PD21-05 SINGLE-CENTER EXPERIENCE UTILIZING SECOND GENERATION AQUABEAM SYSTEM FOR THE TARGETED, HEAT-FREE REMOVAL OF PROSTATE TISSUE, DURING THE TREATMENT OF BPH

achieved 30% reduction in symptoms. Qmax increased 68% (6.2 ml/ s) at 3 months vs. no change in controls (p u003c0.0001). These improvements were sustained in 96% of treated subjects who completed their 1year follow-up (pu003c0.0001). At study entry, 52% of treatment subjects had a history of erectile dysfunction (ED) and 26% had decreasedstoppage ejaculation. Only sexually active men (91/136) 67% were included in the sexual function analyses. In these, the IIEF-EF baseline mean was 17.2 (30 max score) and the MSHQ-EjD mean was 7.8 (15 max). There were no clinically meaningful negative changes in scores over 12 months. Modest decreases in ejaculatory volume occurred in 6 men (4.4%), anejaculation in 4 men (2.9%). No de novo ED was reported. CONCLUSIONS: Conservation of sexual function is a fundamental QOL issue for men contemplating a nonsurgical treatment options for LUTS/ BPH. Convective water vapor thermal energy therapy is a minimally invasive treatment that provides rapid and durable LUTS improvements and no clinically significant changes in erectile and ejaculatory function. The thermal energy treatment was developed for in-office use and shown to be applicable to treatment of all prostate zones including median lobes.
