Meta-analysis of the effect of biofeedback electrical stimulation on postpartum stress urinary incontinence in recent 5 years.

Abstract

<h4>Background</h4>To systematically evaluate the therapeutic effect of biofeedback electrical stimulation on postpartum stress urinary incontinence (PSUI) in the past 5 years.<h4>Method</h4>We searched CNKI, WF, VIP, CBM, Cochrane Library, Web of Randomized controlled trials of biofeedback electrical stimulation for PSUI in Science, Embase, and PubMed databases were searched from July 2019 to July 2024. The outcome indexes included clinical efficacy, pelvic floor muscle strength and ICI-Q-SF score. Literature screening and data extraction of included literatures were conducted independently by 2 reviewers, and literature quality was evaluated according to the standards of the Cochrane Collaboration network. Data analysis was performed using Review Manager 5.3 and stata14.0 software.<h4>Results</h4>A total of 15 literatures were included, with a total of 1362 patients, including 681 in the observation group and 681 in the control group. The results of meta-analysis showed the clinical efficacy of patients in the observation group (OR = 4.11, 95% CI = [3.01-5.60], P < .01). Basin muscle strength (OR = 6.01, 95% CI = [3.64-9.94], P < .01); International Consultation on Incontinence Questionnaire - Short Form score (SMD = -2.07, 95% CI = [-2.63 to -1.52], P < .01).<h4>Conclusion</h4>Biofeedback electrical stimulation has certain curative effect on PSUI, and the therapeutic effect is more significant than that of the control group, which can effectively improve the quality of life of patients with PSUI.
