Background: Prostatic artery embolization (PAE) in the treatment of benign prostatic hyperplasia (BPH) has been introduced into clinical practice, but conclusive evidence of efficacy and safety has been lacking. Objective: To compare the efficacy and safety of prostatic artery embolization (PAE) vs. transurethral resection of prostate (TURP), we performed a meta-analysis of clinical trials. Methods: We searched randomized controlled trials (RCTs) from Pubmed, Embase, Wanfang, and CNKI from January 2000 to December 2020 and used RevMan 5.0 to analyze the data after five RCTs were included. Results: The reducing of prostate volume (PV) [Median mean (MD) 14.87; 95% confidence interval (CI) 7.52-22.22; P < 0.0001] and the increasing of maximum flow rate in free uroflowmetry (Qmax) (MD 3.73; 95% CI 0.19-7.27; P = 0.004) were more obvious in TURP than in PAE; however, the rate of lower sexual dysfunction [odds ratio (OR) 0.12; 95% CI 0.05-0.30; P < 0.00001] was lower in PAE compared with TURP. Meanwhile, no conspicuous difference in International Prostate Symptoms Score (IPSS) score (MD 1.42; 95% CI -0.92 to 3.75; P = 0.23), quality of life (Qol) score (MD 0.21; 95% CI -0.31 to 0.73; P = 0.43), post void residual (PVR) (MD 21.16; 95% CI -5.58 to 47.89; P = 0.12), prostate-specific antigen (PSA) (MD 0.56; 95% CI -0.15 to 1.27; P = 0.12), and complications (OR 0.90; 95% CI 0.20-4.05; P = 0.89) between PAE and TURP group was shown. Conclusion: PAE may replace TURP as an alternative treatment for Benign prostatic hyperplasia (BPH) patients who do not want to have surgery or with operational contraindications.
