[Efficacy and safety of low-intensity extracorporeal shock wave therapy in the treatment of ED: A meta-analysis of randomized controlled trials].

Objective To evaluate the clinical efficacy and safety of low-intensity extracorporeal shock wave therapy (LI-ESWT) in the treatment of ED based on the available clinical evidence. Methods We searched PubMed, MEDLINE, EMBASE, Cochrane Library, CNKI, VIP, CBM and Wanfang Database up to June 2018 for published randomized controlled trials on the treatment of ED by LI-ESWT. We performed literature screening, data extraction and quality evaluation according to inclusion and exclusion criteria, and conducted a meta-analysis of the data obtained using the RevMan 5.3 software. Results A total of 595 ED cases in 8 double-blind randomized controlled trials (RCT) were included in this study, 362 in the LI-ESWT and 233 in the control group. Compared with the controls, the patients treated by LI-ESWT showed significantly improved IIEF (WMD = 1.70, 95% CI: 0.44－2.96, P = 0.008) and erection hardness score (EHS) (RR = 11.72, 95% CI: 5.13－26.80, P Conclusions As a non-invasive treatment, LI-ESWT is safe and effective and can significantly improve IIEF and EHS in ED patients.
