This study is intended to elucidate the process of urinary transport through the pelvi-calyceal system (PCS). PCS-motility of a total of 28 PCS was qualitatively and quantitatively determined in 9 stone patients and 14 control persons by examination of contrast medium excretion. From X-ray videograms recorded by means of Siemens urography, four different urinary transport types could be distinguished as well as the duration of the contraction periods and the intervals between the PCS-contractions. In stone patients physiological types of urinary transport are less common (33%) than in control subjects (81.25%). In stone patients the PCS is often characterized by reduced or even absent motility. Calyceal reflux is usually found in the systolic phase of PCS-contractions, which may apparently be regarded as a physiological process.
本研究旨在阐明尿液通过肾盂肾盏系统（PCS）的运输过程。通过造影剂排泄检查，对9例结石患者和14例对照者的总共28个PCS的运动情况进行了定性和定量测定。从西门子尿路造影记录的X线摄像中，可以区分出四种不同的尿液运输类型以及收缩期的持续时间和PCS收缩之间的间隔。与对照者（81.25%）相比，结石患者中生理性尿液运输类型较少见（33%）。结石患者的PCS通常表现为运动减弱甚至缺乏。肾盏反流通常出现在PCS收缩的收缩期，这显然可被视为一个生理过程。
