    • A method and apparatus for diagnostic evaluation of the urinary tract. The method comprises the steps of generating a urethral pressure profile and simultaneously monitoring and recording electrical signals derived from the urinary tract thereby generating an electrical or electromyographic profile. As fluid is inputted into the urethra the catheter is mechanically withdrawn therefrom at a constant velocity. Fluid pressure within the urethra is derived and recorded thereby providing a urethral pressure profile. Simultaneously, urethral electrical signals derived from one or more electrodes mounted on the catheter are amplified and graphically displayed, thereby plotting urethral electrical activity and urethral fluid pressure at given points along the urethra. The apparatus comprises an interface unit for withdrawing the catheter and for enabling measurement of the various diagnostic parameters.
    • 用于尿路诊断评估的方法和装置。 该方法包括产生尿道压力分布并同时监测和记录从尿道导出的电信号,从而产生电或肌电图。 当流体输入尿道时,导管以恒定的速度机械地从其中抽出。 导出和记录尿道内的流体压力,从而提供尿道压力分布。 同时,从安装在导管上的一个或多个电极获得的尿道电信号被放大并图形显示,从而在沿着尿道的给定点绘制尿道电活动和尿道液体压力。 该装置包括用于取出导管并用于测量各种诊断参数的接口单元。
