To evaluate the clinical efficacy of extracorporeal magnetic stimulation for the treatment of stress and urge urinary incontinence in women.
A total of 35 patients with stress incontinence and 17 with urge incontinence were enrolled in this study. All patients were evaluated by means of a detailed history of incontinence, a gynecologic examination, urine culture, urinary system ultrasound and a urodynamic study. All patients were asked to keep a 3-day voiding diary. A pad-weighing test was done for each patient at their first visit. For treatment, the patients were seated on a special chair containing a magnetic field generator. Pelvic floor muscle stimulation was performed for 20 min (10 min at 5 Hz and 10 min at 50 Hz) twice a week for a total of 8 weeks. The mean follow-up period was 16.8 months (range 12-32 months). A total of 44 patients completed 1 year of follow-up and were re-evaluated by means of voiding diary, pad-weighing test and cystometric study.
Of the 44 patients, 11 (38%) with stress incontinence and 6 (40%) with urge incontinence were cured 1 year after the treatment. In addition, there was an improvement in symptoms in 12 patients (41%) in the stress group and 7 (47%) in the urge group. Pad weight was reduced from 15.4 to 5.8 g in the stress group and from 12.4 to 4.7 g in the urge group (p = 0.000 and 0.001, respectively). Mean Valsalva leak point pressure was increased from 87.3 +/- 15.9 to 118.0 +/- 11.0 cmH (2) O in the stress group (p = 0.000).
Extracorporeal magnetic stimulation therapy offers a non-invasive, effective and painless treatment for stress and urge incontinence in women.
