A New Video Urodynamic System for Simultaneous Display of Ultrasound Images and Urodynamic Data

视频尿动力学显示同步尿动力学数据与下尿路图像提供了更精确的信息下尿路功能。这种方法最初被描述为一种结合放射学和尿动力学监测。我们描述了原始方法的某些修改，使用超声方法代替放射学方法作为成像方式。膀胱和尿道的超声研究采用经直肠线性扫描或经腹扇形扫描。尿动力学检查采用多导生理记录仪（Nihon-Kohden，RM-6000），可同时记录膀胱压力、直肠压力、逼尿肌压力、尿流率和外括约肌肌电图，所有尿动力学数据通过多导生理记录仪和显示控制器（Nihon-Koden，VY-600 G）彩色投影在彩色显示器（Nihon-Koden，VD-610 G）上。显示控制器使得在先前方法中观看尿动力学数据所必需的电视摄像机成为不必要的，并且尿动力学数据以彩色显示。超声图像通过数字扫描转换器（Edic，艾德-1280 A）和显示控制器投射，并叠加在彩色显示监视器上的扫描尿动力学数据上，我们的视频尿动力学系统被认为具有某些独特的优点，因为这个过程可以很容易地在不使用电视摄像机的情况下进行。

Video urodynamics displaying simultaneous urodynamic data with images of lower urinary tract gives more precise information about lower urinary tract function. This method was described originally as a combined radiographic and urodynamic monitoring.We describe certain modifications of original method, using ultrasound method instead of the radiographic method as an imaging modality. Ultrasound study of the bladder and urethra was performed using transrectal linear scanning or transabdominal sector scanning. Urodynamic examination was performed on a polygraph system ( Nihon-Kohden, RM-6000 ), capable of simultaneously recording bladder pressure, rectal pressure, detrusor pressure, urine flow rate and external sphincter EMG.All urodynamic data were projected in color on the color display monitor ( Nihon-Koden, VD-610G ) through the polygraph system and the display controller ( Nihon-Koden, VY-600G ). The display controller makes the television camera, which was mandatory for viewing the urodynamic data in the previous method, unnecessary and urodynamic data are shown in color. The ultrasound images are projected via the digital scan converter ( Edic, ED-1280A ) and the display controller, and are superimposed over the sweeping urodynamic data on the color display monitor.Our video urodynamic system is considered to have certain distinct advanteges in that this procedure can be easily performed without using the television camera.
