Vaporization of Prostate by 160W GreenLight Laser on Postoperative Erectile Function - A Single center report.

OBJECTIVE To evaluate the impact of photoselective vaporization of the prostate (PVP) on erectile function (EF) utilizing a 160W GreenLight laser system with up to 36 months of follow-up in men with lower urinary tract symptoms caused by benign prostatic hyperplasia. METHODS A prospectively maintained database of patients who underwent GreenLight PVP was retrospectively reviewed. International Index of Erectile Function-5 (IIEF-5) questionnaire was used to assess EF. In total, 265 sexually active patients who underwent 160W GreenLight laser PVP were identified and divided into Group A with baseline IIEF-5 <19 and group B with baseline IIEF-5 >= 19. IIEF-5, International Prostate Symptom Score, quality of life, postvoid residual, and Qmax were recorded preoperatively, perioperatively, and at follow-up after 1, 3, 6, 12, 24, and 36 months. Recorded data were analyzed statistically using t- and chi(2) tests. RESULTS The preoperative and perioperative data of the 2 groups were comparable. Significant improvements in International Prostate Symptom Score, Qmax, quality of life, and postvoid residual were observed in both groups at every follow-up visit throughout the 36 months with no significant difference between the groups. EF was sustained postoperatively compared with the baseline in the whole study population. In Group A (preoperative IIEF-5 <19), EF was significantly improved at 1 month and 12 month (P= .02 and P= .002). CONCLUSION In patients undergoing PVP by 160W GreenLight laser for lower urinary tract symptoms secondary to benign prostatic hyperplasia, no significant detrimental effect was observed in the EF at up to 3 years of follow-up. However, in patients with preoperative erectile dysfunction (ED), we showed a significant improvement. (C) 2019 Elsevier Inc.
