MP01-16 IMPACT OF ENERGY DENSITIY ON FUNCTIONAL OUTCOMES AFTER PHOTOVAPORIZATION OF THE PROSTATE WITH GREENLIGHT™ 180W XPS LASER. DOES IT MATTER?

INTRODUCTION AND OBJECTIVES:Energy density (ED) measures the optimization of laser use in relation to prostate volume (PV). This seems to be related with adequate tissue removal and improved long terms outcomes in patients who are being treated with prostate photovaporization (PVP). Is not clear which range of ED should be provided to guarantee safe and durable results. Our aim is to assessED (kJ/mL) on functional outcomes and complications.METHODS:Data were retrospectively collected from a referral center between 2012 and 2017. Three groups of ED were stratified according to intra-operative energy delivered to the prostate. Group 1: ≤3.0; group 2: 3.0 - 5.0 and group 3: >5.0 kJ/mL. Functional outcomes as PSA drop, IPSS improvement (defined as a drop of ≥4 points), quality of life (QoL) and symptomatic improvement (VAS) were estimated. Peri and postoperative outcomes were assessed with Clavien-Dindo classification. Descriptive and inferential statistics were used.All analyses were performed using 24.0 SPS...
