Introduction: Total pelvic exenteration (TPE) for rectal cancers is associated with significant morbidity. We evaluated the complications related to urinary reconstruction following TPE and factors predicting urologic morbidity. Methods: Retrospective analysis of TPE patients with incontinent urinary diversions between August 2013 and January 2020. Results: One hundred TPE were performed with 96 ileal conduits (IC). Early complications occurred in 10 patients that included uretero-ileal leaks (5%), conduit-related complications (3%), and acute pyelonephritis (3%). Late complications were seen in 26% of patients with uretero-intestinal strictures in 11%. Mortality attributable to urinary complications was seen in 2%. No single factor, including prior radiation, recurrent disease, type of anastomosis, or blood loss, predicted development of urinary morbidity. Conclusion: Conduit urinary diversion following TPE is associated with high urinary morbidity rate but low mortality. It can be safely performed even after previous surgeries and radiation by a dedicated colorectal team.
