Comparison of the short-term efficacy and safety of bipolar transurethral electro vaporization and holmium laser enucleation of the prostate for moderate and large benign prostatic enlargement

Abstract

Abstract Background To compare the efficacy and safety of bipolar transurethral vaporization of the prostate (B-TUVP) with holmium laser enucleation of the prostate (HoLEP) for moderate [prostate volume (PV) 30–80 ml] and large (≥ 80 ml) benign prostatic enlargement (BPE). Materials and methods Male patients with lower urinary tract symptom (LUTS) or urinary retention who underwent B-TUVP or HoLEP treatment in two regional centers were respectively enrolled. Patient characteristics and treatment outcomes were retrospectively compared between B-TUVP and HoLEP. Results In patients with moderate and large prostate volume,B-TUVP showed shorter operative time (P 80 ml.(P 80 ml.(P=0.08) The Incidence of postoperative stress incontinence(SUI) was higher in HoLEP than in B-TUVP for patients with moderate and large prostate volume. Conclusions There are few studies that investigated the short-term efficacy and safety of second-generation B-TUVP in comparison with HoLEP for moderate and large BPE. Improvement in LUTS and achievement of catheter-free status were predominant in HoLEP, and these outcomes were more prominent in patients with large BPE of PV > 80 ml. However, B-TUVP resulted in less blood loss, shorter operative duration, and less SUI suggesting that B-TUVP is also well-tolerated surgical modality.
