Efficacy Comparison between Kegel Exercises and Extracorporeal Magnetic Innervation in Treatment of Female Stress Urinary Incontinence: A Randomized Clinical Trial.

Background and Objectives: To estimate the effectiveness of Kegel exercises versus extracorporeal magnetic innervation (EMI) in the treatment of stress urinary incontinence (SUI). Materials and Methods: A parallel group, randomized clinical trial was conducted in the Department of Obstetrics and Gynecology, Clinical Hospital Centre Zagreb, Croatia. After assessing the inclusion/exclusion criteria, each eligible participant was randomized to one of the two observed groups by flipping a coin: the first group underwent treatment with Kegel exercises for 8 weeks, while the second group underwent EMI during the same time interval. The primary outcome was the effectiveness of treatment as measured by the ICIQ-UI-SF overall score, eight weeks after the commencement of treatment. Results: During the study period, 117 consecutive patients with SUI symptoms were assessed for eligibility. A total of 94 women constituted the study population, randomized into two groups: Group Kegel (N = 48) and Group EMI (N = 46). After 8 weeks of follow-up, intravaginal pressure values in the EMI group were 30.45 cmH2O vs. the Kegel group, whose values were 23.50 cmH2O (p = 0.001). After 3 months of follow-up, the difference was still observed between the groups (p = 0.001). After the end of treatment and 3 months of follow-up, the values of the ICIQ-UI SF and ICIQ-LUTSqol questionnaires in the EMI group were lower than in the Kegel group (p < 0.001). Treatment satisfaction was overall better in the EMI group than in the Kegel group (p < 0.001). Conclusions: Patients treated with EMI had a lower number of incontinence episodes, a better quality of life, and higher overall satisfaction with treatment than patients who performed Kegel exercises.
