The efficacy of green light laser prostatectomy in the management of urinary retention due to prostate hyperplasia

To evaluate the efficacy and safety of 120 W potassium titanyl phosphate (KTP) in the treatment of urinary retention (UR) due to benign prostate hyperplasia in high-risk patients. Forty-six male patients with mean age of 73.78 ± 9.82 years who اhad UR and underwent 120 W KTP laser vaporization of the prostate between January 2015 and June 2017 were included. We evaluated perioperative parameters including serum prostate specific antigen, prostate volume, period of postoperative catheterization, vaporization time, delivered energy, hospitalization period, as well as intraoperative and postoperative complications. In the follow-up protocols, International Prostate Symptom Score and quality-of-life questionnaire (IPPS-QoL) and postvoid residual volume (PVR) were also assessed. The mean follow-up period was 15.57 ± 9.26 (1–42) months. All patients get rid of UR, except 1 patient (2.1%) remained on Foley catheter and standard TURP was done. Mean vaporization time was 8.57 ± 4.19 min, and mean energy delivered was 51.7 ± 29.9 kJ. No intraoperative complications were observed and no blood transfusion was done. The mean postoperative IPSS at the last follow-up was 9.64 ± 6.65 and the QoL score was 1.61 ± 1.31. Green light laser prostatectomy is a safe, simple, and effective procedure for the treatment of UR secondary to BPH in high-risk patients. Short hospitalization, low rate of intra operative and postoperative complications with rapid improvements in the objective, and subjective voiding parameters are important considerations of this procedure.
