Purpose: We compared success rates of 3 surgical techniques (holmium laser enucleation of the prostate [HoLEP], transurethral resection of the prostate [TURP], and photoselective laser vaporization prostatectomy [PVP]) for treatment of benign prostatic obstruction (BPO). We aimed to identify preoperative clinical variables and urodynamic parameters that predict surgical success. Methods: A total of 483 patients who underwent surgical treatment for BPO at Samsung Medical Center between 2006 and 2017 were retrospectively analyzed; of these 361, 81, and 41 patients underwent HoLEP, TURP, and PVP, respectively. Prostate- specific antigen, prostate volume, urodynamic parameters, and International Prostate Symptom Score (IPSS)/quality of life (QoL) index were evaluated preoperatively; uroflowmetry, postvoid residual urine, and IPSS/QoL index were measured 6 months postoperatively. Surgical success was defined based on IPSS, maximum flow rate, and QoL index and predictive factors were identified using multiple logistic regression analyses. Results: Success rates of HoLEP, TURP, and PVP were 67.6%, 65.4%, and 34.1%, respectively, and the HoLEP and TURP groups were not significantly different. Regression analysis revealed prostate volume ≥50 mL and bladder outlet obstruction index (BOOI) ≥40 to be independent factors predicting HoLEP success. Only high preoperative QoL could predict the success of TURP, whereas other urodynamic parameters remained unrelated. Conclusions: Patients treated with HoLEP and TURP displayed equivalent efficacies, but PVP was relatively less efficient than both. Preoperative variables of prostate volume ≥50 mL and BOOI ≥40 were independent predictive factors for the success of HoLEP but not of TURP.
