Efficacy, Safety, and Durability of 532 nm Laser Photovaporization of the Prostate with GreenLight 180 W XPS in Men with Acute Urinary Retention

We assessed the effectiveness and durability of 532 nm laser photovaporization with GreenLight XPS in men with and without preoperative urinary retention. From 2010 to 2017 we prospectively studied men who underwent photovaporization of the prostate (PVP) for obstructive lower urinary tract symptoms (LUTS) secondary to BPH. The cohort was retrospectively divided into those with catheter dependent retention and those with elective PVP. Primary endpoints were catheter-free rate and improvement in quality of life (QoL) scores, international prostate symptom score (IPSS), maximum urinary flow rate (Qmax), and postvoid residual (PVR). The secondary endpoints of the study were complication outcomes as defined by the standardized Clavien-Dindo grading system. One hundred thirty-seven men with preoperative retention and 195 men without preoperative retention underwent PVP. Men with preoperative retention were older (70 years vs 66 years; p
