Unusual fistulae between the rectum and the lower urinary tract: simple techniques for diagnosis.
This paper presents two unusual fistulae between the rectum and the lower urinary tract in adults, one a posttraumatic fistula following dilatation of a sigmoid colon stricture and the other a congenital anomaly. In both cases a contrast enema was negative; in one case a voiding cystourethrogram was negative. The fistula was demonstrated in case 1 by repeating the enema and having the patient raise his intraabdominal pressure, and in case 2 by having the patient hold while attempting to pass flatus during a cystogram, which demonstrated gas bubbles entering the bladder.
