This study examined the effectiveness of various electrical stimulation methods in alleviating symptoms and enhancing the quality of life for women with urinary incontinence. We conducted a systematic search of PubMed, Cochrane Library, PEDro, EMBASE, and ClinicalTrials.gov from inception to August 2024. Randomized controlled trials (RCTs) that meet following criteria were included, urinary continence in women, using various electric stimulation treatments and evaluated outcomes related to symptoms, quality of life. Thirty RCTs were subjected to risk of bias assessment, certainty of evidence, and network meta-analysis. Statistical analysis was performed using a random-effects model, with continuous variables expressed as standardized mean difference (SMD) and 95% confidence interval (CI). Percutaneous tibial stimulation (SMD - 1.86, 95% CI - 2.77 to - 0.96) and intravaginal stimulation (SMD - 0.97, 95% CI - 1.55 to - 0.38) significantly reduced symptom severity. Additionally, percutaneous tibial, intravaginal, transcutaneous tibial, and trans-sacral stimulations improved quality of life. Percutaneous tibial stimulation was the most effective, followed by intravaginal stimulation. Despite moderate to low confidence in the evidence, large-scale RCTs are needed to evaluate long-term benefits of these treatment.
