Abstract:
PURPOSE: To evaluate the effect of preoperative 5-alpha reductase inhibitor (ARI) administration on the operative results of photoselective vaporization of prostate with 120W GreenLight HPS laser. MATERIALS AND METHODS: Data were collected from 98 benign prostatic hyperplasia (BPH) patients who underwent transurethral electrovaporization of prostate by 120W Greenlight HPS laser between Jan. 2010 and Dec. 2010. We compared the time of operation, the energy required in lasering, postoperative maximum uroflow velocity, change in residual urine volume and complications between 5-ARI administrating group and control group. RESULTS: 56 patients administrated 5-ARI at least 3 months before surgery. 30 and 26 patients administrated finasteride and dutasteride, respectively. Mean follow up period was 4.1+/-1.8 months. Mean age of the subjects and mean prostate volume were not different. Mean change of postoperative hemoglobin, lasing time and energy required in lasering were greater in 5-ARI administrating group. There were 3 and 1 cases of acute urinary retension in 5-ARI administrating group and control group, respectively. CONCLUSIONS: The mean change of hemoglobin and mean energy required in lasering were greater and mean lasing time was longer in the patients who administrated 5-ARI before photoselective vaporization of prostate by 120W Greenlight HPS laser. Further investigation and extensive study will be needed to confirm these results.
