This study aimed to evaluate the efficacy and safety of holmium laser enucleation of prostate (HoLEP) by using en-bloc and bladder neck preservation technique on benign prostatic hyperplasia (BPH) and assess the influence of this procedure on urinary and sexual functional outcomes.
A total of 704 patients with BPH undergoing HoLEP were retrospectively analysed. Amongst them, 213 who met the sexual function assessment criteria were further assessed the influence of the technique on sexual functional outcomes.
The mean operative time, resected prostate weight and mean estimated blood loss were 69.3±14.8 min, 53.4±17.6 g and 62.1±23.7 mL, respectively. The mean duration of catheterization after surgery and mean hospital stay were 2.1±1 and 5.4±3.6 days, respectively. The post-void residual volume, maximum urinary flow rate, international prostate symptom score and quality of life score were all significantly improved postoperation (P<0.05). Amongst the 213 patients with normal antegrade ejaculation before surgery, postoperative international index of erectile function scores slightly improved, although the difference was insignificant (P>0.05). The difference in the Erection Hardness Grading Scale before and after surgery was statistically insignificant (P>0.05). A total of 25 (11.7%) patients had retrograde ejaculation after surgery.
HoLEP by an en-bloc and bladder neck preservation technique can obtain good functional outcome with small injury and high efficiency, especially for patients who need to preserve normal sexual function and anterograde ejaculation.
