Abstract: Objective：To assess the clinical effectiveness of the conservative treatment of female stress urinary incontinence （SUI） with the pelvic floor muscle training（PFMT） combined with biofeedback and electrical stimulation（ES）, and the application of the surface electromyography on the pelvic floor muscles in clinical practice. Methods：79 patients with SUI were treated with the PFMT combined with biofeedback and ES. The surface electromyography and clinical symptoms were observed after treatment. Results：There were significant improvement in the surface electromyography after treatment（P＜0.01），while the changed levels after treatment in the mild incontinence group and in the moderate incontinence group were coincident（P＞0.05）. Total effective rate was 81.0% after 3 months follow-up, while the effective rates the mild incontinence group and the moderate incontinence group were similar（P＞0.05）. Conclusions：PFMT combined with biofeedback and EI is noninvasive and effective in treatment of female SUI, and the surface electromyography was a useful test to assess the curative effect.
