GreenLight Photoselective Vaporization of the Prostate: One Laser for Different Prostate Sizes.

ABSTRACT

Introduction: GreenLight laser vaporization of the prostate (photoselective vaporization of the prostate [PVP]) is a safe and effective procedure for Benign Prostatic Hyperplasia. Long-term results and advantages of PVP in patients with large and symptomatic prostate are still under evaluation. Materials and Methods: In a multicenter experience, patients who underwent standard or anatomical PVP were retrospectively reviewed. Patients with follow-up >12 months were divided into two groups based on prostate volume (<100 cc vs ≥100 cc). Pre- and perioperative data, as well as postoperative results and complications, were recorded after 3, 6, and 12 months and then annually. Results: One thousand and thirty-one patients were eligible, 916 of these had a prostate volume of <100 cc and 115 ≥ 100 cc. Median follow-up period was 25.0 months (interquartile range [IQR] 16.5-35.0) and 16.0 months (IQR 12.0-24.0) in ≥100 and <100 groups, respectively. No difference was found in terms of catheterization time, postoperative stay, and postoperative acute urine retention. Patients with prostate ≥100 required longer operative time (75 vs 55 minutes), lasing time (41.7 vs 24.9 minutes), and higher energy used but lower energy density. Patients with prostate ≥100 had a higher incidence of early (50.4% vs 35.7%) and late complications (21.7% vs 12.8%) and early urge/incontinence symptoms (40.9% vs 29.3%). No statistically significant differences were found for the maximum urinary flow (Qmax) and International Prostate Symptom Score (IPSS) results between the two groups. The reintervention rate in ≥100 group was 3.5% vs 2.3% in <100. Conclusions: In the midterm follow-up, GreenLight PVP guarantees the same results in different prostate volume groups. Early and late complications are more frequent in large prostates.
