title: Surveillance colonoscopy after ureterosigmoidostomy.
abstract: Fourteen patients had surveillance colonoscopy 2 to 48 years after ureterosigmoidostomy urinary diversion. Five patients (37 per cent) had benign polyps distal to the implant sites that were removed but no colon carcinomas were found. We discuss the rationale for surveillance colonoscopy at regular intervals. This procedure may allow greater usage of ureterosigmoidostomy as a means of urinary diversion.
