Effect of Electroacupuncture Added to Pelvic Floor Muscle Training in Women with Stress Urinary Incontinence: A Randomized Clinical Trial
European Urology Focus(2023)
摘要
Background: Pelvic floor muscle training (PFMT) is a first-line conservative therapy for stress urinary incontinence (SUI). Electroacupuncture (EA) has been used to treat SUI recently. Objective: To compare the effectiveness of PFMT + EA versus PFMT + sham EA for SUI in women.Design, setting, and participants: A prospective, multicenter, randomized, controlled clinical trial was conducted at four hospitals in China involving 304 women with SUI from May 20, 2014 to November 21, 2017. Data were analyzed from April 20 to December 21, 2018.Intervention: Participants were randomized to receive 8 wk of PFMT+ EA (n = 154) or PFMT + sham EA (n = 150).Outcome measurements and statistical analysis: The primary outcome was the change in the amount of urine leakage measured on a 1-hr pad test. Student's t test, the v2 test, and the Wilcoxon rank-sum test were used for data analysis.Results and limitations: Among the 304 participants randomized, 286 completed the study. The mean age was 57.6 yr (standard deviation [SD] 8.9) for the PFMT + sham EA group and 57.2 yr (SD 9.1) for the PFMT + EA group. The mean urine leakage at base-line was 13.6 g for the PFMT + sham EA group and 13.9 g for the PFMT + EA group. After the 8-wk intervention, the PFMT + EA group had a greater decrease in mean urine leak-age (-9.8 g) than the PFMT + sham EA group (-5.8 g) with a mean difference of 4.0 g (95% confidence interval [CI] 0.8-7.2). Significantly more patients experienced a >= 50% reduction in urine leakage and the mean number of incontinence episodes in 24 h in the PFMT + EA group than in the PFMT + sham EA group (26.3%, 95%CI 15.8-36.8%). The PFMT + EA group experienced better improvement in participant-reported SUI severity at 6 wk (p < 0.001) and 8 wk (p < 0.001) and self-evaluated therapeutic effects at 2- 32 wk (p < 0.001) after the intervention. Lack of measurement of the amount of urine leakage during follow-up is a limitation.Conclusions: In this randomized clinical trial, 8-wk combined treatment with PFMT + EA led to a greater improvement in SUI symptoms and better outcomes than with PFMT + sham EA.Patient summary: We evaluated the effectiveness and safety of pelvic floor muscle train-ing combined with electroacupuncture for stress urinary incontinence in women, Our results show that this is a promising therapeutic approach for the treatment of stress uri-nary incontinence.(c) 2022 The Authors.
