    Abstract:
    INTRODUCTION: We systemically reviewed the current evidence on prostatic artery embolization (PAE) in treating men with benign prostatic hyperplasia. METHODS: A systemic literature search was conducted in PubMed, EMBASE and Web of Science on 1 May 2016 without time constraints. Outcomes of interest included the changes in the International Prostate Symptom Score (IPSS), quality-of-life (QOL) score, peak urinary flow (Qmax), post-void residual urine (PVR), International Index of Erectile Function (IIEF) score, prostate volume (PV) and prostate-specific antigen (PSA) level. RESULTS: A total of 987 records were identified through database searching. After removing duplicates, screening and reviewing full-length texts, a total of five records remained, with two randomized controlled trials and three non-randomized cohort studies. Transurethral resection of prostate resulted in better IPSS than PAE. Open prostatectomy had better IPSS, QOL score, Qmax and PVR, but worse IIEF score than PAE at 1 year. Unilateral PAE had higher rate of poor clinical outcome than bilateral PAE, but the difference became statistically insignificant after adjusting for age; IPSS, QOL score, Qmax, PVR, IIEF score, PV and PSA did not differ between the two groups. PAE with 100 μm PVA particles resulted in greater reduction in PSA level, but worse IIEF score than PAE with 200 μm PVA particles; IPSS, QOL score, Qmax, PVR, PV and poor clinical outcome did not differ between the two groups. CONCLUSION: Evidence on different aspects of PAE was limited. Further studies are warranted to investigate the role of PAE as compared to other forms of medical and surgical treatment.
