ADENOCARCINOMA AT URETEROSIGMOIDOSTOMY JUNCTION IN A RENAL-TRANSPLANTRECIPIENT 15 YEARS AFTER CONVERSION TO ILEAL CONDUIT

In recent years, adenocarcinoma of the colon mucosa has become a recog nized complication of ureterosigmoidostomy and in most cases the tumor arises at the site of ureterocolonic anastomosis. We report a case of a 29-year-old renal transplant recipient who developed two colonic ca rcinomas at the site of ureterosigmoidostomy 25 years after the urinar y diversion and 15 years after conversion to an ileal conduit. This ca se emphasizes the need for a careful life-long follow-up of all patien ts who undergo ureterosigmoidostomy.
