title: Benign colonic neoplasm at the site of ureterosigmoidostomy.
abstract: A benign colonic polyp with epithelial dysplasia developed in a young male at the site of ureteral implantation in the sigmoid colon following ureterosigmoidostomy for urinary incontinence. Patients with ureterosigmoidostomy represent a high-risk cancer group, and a review of the literature suggests the necessity of a life-long follow-up in these patients. A follow-up plan with Hemoccult test each year and a sigmoidoscopy every 3rd year is proposed.
