Electroacupuncture for urinary retention after stroke: A systematic review and meta-analysis of randomized controlled trials.

ABSTRACT

BACKGROUND AND PURPOSE: Electroacupuncture (EA) is one of the non-pharmacological therapies in traditional Chinese medicine to treat urinary retention. The objective of this meta-analysis is to assess the efficacy of electroacupuncture in the treatment of urinary retention after stroke. METHODS: Overall, seven electronic databases were searched until December 31, 2023, and randomized control trials about EA for urinary retention after stroke were reviewed. Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias for included studies. The meta-analysis was conducted by RevMan 5.4 and Stata/MP 17.0 software. RESULTS: Eleven studies with a total of 856 participants were included in this meta-analysis. EA treatment yielded an improved reduction in the post-void residual (PVR) (mean difference [MD] 37.85, 95 % confidence interval [CI] 55.09 to -20.61 p < 0.0001) and the weight of diaper pads (MD 38.87, 95 % CI 42.68 to -335.06). Further analysis indicated that EA improved the effectiveness ratio (risk ratio [RR] 1.36, 95 % CI 1.20 to 1.53, p < 0.00001), the function of the bladder (MD 0.45, 95 % CI 0.61 to -0.30), and the quality of life (MD 1.15, 95 % CI 2.10 to -0.20) in comparison to normal treatment and simple acupuncture. CONCLUSION: EA may be an effective way and reasonable modality to incorporate into the multiple prevention and therapy for urinary retention after stroke. The wide application of EA could be associated with the improvement of bladder and life quality and decline in the PVR for patients after stroke with urinary retention.
