Long-term results of a clinical trial comparing isolated vaginal stimulation with combined treatment for women with stress incontinence
To determine the efficacy of stress urinary incontinence treatments adding pelvic floor muscle training to vaginal electrical stimulation.
Forty-eight women with stress urinary incontinence were randomized into 2 groups: 24 underwent isolated vaginal electrical stimulation, and 24 vaginal electrical stimulation plus pelvic floor muscle training. History, physical examination, voiding diary, perineum strength test, and urodynamic study were assessed. Comparisons were made for adherence to treatment, muscle strength improvement, urinary symptoms, and degree of satisfaction immediately, 12 and 96 months after treatment.
Patients’ degree of satisfaction on vaginal electrical stimulation, and on vaginal electrical stimulation plus pelvic floor muscle training immediately, 12 and 96 months post treatment, were, respectively: 88.2%versus 88.9% 64.7% versus 61.1% and 42.9% versus 28.6% (p>0.05).Conclusion Vaginal electrical stimulation associated to pelvic floor muscle training did not show better results than vaginal electrical stimulation alone.
