• To investigate 5-year long-term postoperative efficacy in benign prostate hyperplasia (BPH) following 120-W GreenLight high-performance system photoselective vaporization of the prostate (HPS-PVP). This was a retrospective study of surgical outcomes in 159 men who underwent HPS-PVP and were followed over 60 months postoperatively. Definitions of treatment success were established based on the following three variables: international prostate symptom scores (IPSS), maximum flow rates (Qmax), and quality of life scores QoL). Logistic regression analyses were performed to determine predictors of the postoperative success. Postoperative IPSS/QoL, Qmax and post-voided residual urine volume were significantly improved after HPS-PVP. Postoperative Prostate specific antigen and prostate volume were also well reduced and sustained for 5 years. The postoperative success rate was assessed as 82.1%, 80.8% and 76.1% for each 1-, 3-, and 5-year. Thirty-eight (23.9%) patients had immediate postoperative complications, which were managed successfully with nonsurgical methods. None required transfusions, two (1.2%) patients required endoscopic reoperation for postoperative voiding difficulty due to bladder neck contracture or urethral stricture, and five (3.1%) required HPS-PVP reoperation. Presence of diabetes, voiding symptom subscore, QoL, maximal cystometric capacity, and bladder outlet obstructive index were valuable preoperative parameters for predicting postoperative success. HPS-PVP is an effective, long-term treatment option for BPH, with sustained efficacy of 76.1% at 5-year follow up. Several preoperative parameters could help to predict the durable surgical improvements.
