Brief Summary
Bladder cancer is the 4th most common cancer in men and 5th most common type of cancer in Canada. Urothelial cancer accounts for approximately 90% of malignancies. At diagnosis, over 75% of cases are classified as non-muscle invasive (NMIBC), and with appropriate treatment, the majority of these patients achieve positive outcomes. The progression rate of NMIBC to Muscle-invasive bladder cancer (MIBC) varies between 5-50% at 5 years dependent on histopathological features such as grade, stage, presence of CIS and age (Carcinoma in Situ). The optimal treatment of MIBC (T2-T4N0M0) consists of neoadjuvant cisplatin-based chemotherapy followed by Radical cystectomy and urinary diversion (RCUD). In the last couple of decades, RCUD has also gained attention for treating patients with high-risk non-muscle invasive bladder cancer. Despite advancements in surgical techniques and the rise of minimally invasive alternatives, complications after surgery remain frequent, with morbidity rates of approximately 50%. Several uncertainties persist in surgical practice, including the role of perioperative ureteric stenting during RCUD. Perioperative ureteric stenting is intended to minimize urinary leakage from the newly created uretero-enteric anastomosis and to prevent early obstruction caused by anastomotic swelling. However, stenting may increase the risk of urinary tract infections (UTIs) and necessitate additional follow-up for stent removal. Peng et al. conducted the most recent systematic review in 2021, demonstrating that ureteral stents in RCUD were linked to higher rates of anastomotic strictures. Their review did not provide evidence that these stents were more effective than not using stents in preventing post-diversion urinary leakage. The review underscored the scarcity of prospective randomized controlled trials examining the safety and effectiveness of stenting in this context. The sole prospective (non-randomized) study assessing stent dwell / retention time after RCUD demonstrated early stent removal (2 weeks) had decreased 90-day readmissions and UTIs. Therefore, the investigators aimed to determine the feasibility of conducting a definitive randomized trial to evaluate patients undergoing radical cystectomy and ileal conduit formation to receive either early stent removal (5-7 days) or late stent removal (4-6 weeks).
