  • Introduction:

      In this study, we sought to investigate the impact of 5-alpha reductase inhibitors (5-ARI) on the perioperative and functional outcomes of 180-Watt XPS GreenLight photovaporization of the prostate (PVP) using a large international database.

    Materials and methods:

      Data were obtained from the Global GreenLight Group (GGG) database, which includes eight high-volume, experienced surgeons from seven international centers.  All men with established benign prostatic hyperplasia (BPH) with known 5-ARI status who underwent GreenLight PVP using the XPS-180W system between 2011 and 2019 were eligible for the study.  Patients were assigned to two groups based on the preoperative use of 5-ARI.  Analyses were adjusted for patient age, prostate volume, and American Society of Anesthesia (ASA) score.


      We included 3,500 men, of which 1,246 (36%) had preoperative 5-ARI use.  Patients in both groups were similar with regards to age and prostate size.  On multivariable analysis, total operative time was slightly shorter (-3.26 min 95% CI: 1.20 — 5.32, p < 0.01) and required 35.6kJ less laser energy (95% CI: -48.0kJ — -23.3kJ, p < 0.01) for patients on 5ARI compared to those without 5-ARI.  However, no clinically significant difference was appreciated regarding postoperative transfusion rates [OR 0.048 (95% CI -0.82-0.91; p = 0.91)], hematuria rates [OR 0.96 (95% CI 0.72-1.3; p = 0.81)], 30-day readmission rates [OR 0.98 (95% CI 0.71-1.4; p = 0.90)], or overall functional outcomes.


      Our findings suggest that preoperative 5-ARI is not associated with any clinically significant different perioperative or functional outcomes for GreenLight PVP using the XPS-180W system.  There is no role for the initiation or discontinuation of 5-ARI prior to GreenLight PVP.
