimal pre-surgical management for patients with ureteral strictures.
Why it matters
Potential benefit: If successful, this study could help optimize pre-surgical management and improve surgical outcomes for patients with ureteral strictures.
How similar studies have gone: While this approach is observational and may not have been extensively tested, similar studies have shown the importance of pre-surgical management in improving outcomes.
