描述了一种用于使用经尿道方法加热前列腺的施加器。该技术使用三个微波天线和一个温度测量传感器连接到气囊（Foley）型泌尿导管的外表面。每个微波天线还包括一个内置热敏电阻，以控制温度和平衡功率。球囊导管确保天线在前列腺尿道中的快速且可再现的定位。报告了组织等效体模中施源器周围的二维SAR和稳态温度分布。纵向温度分布测量原位在施加器尿道接口和测量正常犬前列腺的纵向和径向温度分布和讨论。该技术似乎能够在长达5 cm长的圆柱对称体积内将温度升高至42 ℃以上，并在施加器周围径向穿透0.5 cm。
An applicator for heating the prostate gland using a transurethral approach is described. This technique uses three microwave antennas and a thermometry sensor attached to the outer surface of a balloon (Foley) type urological catheter. Each microwave antenna also includes a built-in thermistor to control temperature and balance power. The balloon catheter assures rapid and reproducible localization of the antennas in the prostatic urethra. The two-dimensional SAR and steady-state temperature distributions surrounding the applicator in tissue equivalent phantom are reported. Longitudinal temperature distributions measured in situ at the applicator-urethral interface and the longitudinal and radial temperature distributions measured in normal canine prostate are presented and discussed. The technique appears to be capable of elevating temperature to greater than 42 degrees C in a cylindrically symmetrical volume up to 5 cm length and 0.5 cm radial penetration surrounding the applicator.
