对单次和多次射频热疗治疗前列腺增生症后６个月、１年、２年、３年的疗效观察，并与对照组和其他治疗方法进行比较，用尿动力学膀胱排尿时最大逼尿肌压和最大尿流率之间的相互关系，按Ａｂｒａｍｓ－Ｇｒｉｆｉｔｈｓ图表进行分析，评价射频热疗在治疗前列腺增生症中的地位。结果发现，单次射频在解除前列腺增生引起的梗阻与对照组比较，无任何改善作用（Ｐ＞０．０５）。但多次射频（３～５次）与单次疗效比较，有明显差别（Ｐ＜０．０５），与单用保列治或α－受体阻滞药物的效果相似，但远不及ＴＵＲＰ和开放手术的疗效（Ｐ＜０．０１～０．０５）。
The efficacy of single and multiple radiofrequency ablation of benign prostatic hyperplasia at 6 months, 1 year, 2 years and 3 years was compared with that of the control group and other treatment methods. The correlation between urinary pressure and maximal uroflow rate was analyzed according to the Abrams-Grifiths chart to assess the role of radiofrequency thermotherapy in the treatment of benign prostatic hyperplasia. The results showed that a single RF in the treatment of BPH-induced obstruction compared with the control group, without any improvement (P> 0.05). However, there were significant differences (P <0.05) between multiple radiofrequency (3 to 5 times) and single effects (P <0.05), which were similar to those of the single Prostate or α-blocker drugs, but far less than those of TURP and The effect of open surgery (P <0.01 ~ 0.05).
