Objective: To improve HoLEP surgical techniques of finding envelope,enucleation,hemostatic and comminufion,and to treate the incontinence reason predictably,so as to reduce the complications of HoLEP surgery.Methods: Technical improvements were performed in 272 patients who underwent HoLEP during January 2014 to December 2014.(Ⅰ)The gland was enucleated in three lobes,not overall enucleation;(Ⅱ)start with both sides of verumontanum to find envelope,thethree-lobetechnique involves 5-and 7-oclock position incisions with enucleation of the middle lobe and subsequent enucleation of one lateral lobe followed by the other lateral lobe;(Ⅲ)we only lift the glands gently by lens body,using holmium laser blasting to peel glands,and abandon conventional mirror peeling method;(Ⅳ)if bleeding is encountered,the laser fibre can be defocused slightly from the bleeding point to achieve haemostasis;(Ⅴ)we crushed glands vacantly with the status of bladder filling.The reason why postoperative urinary incontinence occurs may be thermal burns sphincter,mucosal retention inadequate,sphincter weiss at around 12:00,and sphincter injury caused by mirror body elevation,etc.Some precautions during the operation were as follows:(Ⅰ)reducing laser ablation;(Ⅱ)separation off the reserved side lobe mucosa before peeling;(Ⅲ)avoid 12:00 distal mucosal tear;(Ⅳ)using blasting holmium laser energy not lens body to peel glands,which can avoid sphincter injury by mirror body elevation force.Results: We identified 272 patients who underwent HoLEP.The median volume of enucleated adenomas was 92±24 g.The median IPSS before surgery was 23.3±6.1.Average(range)operation time was 86±21 minutes.Amount of bleeding was 56±14 mL.Postoperative patients of hospital stay was 32±5 h,average time of indwelling catheter time was 22±6 h.Patients were followed up for 6-28 months time,an average of 12.4 months.Postoperative patients with international prostate symptom score progressive declined.The quality of life score was 6.7±2.6.The maximum urinary flow rate also improved(P<0.05).Postoperative complication included urge urinary incontinence(36 cases,13.2%),31 of which did not occur in the first 5 days,2 of which lasted for 2 days.However,there was no real urinary incontinence case.Conclusions: By improving HoLEP technology and treating the incontinence reason predictably,HoLEP proved to be a safe and effective therapy,with fewer surgical complications,and it may be potential to become a new gold standard for treating BPH.
