ABSTRACT:
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 As fluid is inputted into the urethra the catheter is mechanically withdrawn therefrom at a constant velocity.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.
