Abstract: Ojbective: To compare the therapeutic effects of the 2μm continuous wave laser vaporesection of prostate and transurethral electrovaporization resection of prostate（TUVP） for the treatments of symtomatic benign prostatic hyperplasia（BPH）.Methods: 153 cases of BPH were treated with 2μm continuous wave laser vaporesection and TUVP.All patients were followed up.Results: international prostatic symptom score（IPSS）,quality of life（QOL） and（Qmax） were significantly improved after both of the procedures and therapeutic results（P＜0.05）;no significant difference in the improvement of subjective symptoms and Ojbective signs had been noted with the different procedured（P＞0.05）.Mean operative time was（37.2±15.4）min for TUVP and（44.1±26.8）min for 2μm group,The resection time was longer for 2μm group than TUVP（P＞0.05）,but the interoperative bleeding and catheterization time were less in 2μm group than TUVP（P＜0.05）.Postoperative complications were less in 2μm group than TUVP（P＜0.05）.The incideased of heamatouria in TUVP group had been 41.4%.Conclusions: 2μm continuous wave laser vaporesection has the same therapeutic effect as TUVP and less adverse side effects than TUVP;it is a newly technology for the treatment symptomatic BPH.
