This study deals with the diagnosis of fecal incontinence established by electromanometric measurements of the anal closure. Two cases are reported, and our data examined in a control group of the same age will be presented. To evaluate the pressures in the rectum and anal canal we used instruments of the urodynamic unit with water-perfused catheters. The results demonstrate that the resting anal canal pressure is lower in incontinent than in continent women. The anal closure pressure during coughing and squeezing becomes negative in incontinent women. These findings are in accordance with the data reported by others.
