STENT X: a Randomized Trial to Assess Stent-free Radical Cystectomy

Overview

Radical Cystectomy (RC) remains the gold standard for localized muscle-invasive bladder cancer (MIBC); however, use of ureteral stents at time of surgery remains controversial without level 1 evidence to comment on risks or benefits of their use. RC complications commonly include urinary tract infections (UTIs), pyelonephritis, ureteroileal leakage and stenosis, and can occur with either ileal conduit or orthotopic neobladder diversions. Traditionally, ureteral stents are thought to support anastomotic healing and reduce the risk of anastomotic leakage and strictures; however, emerging evidence from retrospective studies suggests that stent use may paradoxically increase rates of postoperative morbidity. This randomized, multicenter and prospective study aims to compare 30-day postoperative complication rates between stented and non-stented urinary diversions in patients undergoing RC for MIBC, in both ileal conduit or neobladder with either robotic or open approaches.

Randomization between ureteroenteric anastomosis with or without ureteral stent placement will occur at time of surgery; the surgeon will know this information at time of surgery and the patient will be aware of the placement of stents following surgery as these are externalized and visible. The primary outcome will be complication rate in 30 days after the surgery. Secondary outcomes of this trial will include: length of stay, procedure duration, emergency room visits, patient reported pain, anastomotic leakage rate, ureteral stricture rate, post-operative nephrostomy tube placement, differences in complication rates between interrupted and running suture technique. The study will be conducted across three academic institutions: Brigham and Women's Hospital (BWH), Massachusetts General Hospital (MGH) and Instituto do Câncer do Estado de São Paulo (ICESP), Brazil.
