[Monoplane versu biplane holmium laser enucleation of the prostate for the treatment of large-volume benign prostatic hyperplasia].

Objective To compare the clinical effect and safety of monoplane holmium laser enucleation of the prostate (MP-HoLEP) from those of biplane HoLEP (BP-HoLEP) in the treatment of large-volume BPH. Methods We retrospectively analyzed the clinical data on 67 cases of large-volume BPH treated in Jintan People's Hospital from June 2017 to December 2018, 30 by MP-HoLEP with incisions at 5- and 7-o'clock positions beside the verumontanum and the other 37 by BP-HoLEP with incision at 12 o'clock in the bladder neck to expose the surgical capsule layer. We compared the perioperative, postoperative and follow-up data between the two groups of patients. Results There were no statistically significant differences between the two groups of patients in the age, disease course, prostate volume or preoperative post-void residual urine volume (PVR), maximum urine flow rate (Qmax), IPSS, PSA level and quality of life score (QOL). Compared with the patients in the MP-HoLEP group, those treated by BP-HoLEP showed a significantly shorter operation time (［97.65 ± 34.72］ vs ［125.46 ± 47.58］ min, P 0.05). PVR, Qmax, IPSS and QOL were improved similarly in both of the groups at 6 months postoperatively. Conclusions Both MP-HoLEP and BP-HoLEP are definitely effective for the treated of large-volume BPH, but the latter is superior to the former for shorter operation and enucleation time and less bleeding.
