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. Retrospective analysis of TPE patients with incontinent urinary diversions between August 2013 and January 2020. 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. 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.
