A transrectal ultrasound technique is described for imaging the bladder neck and urethra. A group of 25 continent female volunteers was examined initially; 59 incontinent women were then studied pre-operatively and again 6 months after either a Burch colposuspension, Pereyra operation or ox fascial sling to determine the ultrasonic characteristics of successful surgery.
