Efficacy of acupuncture for urinary incontinence in middle-aged and elderly women: A systematic review and meta-analysis of randomized controlled trials

Objectives: Our aim was to generalize the available evidence and evaluate the effectiveness of acupuncture for urinary incontinence in middle-aged and elderly women. Methods: Six databases including VIP, CNKI, Wan Fang, Web of Science, PubMed and The Cochrane Library were systematically searched to retrieve similar studies updated to December 2019 to gather RCTs regarding the effectiveness of acupuncture for middle-aged and elderly women with urinary incontinence. Two researchers independently performed the whole process of retrieving the studies, extracting the data and assessing the risk of bias of the included studies. The current meta-analysis was performed using RevMan 5.3 software. Results: A total of eight studies with 607 patients were included in the evaluation. The current meta-analysis showed that Compared with rehabilitation exercise or medication, acupuncture intervention significantly improved the clinical effectiveness (OR = 5.52, 95 % CI, 3.13-9.73), reduced the urine leakage in pad test (SMD = -2.67, 95 % CI, -4.05 to -1.29) and decrease the ICIQ-SF score (MD = -3.46, 95 % CI, -3.69 to -3.22). The results indicated that acupuncture intervention can help the patients alleviate the symptoms effectively. Conclusion: Based on this study, acupuncture intervention of stress urinary incontinence in middle-aged and elderly women can improve the clinical effectiveness, reduce the urine leakage in pad test and ICIQ-SF score. More high-quality studies with large sample size are required for further verification. (C) 2020 Elsevier B.V. All rights reserved.
