80-W GreenLight Laser Vaporization Versus Transurethral Resection of the Prostate for Treatment of Benign Prostatic Obstruction: 5-Year Outcomes of a Single-center Prospective Randomized Trial

Published:February 12, 2018DOI:


      To assess long term functional and safety follow-up data after 80-W GreenLight photoselective vaporization (GL PV) of the prostate and transurethral resection of the prostate (TURP).

      Materials and Methods

      Prospective randomized trial at a single tertiary referral center (Geneva, Switzerland). Patients were recruited in the outpatient clinic if they met the criteria for surgical treatment of benign prostatic obstruction. At baseline, 238 patients were treated either with the 80-W GL PV or monopolar TURP. After 5 years, data were available from 105 patients: 44 GL PV patients and 61 TURP patients. The primary outcome measure was the International Prostate Symptom Score (IPSS). Secondary outcome measures included maximum urinary flow rate (Qmax), postvoidal residual (PVR) and reoperation rate. Statistical analyses were performed using Stata 14 (StataCorp).


      After 5 years of follow-up, mean improvements in International Prostate Symptom Score, postvoidal residual and maximum urinary flow rate were similar in both groups. The re-treatment rate was 14.3% in the GL PV group vs 11.9% in the TURP group (P = .9).


      Noninferiority of the GL PV to TURP was confirmed in all functional and safety outcomes at 5-year follow-up. GL-PV could be a safe surgical alternative for patients suffering from benign prostatic obstruction.
