Randomized, Placebo Controlled Study of Electrical Stimulation With Pelvic Floor Muscle Training for Severe Urinary Incontinence After Radical Prostatectomy

Purpose: We evaluated electrical stimulation combined with pelvic floor muscle training for urinary incontinence after radical prostatectomy in a randomized controlled study.Materials and Methods: A total of 56 men with severe urinary incontinence (more than 200 gm daily), mean ± SD age 66.6 ± 6.2 years, were randomized to an active treatment group (26) or a sham group (30). All patients performed pelvic floor muscle training preoperatively and continued throughout the study. For active stimulation 50 Hz square waves of 300 μs pulse duration and a 5 seconds on, 5 seconds off duty cycle were applied for 15 minutes twice daily with an anal electrode. Sham stimulation was limited to 3 mA with a 2 seconds on, 13 seconds off duty cycle.Results: In the active group 8 (36%), 14 (63%), 18 (81%) and 19 (86%) patients were continent (22) vs 1 (4%), 4 (16%), 11 (44%) and 17 (86%) in the sham group (25) (leakage less than 8 gm daily) after 1, 3, 6 and 12 months, respectively. There was a significant difference in the...
