[Ureteral lesions after abdomino-perineal resection of the rectum].

Three ureter lesions in abdominoperineal rectum amputations are described. The surgical literature on this subject is discussed. Particularly dangerous points in the procedure of abdominoperineal rectum amputation concerning injuries of the ureter are accentuated. Possibilities of avoiding and recognizing early ureter injuries are indicated. More attention should be given to intraoperative lesions of the ureter.
