An analysis of 393 cases with benign prostatic hyperplasia treated with radio-frequency therapy

目的:试图了解射频(短波)治疗良性前列腺增生症的效果,并探讨其治疗机制。方法:将两个直径18cm 电极置于耻骨联合和骶尾部,功率密度1.16～2.00W/cm^2,并对部分病例进行治疗前后的B超检查。结果:治疗后总有效率90.1%,显效50.4%,有效39.7%,无效9.9%。结论:该法对刺激性症状的疗效优于梗阻性症状。治疗机制可能是消炎和缓解平滑肌张力,调解逼尿肌和尿道括约肌的功能。

Objective:This article attempts to understand the therapeutic effect of radio-frequency on benign prostatic hyperplasia and its mechanism.Methods:The incidence of various symptoms of 393 cases with benign prostatic hyperplasia was first analysed by retrospective method.The radio-frequency therapy was applied on the conjunctive site of pubic and the sacrococcygeal area,the dose was 1.16～ 2.00W/cm^2,20min,once a day or every other day for 16 times averagely.Results:The total effective rate was 90.1%,the excellent 50.4%.Conclusion:It is suggested that the radio-frequency therapy has a better effect for irritative symptoms of prostatic hyperplasia.It may eliminate the urinary inflamma- tion,relieve the smooth muscular tension and regulate the detrusor urinae and sphincter urethrae func- tions.
