项目摘要

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.

视频尿动力学同时显示尿动力学数据和下尿路图像，为下尿路功能提供更精确的信息。该方法最初被描述为结合x线摄影和尿动力学监测。我们描述了对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直线扫描或经腹部扇形扫描。尿动力学检查在测谎仪系统（Nihon-Kohden, RM-6000）上进行，该系统能够同时记录膀胱压、直肠压、逼尿肌压、尿流量和外括约肌肌电图。所有尿动力学数据通过测谎系统和显示控制器（Nihon-Koden, VY-600G）以彩色投影在彩色显示监视器（Nihon-Koden, VD-610G）上。显示控制器使前一种方法中查看尿动力学数据时必须使用的电视摄像机将不必要的尿动力学数据显示为彩色。超声图像通过数字扫描转换器（Edic, ED-1280A）和显示控制器投影，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势，因为该过程可以很容易地进行，而无需使用电视摄像机。
