ObjectivesTo systematically evaluate the efficacy and safety of 1 470 nm laser vaporization vs. transurethral resection of prostate (TURP) for benign prostatic hyperplasia (BPH).MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) about the efficacy and safety of 1 470 nm laser vaporization vs. TURP for BPH from inception to October 22nd, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 6 RCTs and 4 non-RCTs were included. The results of meta-analysis showed that: 1 470 nm laser vaporization was superior to TURP in reducing intraoperative bleeding (MD=−103.87, 95%CI −148.08 to −59.65, P<0.000 01), hospital stay (MD=−3.82, 95%CI −4.35 to −3.28, P<0.000 01), postoperative indwelling catheter time (MD=−2.24, 95%CI −3.45 to −1.02, P=0.000 3), postoperative hemoglobin (MD=−1.63, 95%CI −3.14 to −0.12, P=0.03) and rate of secondary hemorrhage (OR=0.13, 95%CI 0.03 to 0.48, P=0.002). There were no significant differences in operative time, bladder irrigation time, transient urinary incontinence and urethral stricture, IPSS Score and Qmax at 3 months after operation between the two groups (P>0.05).ConclusionCurrent evidence shows that 1 470 nm laser vaporization is superior to TURP in reducing intraoperative bleeding and secondary hemorrhage. It may be more suitable for prostate surgery in anticoagulant or coagulative dysfunction patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
