- Abstract
This study aimed to evaluate the impact of thulium:yttrium-aluminum-garnet (Tm:YAG) (RevoLix®) laser prostatectomy for the treatment of benign prostatic obstructions on erectile function (EF). A total of 208 patients who underwent Tm:YAG laser prostatectomies participated in this study. All cases were evaluated preoperatively and at 3, 6, and 12 months postoperatively using the International Prostate Symptom Score (IPSS), quality of life (QoL) score, and the International Index of Erectile Function (IIEF-5) questionnaires. Patients were divided into groups A (severe erectile dysfunction [ED]), B (moderate ED), and C (mild-to-normal ED), according to their IIEF-5 scores. The median patient ages were 69, 65, and 62 years in groups A, B, and C, respectively. Significant improvements occurred in the IPSS and QoL score within the groups during the 12-month follow-up period. The IIEF-5 scores at 3 months postoperatively were lower than the preoperative scores in groups B and C. The IIEF-5 scores subsequently improved during the 12-month follow-up period. The slope of the relationship between the IIEF-5 score and the time since Tm:YAG laser prostatectomy had a ß value of 0.2210 (95% confidence interval 0.103 to 0.338, p = 0.0003); hence, each postoperative month was associated with an increase of 0.2210 in the IIEF-5 score. The IIEF-5 scores gradually increased and reached the preoperative levels by the 12-month follow-up assessment. Although the IIEF-5 score dropped significantly during the first 3 months postoperatively, it improved over the following 12 months. Tm:YAG laser prostatectomy did not impact on EF ultimately.
