ED appears to be related to adequate tissue removal and probably improved mid-term outcomes in patients treated with photo-vaporization (PVP) of the prostate with GreenLight laser. We aim to assess associated factors with a lesser ED delivery in prostate photo-vaporization. METHODS: Data was retrospectively collected from a single center database with 748 patients who underwent surgery between 2012 and 2019. Groups were divided according to intra-operative energy delivered to the prostate. Group 1: < 4.0 and group 2: ≥4.0 kJ/mL. Peri and postoperative outcomes were assessed. Bivariate and multivariate analyses were performed to determine the statistically significant variables associated with the use of low ED. RESULTS: General characteristics are shown in Table 1. Group 1 had a total of 36% (n=268), and Group 2 had 64% (n=480) patients. Bivariate analysis was performed, and statistically significant association was observed for higher PV (OR=1.02 [1.02-1.01] IC 95% p-value <0.01), history of combination therapy (OR=1.5 [2-1.1] IC95% p-value=0.01) and postoperative longer bladder catheterization time. After controlling by confounding variables, the multivariate analysis showed that for patients with lower ED delivered acute urinary retention (AUR) appeared to be a protective factor (OR=0.6 [0.9-0.4] IC95% p-value=0.01), and a larger prostate volume (OR=1.02 [1.3-1.02] IC95% p-value <0.01) was associated with lesser ED. CONCLUSIONS: After analyzing factors like surgeons' expertise and comorbidity, we found that PV is shown to be associated with lower energy density delivery and potentially associated with worse functional outcomes.
