Abstract
This study sought to determine the characteristics of women in whom pelvic floor electrical stimulation will reduce stress urinary incontinence. It also evaluates how long electrical stimulation should be used before significant improvements are seen in clinical outcomes. Subjects with genuine stress incontinence were enrolled into a multicenter non-randomized trial. They used electrical stimulation for 15 minutes twice daily or every other day for 20 weeks. At the end of 20 weeks, those with a 50% reduction in leakage episodes on voiding diary (‘responders’) were compared with those who did not show a 50% reduction (‘non-responders’). Thirty-one subjects were enrolled and 28 completed the study. After the treatment period, 19 subjects were defined as responders and 9 as non-responders. There were no significant differences between the two groups in baseline demographics (e.g. age, parity, largest birth weight etc.) other than body mass index (greater in nonresponders). Significant subjective and objective improvements were noted among responders by 10 and 14 weeks, respectively. Compliance was higher in responders during weeks 12–15 of the study (P=0.05). It was concluded that a minimum of 14 weeks of pelvic floor stimulation was necessary before significant objective improvements were seen. Body mass index and patient compliance may affect success.
