[Holmium laser ω-shaped pre-transection of prostate apex with preservation of the bladder neck improves urinary continence and sexual function in BPH patients after HoLEP].

Objective: To investigate the effect of holmium laser ω-shaped pre-transection of the prostate apex (PTPA) with preservation of the bladder neck on the urinary continence and sexual function of the patients with BPH after transurethral holmium laser enucleation of the prostate (HoLEP).

Methods: This retrospective study included 165 cases of BPH undergoing holmium laser ω-shaped PTPA with preservation of the bladder neck following HoLEP from January 2018 to January 2023. We recorded and compared the baseline, perioperative and 12-month follow-up data on the patients, and evaluated their urination function using IPSS, maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR), and quality of life (QOL) scores. For those who had had sexual activity and normal ejaculation before surgery, we further assessed their erectile and ejaculatory functions postoperatively.

Results: The mean surgical time was (70.35±12.27) min, the intraoperative blood loss (60.12±19.54) ml, and the weight of the excised gland (56.37±13.71) g. The hospital stay and postoperative catheter-indwelling time averaged (5.13±2.34) and (3.21±1.37) d, respectively. Significant improvements were observed in IPSS, QOL, PVR and Qmax at 3, 6 and 12 months after surgery compared with the baseline (P<0.05), which all remained stable throughout the follow-up period. At 3 months after surgery, stress urinary incontinence was found in 10.91% of the patients, and all but 1 case (0.6%) recovered within 12 months. There were no significant changes in the IIEF-5 and Erectile Hardness Scale (EHS) scores postoperatively (P>0.05). Retrograde ejaculation occurred in 19 (11.52%) of the patients, but none experienced painful ejaculation after surgery.

Conclusion: Holmium laser ω-shaped PTPA with preservation of the bladder neck is safe and effective for the treatment of BPH, which can effectively improve the urinary continence and protect the sexual function of the patient.
