[Clinical Outcomes of Anteroposterior Dissection Holmium Laser Enucleation of the Prostate for Benign Prostatic Hyperplasia]

Holmium laser enucleation of the prostate (HoLEP) is a standard surgical procedure for treatment of benign prostatic hyperplasia (BPH). A low incidence of postoperative urinary incontinence in association with anteroposterior dissection HoLEP was recently reported. We evaluated 66 patients with BPH who underwent anteroposterior dissection HoLEP from March 2013 to November 2014. The International Prostate Symptom Score (IPSS), quality of life (QOL) index, maximum flow rate (Qmax), and post-void residual urine volume (PVR) were assessed preoperatively and at 1 and 3 months after treatment. The incidence of postoperative urinary incontinence, which was defined as the requirement of more than one pad per day, was compared between the first and second half of the patient population. Postoperative urination parameters (IPSS, QOL index, Qmax, and PVR) were significantly improved. The incidence of urinary incontinence at 3 months was significantly lower in the second half (4%) than first half (28%) of the patient population (p＝0.020). In conclusion, anteroposterior dissection HoLEP is an effective procedure for the treatment of BPH and can reduce the rate of postoperative urinary incontinence, even in low-volume institutes.
