目的探讨一种安全、简便、疗效确切的良性前列腺增生症（Ｂｅｎｉｇｎｐｒｏｓｔａｔｅｈｙｐｅｒｐｌａｓｉａ，ＢＰＨ）非手术治疗方法。方法采用ＷＥ７５６６型前列腺组织内消融治疗仪及自行制作的消融针引导器，对２３例ＢＰＨ患者经直肠前列腺组织内针刺消融治疗（Ｔｒａｎｓｒｅｃｔａｌｉｎｔｅｒｓｔｉｔｉａｌａｂｌａｔｉｏｎ，ＴＲＩＡ）。据前列腺增生体积确定进针数，本组平均进９针，进针深度１５～２０ｃｍ，每针消融时间７ｍｉｎ，消融最高温度为９５℃。对２１例患者治疗后３个月、６个月分别进行了随访。结果残余尿、国际前列腺症状评分（Ｉ－ＰＳＳ）、生活质量评分（ＱＯＬ）分别与治疗前比较差异有极显著意义（Ｐ＜００１），最大尿流率（ＭＦＲ）及前列腺体积治疗后６个月改善显著（Ｐ＜００１）。结论为治疗良性前列腺增生症提供了一种新的方法 Objective To investigate a non-surgical treatment of benign prostatic hyperplasia (BPH) that is safe, simple and effective. Methods Twenty-three patients with BPH underwent transrectal intitial translational ablation (TRIA) with WE7566 prostate tissue ablation device and self-made ablation needle guider. According to the volume of benign prostatic hyperplasia to determine the number of needles, the average group into the 9-pin, needle depth 15 ~ 2  0cm, each needle ablation time 7min, ablation temperature was 95 ℃. Twenty-one patients were followed up for 3 months and 6 months respectively. Results Residual urine, I-PSS and QOL were significantly different from those before treatment (P <001), maximum flow rate (MFR) and volume of prostate after treatment 6 months improved significantly (P <0  01). Conclusions for the treatment of benign prostatic hyperplasia provides a new method
