Abstract：Objective:We evaluated the clinical efficacy and safety of 2 micron continuous-wave laser vaporesection in treating senile patients with obstructive benign prostatic hyperplasia (BPH). Methods:106 senile patients with BPH were enrolled, whose age are all more than 70 years old. All the patients with obstructive BPH received analyzed using a 70 W 2-micron continuous-wave laser between July 2010 and July 2012. The mean (range) age of the patients was (82.8±9.6) (70-89) years. Resection time, bladder irrigation time and catheter time were measured perioperatively and the following variables were assessed before and 24 hours after vaporesection: bleeding volume and electrolyte changes and the safety perioperatively. IPSS、OABSS and QOL of all the patients were recorded before and 3 months after operation. Results:The mean resection time was (69.0±12.4)(32-128) minutes. The time of bladder irrigation is (-23.0±5.1) (8-28)h. The mean catheter time was (3.6±0.7) (3-5) days. Before and after operation the patients with electrolyte disturbance and bleeding volume change was not observed (P>0.05). No severe cardiovascular、cerebral and pulmonary complications occurred during perioperative period. all the index including IPSS、OABSS、QOL were obviously improved (P＜0.05) after treatment 3 months later. Conclusions:2 micron continuous-wave laser of treatment senile patients with BPH has great advantages by safty of peroperative period decreasingresection time, bladder irrigation time and catheter time and the obvious clinical efficacy.
