We treated 20 men with persistent post-prostatectomy incontinence by biofeedback-assisted behavioral training procedures. Initially, scheduled 2-hour voiding resulted in a mean 33.1 per cent increase in urge incontinence, a mean 28.5 per cent decrease in stress incontinence and no change in continual leakage. Subsequently, biofeedback was used to teach selective control of the sphincter muscles and/or inhibition of detrusor contractions. Individualized home practice included a voiding schedule, sphincter exercises, active use of the sphincter to prevent urine loss and strategies to manage urgency. After 1 to 5 biofeedback sessions patients with urge incontinence demonstrated an average 80.7 per cent decrease in incontinence, while stress incontinence was decreased an average 78.3 per cent and patients with continual leakage were less successful, with a mean 17.0 per cent improvement. The findings indicate that biofeedback training is an effective intervention for episodic stress or urge incontinence after prostatectomy. However, its usefulness appears to be limited in patients with postoperative incontinence characterized by continual leakage.
