23 months postoperatively are in line with results from other greenlight and TURP series. Prostate volume ≥
100 mL, preoperative urethral stricture, and the early-onset complications correlate with the re-treatment
risk. Greenlight PVP has good functional long/mid-term results. The presence of preoperative urethral
stricture and the occurrence of early complications correlate with the risk of late re-treatment. In patients
with prostate ≥ 100 mL, the enucleation technique may be superior to vaporization in terms of lower long-
term risk of re-intervention for a LUTS relapse.
