A 37-year-old woman who underwent a bilateral ureterosigmoidostomy (USS) as a child for bladder exstrophy was scheduled for a surveillance sigmoidoscopy. At 17 cm from the anal verge, a sharply delineated hyperemic mucosal segment with small dilated vessels was seen ([Fig. 1]). Within this segment, an orifice was present where the ureter had been implanted during previous surgery; a pulsatile outflow of clear urine was visible ([Video 1]). Targeted biopsies revealed colonic type mucosa with mild fibrosis and an inflammatory infiltrate, but no dysplasia.

Quality:

USS has long been the most common form of urinary diversion. Colorectal cancer (CRC) risk has been reported to be increased following USS, with a reported incidence as high as 2 % – 15 %. The average latency period is 20 – 26 years [1]. Cancer usually develops at close proximity to the anastomosis, possibly related to carcinogenic nitrosamine compounds produced by the interaction between urine and native colon flora [2]. Adenomatous changes precede carcinoma development, thus enabling surveillance. Tumors usually display similar immunohistochemical markers as sporadic CRC, but more often show poor differentiation and thus aggressive behavior [3]. Periodic surveillance sigmoidoscopy with random and targeted biopsies is advised to detect early neoplastic changes [4].
