Abstract:
We present a rare case of colonic adenocarcinoma occurring in an Indiana pouch. A 68-year-old man underwent radical cystectomy with Indiana pouch urinary diversion for the treatment of bladder cancer 16 years ago. He was referred to our hospital for the treatment of a right staghorn stone, left renal stone, and pouch stones. Cystoscopic findings showed a 10×10 mm tumor distal to ureter anastomosis. Under the diagnosis of colonic adenocarcinoma in an Indiana pouch, tumor and stones were successfully removed. Adenocarcinoma occurrence after ureterosigmoidostomy is well-known. However, diagnosis of adenocarcinoma in an Indiana pouch is extremely rare.
