Holmium laser enucleation versus bipolar transurethral enucleation for treating benign prostatic hyperplasia, which one is better?

Objective This study aims to evaluate the overall efficacy and safety between holmium laser enucleation of the prostate (HoLEP) and bipolar transurethral enucleation of the prostate (B-TUEP) for the treatment of benign prostatic hyperplasia (BPH). Method We systematically searched electronic databases (PubMed, Scopus, Web of Science, and Cochrane Library) to identify eligible comparative studies as of July 2021. The parameters including perioperative results, complications, and functional outcomes were evaluated. RevMan version 5.4 was used for the analysis. Results A total of 10 studies involving 1725 patients were included. HoLEP had lower operative time (p = .03), shorter catheterization time (p = .007), lower bladder irrigation time (p = .01), and higher enucleation weight (p = .01) compared with B-TUEP. However, there were no significant differences between the techniques regarding the length of stay (LOS), hemoglobin drop, transfusion rates, and complications. Furthermore, no significant differences were also observed in postoperative functional outcomes at 1, 3, 6, 12, or 24 months. Conclusions HoLEP has more advantages in perioperative parameters compared with B-TUEP, but no significant differences are found regarding functional outcomes and complications. Large-scale studies with long-term follow-up are required to compare the outcomes of these two techniques.
