To evaluate the safety and effectiveness of GreenLight 120-W laser photoselective vaporization of the prostate (PVP) versus transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).
We searched PubMed, Medline, Embase, Cochrane Library, Wanfang, CNKI, and VIP for randomized control trials and their references addressing 120-W PVP versus TURP in the treatment of BPH. Based on the inclusion and exclusion criteria, two reviewers independently accomplished the screening, quality assessment, and data extraction of the identified studies and performed meta-analyses using RevMan 5. 2.
Totally, 6 randomized control trials were included in this analysis, involving 703 cases, 351 treated by PVP and 352 by TURP. Compared with TURP, PVP showed significantly decreased time of catheterization (by 32. 55 hours, 95% CI 15. 3 -49. 8, P < 0. 01), hospital stay (by 1. 85 days, 95% CI 1. 2-2. 5, P < 0. 01), and intraoperative blood loss (by 15. 6 g/L, 95% CI 10. 0-21. 2, P < 0. 01), but increased time of operation (by 9. 37 minutes, 95% CI 5. 1-13. 6, P < 0. 01). There was also a significant reduction in blood transfusion, TUR syndrome, and capsular perforation in the PVP group. At 12 months after surgery, no statistically significant differences were found between the two groups in the improvement of maximum urinary flow rate, IPSS, postvoid residual, and sexual function.
GreenLight 120-W laser PVP is a safe and effective procedure for the treatment of BPH, with similar effectiveness to TURP but less blood loss, shorter time of catheterization and hospital stay, and lower incidences of blood transfusion, TUR syndrome and capsular perforation.
