Abstract

An increased risk of neoplasm has been noted when bowel segments are used for urinary diversion. Particularly true for ureterosigmoidostomy, colonic adenocarcinoma has rarely been reported following Indiana Pouch diversion. This report describes a 42-year-old woman with a history of bladder exstrophy who developed a polyp in her Indiana Pouch 24 years after its creation. The polyp, found incidentally, was a tubular adenoma with high-grade dysplasia. Due to its malignant potential, the polyp was resected with preservation of the Indiana Pouch. This case highlights the need for lifetime surveillance in urinary reservoir patients who received diversions at a young age.
