经尿道微波针组织间消融术治疗前列腺增生症

Transurethral microwave needle interstitial ablation for the treatment of BPH

１９９４年１１月～１９９５年９月采用经尿道微波针组织间消融术（ＴＵＷＮＡ）治疗前列腺增生症（ＢＰＨ）患者２５例，其中２１例随访６个月。术后前列腺症状积分下降了１６．８±４．１分（８０．１％），最大尿流率增加了６．７±１．９ｍｌ／ｓ（７４．４％），剩余尿减少了６６．７±３７．２ｍｌ（７６．１％），前列腺体积减少了１．１±１．７ｍｌ（２．３％），其差异有显著性意义。病理检查见增生的前列腺组织发生凝固坏死，有的形成空腔，造成前列腺实质缺损，有效地解除了后尿道梗阻，是一种可望代替手术的ＢＰＨ治疗方法。

From Nov. 1994 to Sep. 1996, transurethral microwave needle interstitial ablation(TUWNA) was conducted for 25 patients with BPH, 21 patients have been followed up for 6 months. One month after the treatment,AUASS decreased form 20.6±6.3 to 4. 1 ±2.3(80.0%), P<0.00l;RU decreased from 87.7±44.9 to 21.0± 12.7ml(76.0%),P<0.001;VP deceased from 45.9± 13.5 to 44.8± 12.6ml(2.3%),P<0.05. Obvious improvements, both subjectively and objectively, were observed after TUWNA, The long term effect, however, needs further evaluation.
