Evaluation of female urinary incontinence device.

A new silicone rubber inflatable vaginal pessary has been evaluated in 33 patients with stress incontinence due to urethral sphincter dysfunction (genuine stress incontinence), confirmed by urodynamic assessment. Nine of 20 patients who used the device for one month showed subjective improvement and 2 patients have continued to use the device. Urodynamic changes include a marked increase in maximum urethral closure pressure and elevation of the bladder neck.
