GreenLight laser™ photovaporization of the prostate (GLL-PVP) has become a valid alternative to traditional transurethral resection of the prostate (TURP) in men requiring surgery for benign prostatic hyperplasia. 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.

Abstract

GreenLight laser™ photovaporization of the prostate (GLL-PVP) has become a valid alternative to traditional transurethral resection of the prostate (TURP) in men requiring surgery for benign prostatic hyperplasia. 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.
