[Discussion of a spontaneous uretero-colonic fistula with stone formation in the rectum (author's transl)].

The unusual course of a vesico vagino-rectal fistula with spontaneous development of a uretero-colonic fistula in a patient with carcinoma of the cervix is presented. After a double-barrel colostomy had been performed kidney function remained normal for many years. Because of incontinence of the anal sphincter the urinary drainage has been undisturbed inspite of stone formation in the rectum.
