This study compared the efficacy of 70- and 120-w 2-μm thulium：YAG VapoEnucleation of the prostate （ThuVEP） for patients with benign prostatic obstruction （BPO）. A prospective analysis of 84 patients with symptomatic BPO and prostatic enlargement （t〉 60 ml） who underwent either 70-w （n=44） or 120-w ThuVEP （n=40） non-randomly was carried out. Patient demographics and perioperative and 12-month follow-up data were analysed. The mean prostate volume was 79.90---27.49 ml in patients who had received 70-w ThuVEP, which was less than in those who had received 120-w ThuVEP （88.53＋-25.10; P=0.033）. The mean enucleation （resected weight/laser time, 2.16±1.21 g min-1 vs. 1.23±0.60 g min-1; P=-0.013）, operation efficiency （resected weight/total operation time, 0.76±0.35 g min-1 vs. 0.42＋-0.27 g min-1; P=-0.000） and percentage of resected tissue （66.93%±22.79% vs. 45.41%±23.33%; P=-0.000） were higher with 120-w treatment compared to 70-w ThuVEP. One patient （1.2% of total patients）（in the 120-w group） required a blood transfusion postoperatively. Sixty-one patients （73%） were available for review at the 12-month follow-up time point. The quality of life （QoL）, International Prostate Symptom Score （IPSS）, maximum urinary flow rate （Qmax）, postvoiding residual urine （PVR） and prostate volume improved significantly after treatment （P≤ 0.035） and were not significantly different between those treated with the different devices （70- and 120-w）. The median prostate volume reduction was 81.70% and 82.19% with 70- and 120-w ThuVEP, respectively. The incidence of complications was low and did not differ between groups treated with the different devices. Two patients （2.4%）（one per group） had a bladder neck contracture at the follow-up. ThuVEP is a safe and efficacious procedure for the treatment of symptomatic BPO. The incidence of complications was low with both devices. The 120-w thulium：YAG device enhances the effectiveness of Th,VEP with reeard to the oercentaee of resected tissue
