Effects of Changes in Erectile Function After Holmium Laser Enucleation of the Prostate on Postoperative Outcomes in Patients With Benign Prostatic Hyperplasia.

Background/aim: Sexual function in patients with benign prostatic hyperplasia (BPH) could be affected by surgical intervention, such as holmium laser enucleation of the prostate (HoLEP). The objective of the present study was to investigate whether changes in erectile function (EF) after HoLEP affect postoperative outcomes in patients with BPH.

Patients And Methods: We retrospectively reviewed 54 consecutive Japanese patients with BPH undergoing HoLEP at our institution between August 2017 and December 2020, and analyzed data obtained before and 6 months after HoLEP, including the Erection Hardness Score (EHS), International Prostate Symptom Score (IPSS), IPSS-Quality of Life (IPSS-QOL), Overactive Bladder Symptom Score (OABSS), and the Medical Outcomes Study 8-Item Short-Form Health Survey consisting of a mental health component summary (MCS) and physical health component summary (PCS).

Results: Although no significant differences were observed between preoperative and postoperative EHS, postoperative EHS deteriorated in 19 out of 54 patients. Total IPSS, IPSS-QOL, and OABSS significantly improved after HoLEP, irrespective of the deterioration of EHS; however, despite the lack of significant changes in MCS and PCS in 19 patients with deteriorated EHS, significant improvements in MCS, but not PCS, were postoperatively observed in the remaining 35. A multivariable analysis of several factors identified a preoperative estimated prostate volume >100 cm as an independent risk factor associated with the postoperative deterioration of EHS.

Conclusion: HoLEP had limited impact on postoperative EF in BPH patients; however, favorable QOL may be expected in patients without the postoperative deterioration of EF. Accordingly, it may be important to consider the prostate volume and its effect on postoperative EF when selecting indications for HoLEP.
