Holmium laser enucleation of the prostate versus bipolar transurethral enucleation of the prostate in management of benign prostatic hyperplasia: A randomized controlled trial

Abstract

To evaluate the safety, efficacy and cost-effectiveness of holmium enucleation of the prostate and bipolar transurethral enucleation of the prostate. In our randomized controlled trial, 120 patients were allocated into two equal groups representing holmium enucleation of the prostate and bipolar enucleation of the prostate. Operative parameters were recorded according to operative, enucleation and resection time in addition to the intraoperative complications. Patients were followed up at 1, 3 and 12months postoperative to assess the prostate size, post-voiding residual urine, International Prostate Symptom Score, peak urine flow rate and quality of life, and compared with the preoperative parameters. Cost analysis was evaluated for both procedures. We evaluated 107 patients who finished our follow up and their data were analyzed. The prostate size was 135.2±34.8mL and 125±26.9mL for holmium enucleation of the prostate and bipolar enucleation of the prostate, respectively. Holmium enucleation of the prostate was associated with a shorter operative time of 83.43±6.92min compared with 94.7±12.2min in bipolar enucleation of the prostate groups. Holmium enucleation of the prostate was associated with an earlier catheter removal time and shorter hospital stay compared with bipolar enucleation of the prostate. Postoperative International Prostate Symptom Score, quality of life, post-voiding residual urine, peak urine flow rate, prostate-specific antigen and prostate volume reduction were comparable between both groups, and they both showed statistically significant improvement compared with their preoperative parameters. In the cost analysis, holmium enucleation of the prostate was more cost-effective than bipolar enucleation of the prostate. Both holmium enucleation of the prostate and bipolar enucleation of the prostate are safe and effective in the surgical management of large prostatic adenomas. Holmium enucleation of the prostate has a shorter operative time and hospital stay with earlier catheter removal time, and is more cost-effective than bipolar enucleation of the prostate.
