Abstract:  We present a case of a tubulovillous adenoma in an Indiana pouch managed by endoscopic resection. A 66-year-old male underwent a cystectomy with creation of an Indiana pouch urinary diversion for invasive small cell carcinoma of the bladder. Seven years following his initial surgery, the patient noted several episodes of gross hematuria. The evaluation revealed a 2.5 cm tubulovillous adenoma with high-grade dysplasia within the Indiana pouch. The patient had significant comorbidities precluding an open operative procedure. He underwent en endoscopic resection of the tumor, and subsequently has been managed with surveillance pouchoscopy, biopsies, and fulguration every 3 months.
