Abstract

Objective: We assessed the effectiveness and durability of 532 nm laser photovaporization with GreenLight XPS in men with and without preoperative urinary retention. Materials and Methods: 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. Results: 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 < 0.001), had a higher American Society of Anesthesiology (ASA) score, and had a higher prevalence of neurologic disease (8% vs 2.6%; p = 0.04). These men also had a larger prostate volume (76 cc vs 69 cc; p < 0.001) and higher prostate specific antigen (5 ng/mL vs 2.7 ng/mL; p < 0.001) than those without retention. Patients with preoperative retention also had higher preoperative baseline IPSS and QoL score. After PVP they improved to values similar to those without retention, with durability up to 24 months. After PVP, men in preoperative retention had similar rates to fail their first void trial (18.2% vs 10.3%, p = 0.053). There was a 96% catheter-free rate in the men with preoperative retention. The rate of complication was higher in the nonretention group, specifically at 90 days (35.4% vs 21.2%; p = 0.009), with almost all the complications being Clavien-Dindo grade 2. Conclusion: PVP is an effective, safe, and durable treatment for men in acute urinary retention (AUR) with a catheter-free rate of 96%. The improvement is similar to those who did not present in AUR.
