Abstract
PURPOSE: To asses the (1) outcomes and (2) intraoperative, perioperative, and long-term complications of photoselective vaporization of the prostate (PVP) with Greenlight laser. METHODS: A systematic review of outcomes and complications of PVP was conducted. The article selection process was performed according to PRISMA guidelines and included publications published between 2009 and 2014. RESULTS: All generations of PVP (80, 120, 180 W) lead to a significant improvement of micturition symptoms (IPSS, QoL) and voiding parameters (Q max, PVR volume) during follow-up. Data on sexual function are heterogeneous and suggest a trend toward decline in erectile function in men with sustained preoperative erection. The rate of intraoperative complications is low. Data on peri- and postoperative complications show a large variation that mainly can be attributed to heterogeneity in documentation. CONCLUSIONS: PVP leads to a statistically significant and clinically relevant improvement of voiding parameters and micturition symptoms in patients with prostates <100 ml. The technique is characterized by a high degree of intra- and perioperative safety. Long-term evidence on functional outcomes and complications beyond 3 years from RCTs is currently missing for all generations of the Greenlight laser.
