A new video urodynamics to evaluate lower urinary tract function is presented. Video urodynamics was described originally as a combined radiographic and urodynamic monitoring. We describe certain modifications of original method, using the ultrasonotomographic method instead of the radiographic method. The urodynamic data and the simultaneous ultrasonotomography can be displayed through the display controller on the color display monitor. Our technique will be an extremely reliable method for the evaluation of lower urinary tract function.

We have previously reported a new method of video urodynamic examination combining urodynamic and ultrasonotomographic monitoring. A modified version of this combined urodynamic and ultrasonotomographic monitoring method is presented herein. Simultaneous ultrasonotomographic images and urodynamic data can be displayed in color on a color display monitor and videotaped with a video recorder, using a display controller, digital scan converter, and color encorder.
