Progression from tubulovillous adenoma to high-grade adenocarcinoma in Indiana pouch urinary diversion
نویسندگان
چکیده
Urologists are aware of the increased risk of adenocarcinoma in urinary diversions that mix urine and feces, such as ureterosigmoidostomy.1 There are also several published case reports of this occurring in isolated bowel segments that are used for urinary reconstructions after cystectomy for several diseases, both benign and malignant. Here, we update a previous case report of an adenoma in an Indiana pouch urinary diversion, with further progression to a high-grade adenocarcinoma over 4 years.2
