T. Weinstein et al., ADENOCARCINOMA AT URETEROSIGMOIDOSTOMY JUNCTION IN A RENAL-TRANSPLANTRECIPIENT 15 YEARS AFTER CONVERSION TO ILEAL CONDUIT, Clinical nephrology, 44(2), 1995, pp. 125-127
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.
