We aimed to review systematically the safety and efficacy of studies comparing GLL PVP and TURP in the medium-term. A comprehensive literature search was performed. Twelve studies were identified for meta-analysis. Meta-analyses showed a longer postoperative catheterization time (risk ratio (RR): 1.12, 95% CI:1.09– 1.14, p< 0.00001) and length of stay (RR: 1.16, 95% CI:1.12– 1.19, p< 0.00001) in the TURP group; higher risk of transfusion in the TURP group (RR: 6.51, 95% CI: 2,90– 14,64 p< 0.00001); no difference in the risk of urinary tract infections (RR: 0.83, 95% CI: 0.58– 1.18, p=0.30) and transient re-catheterization (RR: 1.11, 95% CI: 0.76– 1.60, p=0.60). Regarding reoperation rate, no difference was found in term of postoperative urethral stricture (RR: 1.13, 95% CI: 0.73– 1.75, p=0.59) and bladder neck contracture (RR: 0.66, 95% CI: 0.31– 1.40, p=0.28). A significantly higher incidence in reoperation for persistent/regrowth adenoma was present in the GLLL-PVP (RR: 0.64, 95% CI: 0.41– 0.99, p=0.05). Data at 2-year follow-up showed significant better post-voiding residual (PVR) (MD: -1.42, 95% CI: -2.01, -0.82, p< 0.00001) and International Prostate Symptom Score (IPSS) (MD: -0.35, 95% CI: -0.50, -0.20, p< 0.00001) after TURP. No difference was found in the mean PVR at 2 years after TURP, in the mean maximum flow rate (Qmax) (MD: 0.30, 95% CI: -0.02– 0.61, p=0.06) and quality of life QoL score (MD: 0.05, 95% CI: -0.02– 0.42, p=0.13). At 5-year follow-up, data showed better IPSS (MD: -1.70, 95% CI: -2.45,-0.95, p< 0.00001), QoL scores (MD: -0.35, 95% CI: -0.69, -0.02, p=0.04) and Qmax (MD: 3.29, 95% CI: 0.19– 6.38, p=0.04) after TURP. Data of PVR showed no significant difference (MD: -11.54, 95% CI: -29.55– 6.46, p=0.21). In conclusion, our analysis shows that GLL-PVP is a safer and more efficacious procedure than standard TURP in the early and medium-term. However, in the long term period GLL-PVP showed a higher incidence of reoperation rate due to incomplete vaporization/regrowth of prostatic adenoma.Keywords: benign prostatic hyperplasia, GreenLight laser photoselective vaporisation of the prostate, transurethral resection of the prostate, safety, efficacy, transurethral surgery
