[Results of electrical sensitivity tests of the urethra and vagina in functional urinary incontinence].

Urethral and vaginal sensibility has been tested in 90 patients with urinary incontinence by means of urethral catheter and vaginal electrodes. Monophasic rectangular impulses with a frequency of 2 Hz, a duration of 2 msec and a variable intensity were used. The urethral sensibility threshold was 10.5 mA in patients with urge incontinence and 14.8 mA with stress incontinence. The vaginal sensibility threshold was by 20 mA higher and correlated well with the urethral one in its differentation of stress and urge incontinence. Because the big scattering of the values there was no statistical significance. Therefore this method is only valid to clarify patients complaints and to define impulse parameters for therapeutic intravaginal electric stimulation.
