title: Ureterosigmoidostomy followed by carcinoma of the colon.
abstract: Adenocarcinoma of the colon developing as a late complication or ureterosignoidostomy has been reported with increasing frequency. A patient is presented who developed adenocarcinoma of the colon 28 years after ureterosigmoidostomy for bladder exstrophy and 13 years after conversion of the ureterosigmoidostomy to an ileal conduit. The colonic tumor was documented at postmortem examination to be at the ureterosigmoidostomy site. Because of the potential late development of adenocarcinoma of the colon, careful follow-up of patients with ureterosigmoidostomies, particularly those performed in children many years ago, is indicated.
