SURVEILLANCE COLONOSCOPY OF PATIENTS WITH URETEROCOLONIC ANASTOMOSES

Abstract

Rectosigmoidoscopy was performed in 10 patients who had undegone radical cystectomy and bilateral ureterosigmoidostomy more than five years before. All cases were males with their mean age at operation 58.7 years and their mean duration of ureterosigmoidostomy 8.8 years. 13 ureteral orifices in the 10 patients were found at a mean distance of 17.6cm from the anal dentate line. The appearances of the ureteral orifices were classified into two. 10 sites in 9 patients had polypoid appearance and 3 sites in 2 patients had flat appearance. 1 patient out of the 10 (10%) had adenocarcinoma just above the dentate line and an adenomatous polyp between bilateral ureteral orifices. Biopsies of macroscopically normal mucosa around the ureterocolonic anastomoses performed for all cases proved to be histologically mild inflammation. In 3 cases, biopsies of the polypoid ureterocolonic anastomoses showed granulation tissue and mild inflammation.
