Abstract
This study aimed to evaluate the efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). A search of PUBMED, EMBASE, Central Register of Controlled Trials (CENTRAL), Web of Science, Chinese Biomedicine Literature (CBM), China National Knowledge Infrastructure (CNKI), Wang-Fang Database, Chinese Scientific Journal Database (VIP), and other available resources was made for studies (up to February 2019). Searches were limited to studies published in English and Chinese. Only randomized controlled trials (RCTs) related to the efficacy and/or safety of acupuncture for CP/CPPS were included. Two investigators independently evaluated the quality of the studies. A total of 11 studies were included, involving 748 participants. The results revealed that compared with sham acupuncture (MD: -6.53 [95% CI: -8.08 to -4.97]) and medication (MD: -4.72 [95% CI: -7.87 to -1.56]), acupuncture could lower total NIH-CPSI score more effectively. However, there are no significant differences between acupuncture and sham acupuncture in terms of IPSS score. In terms of NIH-CPSI voiding domain subscore, no significant differences were found between acupuncture and medication. Compared with sham acupuncture (OR: 0.12 [95% CI: 0.04 to 0.40) and medication (OR: 3.71 [95% CI: 1.83 to 7.55]), the results showed favorable effects of acupuncture in improving the response rate. Acupuncture plus medication is better than the same medication in improving NIH-CPSI total score and NIH-CPSI pain domain subscore. In conclusion, the evidence suggests that acupuncture may be an effective intervention for patients with CP/CPPS. However, due to the heterogeneity of the methods and high risk of bias, we cannot draw definitive conclusions about the entity of the acupuncture's effect on alleviating the symptoms of CP/CPPS. The adverse events of acupuncture are mild and rare.
