[Effects of biofeedback and pelvic electric stimulation in treatment of stress urinary incontinence].

OBJECTIVE
To investigate procedures and benefits of using bio-feedback and pelvic electric stimulation in treatment of stress urinary incontinence.


METHODS
Forty-six patients with stress urinary incontinence were included randomly into the study and treated with Stimogyn BIO 2001 treatment equipment. Treatment procedures and benefits were observed.


RESULTS
Among 46 patients, 43 cases achieved improvement with an effective rate of 93%. Nineteen patients in premenopause received 4-30 times treatments with an average of 9.8. Effectiveness time was 1-10 with an average time of 3.6. Twenty-seven patients in postmenopausal period received same treatments with an average of 10. Effectiveness time was 1-10 with an average time of 4.2. Average treating time was 40 minutes. Forty patients had follow-up information, but 6 patients were lost to follow-up. Nine patients were cured, including 3 patients with stress incontinence after hysterectomy. Four patients chose surgical treatment after successful conservative treatment. Three patients recurred. Patients who experienced recurrence were cured or improved after receiving conservative therapy again. Body mass index (BMI) and severity of stress incontinence might have different influences on treating times, but had no influence on the outcomes of treatment (P > 0.05).


CONCLUSIONS
Biofeedback and pelvic electric stimulation could be used to treat stress incontinence. Menopause status, BMI and severity of stress incontinence can not obvious affect the outcomes of biofeedback and pelvic electric stimulation.
