Effectiveness of electroacupuncture for female stress urinary incontinence: a systematic review and Meta-analysis.

To evaluate the effectiveness of electroacupuncture (EA) for female stress urinary incontinence (SUI).

We searched 12 databases electronically from inception to November 2018 without language restrictions. We included randomized controlled trials (RCTs) involving women with SUI, but excludd other types of urinary incontinence or studies that were not RCTs. Two independent reviewers extracted study characteristics, with disagreements resolved by consensus. Data were pooled and expressed as mean difference (MD) for continuous outcomes and relative risk (RR) for dichotomous outcomes, with 95% confidence intervals (CI). This study was registered with the International Prospective Register of Systematic Reviews (number CRD42018089734).

We found very low to high level evidence that EA improved the effective rate (RR = 2.03, 95%CI: 1.40, 2.95; P = 0.0002) and reduced urine leakage as measured by the 1-hour pad test (MD = 3.33, 95%CI: 0.89, 5.77; P = 0.008), International Consultation on Incontinence Questionnaire Short Form score (MD = 3.14, 95%CI: 2.42, 3.85; P < 0.00001), and 72-hour incontinence episodes (MD = 1.17, 95%CI: 0.56, 1.78; P = 0.0002) compared with sham electroacupuncture (SA), pelvic floor muscle training, and medication.

The effectiveness and safety of EA for key outcomes for women with SUI are statistically significantly better than those of SA, but most available evidence is very low or low quality. More well-designed RCTs are needed to confirm these findings.
