Management of advanced adenocarcinoma in Indiana Pouch urinary diversion.

Adenocarcinoma is a rare finding following urinary diversion with gastrointestinal segments. This report describes an 80-year-old woman with a history of bladder cancer who subsequently developed a pT4 adenocarcinoma 8 years following her radical cystectomy and Indiana Pouch continent urinary diversion. An en bloc resection of the pouch and affected small bowel was performed and the patient underwent conversion to an ileal conduit diversion. We use this case to highlight a mechanism for possible pathogenesis and the management of adenocarcinoma in urinary diversions including the need for regular surveillance and the surgical approach.
