Biofeedback for the treatment of stress and urge incontinence.
Biofeedback and pelvic floor electrical stimulation are new modalities that have been advocated for the treatment of urinary incontinence. To evaluate the long-term effectiveness of biofeedback and identify factors predictive of a positive outcome, we prospectively studied 28 patients with stress and urge incontinence. All patients were evaluated with a complete history, physical examination, urinalysis and culture. Of 28 patients 21 were also studied with video urodynamics. Biofeedback was performed with the InCare PRS 8900* machine with each patient undergoing at least 6 office sessions. Quantifiable symptoms, such as frequency, nocturia and urgency, were evaluated before and periodically after treatment. Patients also graded the overall treatment response on a scale of 0 to 3. Biofeedback successfully treated 5 of 14 patients (36%) with stress incontinence and 9 of 21 (43%) with urgency incontinence. Treatment response was durable throughout followup in all responding patients. Additionally, there was a statistically significant decrease in daytime frequency and nocturia following biofeedback (p = 0.038 and p = 0.044, respectively). No pretreatment factors predictive of a positive outcome could be identified. Improvement in perineal muscle tone with time approached statistical significance. We conclude that biofeedback is a moderately effective treatment for stress and urge incontinence, and should be offered to patients as a treatment option. Few patients, however, choose biofeedback as a primary mode of therapy and, due to the availability of other highly successful treatments for stress urinary incontinence, it is unlikely to become a popular treatment option.
