In such cases, reabsorption of urinar...

Carcinoma of sigmoid colon following urinary diversion: a case report and review of literature

BACKGROUND The association of ureterosigmoidostomy with colonic cancer is well established. A 100-fold increased risk of malignancy has been proposed in association with ureterosigmoidostomy. Characteristically there is a latent period of around 20-30 years before the occurrence of cancer. CASE PRESENTATION An unusual case of adenocarcinoma of the colon in a 36-year-old patient is presented. ...
