An adenomatous polyp developed at the site of ureteral implantation in the sigmoid colon in a patient, 38 years after bilateral ureterosigmoidostomy. A review of the case reports in the literature infers an etiological relationship between ureterosigmoidostomy and the development of colonic neoplasm. The technical advantages of ureterosigmoidostomy and its recent modifications over the presently popular ileal conduit indicate that ureterosigmoidostomy may be returning to a place of prominence in the treatment of neoplasm of the bladder. A plea is made for frequent proctosigmoidoscopic and radiographic examinations of those patients who would present the possibility of subsequent colon lesions.
