title: Internal urinary sphincter in maintenance of female continence.
abstract: The integrity of the bladder neck was assessed in 98 continent women. Radiological and physiological evidence showed that half of these women had an incompetent bladder neck, but they were still continent. These data devalue the urodynamic finding of an incompetent bladder neck as an indication for surgery for incontinence and question the physiological importance of the internal sphincter.
