膀胱全摘除術，Indiana pouch造設術後8年目に発生した両側尿管腫瘍の1例

Abstract

A 46-year-old man underwent total cystectomy and Indiana pouch urinary diversion for bladder cancer in 2001. Pathological examination revealed an urothelial carcinoma of the bladder (pT2N0M0). He was referred to our hospital for bilateral hydronephrosis in June 2009. Cytological examination of the urine was negative. Percutaneous nephrostomy was performed, and we suspected bilateral ureteral tumors from pyelo-ureterography. Percutaneous ureteroscopy revealed a papillary tumor in the right ureter. Since there appeared to be a papillary tumor in the left ureter, we decided to perform ureterectomy for bilateral ureteral tumors, and to keep the bilateral nephrostomy tube for urinary diversion. Pathological examination revealed urothelial carcinoma in bilateral ureters. There has been no sign of recurrence at 17 months after the operation.
