Objective
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).
Results
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).
Conclusion
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.
