In order to evaluate urethral sphincteric function, urethral pressure profile (UPP) was studied by the method of Brown-Wickham with modifications in 18 patients with stress incontinence, and 22 normal females were used as control. Concomitantly, cystourethrography combined with the insertion of a watch chain into the urethra was studied in 13 patients with stress incontinence. The results obtained are as follows : 1. The greatest urethral pressure (UPmax) was found in the middle portion of the urethra. 2. In the control group, the mean value of UPmax was 86.1 cm H_20 with standard deviation of ±I 5.9. In general, UPmax showed a tendency to decrease with increasing age. The physiological urethral length determined with UPP was 3.6 ± 0.4 cm. 3. In the stress incontinence patients, UPmax was 46.7 ± 9.5 cm H_2O, being significantly lower than that of the controls. The physiological urethral length was 3.1 ± 0.5 cm and it was significantly shorter than that of the controls. 4. Posterior urethrovesical angle on cystourethrogtaphy exceeded 120゜ in the stress incontinence patients. 5. It is of considerable practical significance that bladder pressure rose above UPmax by abdominal pressure during a deep cough in most patients with. stress incontinence. These findings indicate that the UPP examination is of actual value in diagnosis for stress incontinence.
