A method of synchronous study for monitoring the pressure activity of the rectum, bladder and urethral sphincter was described. Intrarectal pressures were obtained using a 8 F custom made balloon catheter. Constant urethral infusion with intrasphincteric pressure recording was arranged through a specially designed 12 F trilumen catheter. Simultaneous intravesical infusion and independent bladder pressure recording were conducted through two other channels of this catheter. This radiologic-aided study was used for functional evaluation of the bladder and its outlet. The physical factors, such as urethral infusion flow-rate, and the compliance of the infusion catheter hydraulic system governing the interpretation of the study during voiding and nonvoiding states, were described. With an experience of 145 studies on spinal cord injury patients and normal subjects, this method has been found to be a useful clinical urodynamic technique well suited even to a nonambulatory spinal cord injury patient.
描述了一种同步研究方法，用于监测直肠、膀胱和尿道括约肌的压力活动。使用定制的8F气囊导管获取直肠内压力。通过专门设计的12F三腔导管进行持续尿道灌注并记录括约肌内压力。通过该导管的另外两个通道进行同步膀胱内灌注和独立膀胱压力记录。这项放射学辅助研究用于膀胱及其出口的功能评估。描述了诸如尿道灌注流速等物理因素，以及在排尿和非排尿状态下控制该研究解读的灌注导管液压系统的顺应性。通过对脊髓损伤患者和正常受试者进行145项研究的经验发现，该方法是一种有用的临床尿动力学技术，甚至适用于非卧床脊髓损伤患者。
