  • Title: [Polyps of the sigmoid and rectum following ureterosigmoidostomy].
    Author: Köpp W, Dienes HP, Schmidt R.
    Journal: Z Gastroenterol; 1980 Mar; 18(3):148-54. PubMed ID: 6999760.
    Abstract:
    Implantation of the ureters in the sigma is practicable as far as cystectomy or congential malformations are concerned. The problem of the development of sigma-rectum polyps following ureterosigmoidostomy (uss) is being discussed within the description of three own case reports. The polyp of our first case is classified as an adenomatous polyp with marked retention of mucus. The polyp of our second case is regarded as a polypoid hamartia caused by the operation. The polypoid lesion of our third case must be regarded as a heterotopia of the urinary tract in connection with the known malformation of the urogenital tract of this patient. Patients who had undergone uss have an increased risk for the development of rectal carcinoma. But on the other hand the polypoid lesions following use must not necessarily be predecessors of carcinomas! In rather seems that the polyps following uss are very heterogenous. Only the first case being described in the present report may be regarded as a potential predecessor of a carcinoma. A tabulated review of the literature of the described polyps after uss is given. Etiological aspects are being discussed.
