上尿路输送尿液功能的临床尿动力学研究

Urodynamic study of urine transport of the upper urinary tract

采用恒压肾盂灌注（ＣＰＰ）试验和恒压灌注肾盂造影对２６例成人上尿路输送尿液功能进行研究，发现上尿路输送尿液的方式和效率取决于需转运的尿量；ＣＰＰ试验不仅能定量测定上尿路的通畅性，也能定量测定其泵功能和膀胱充盈对上尿路动力学影响。认为ＣＰＰ试验将为上尿路输送功能和尿动力学的深入研究提供一种较好的方法。

The function of urine transport by the upper urinary tract depends on both the tube function and the pump function of the upper urinary tract, and is also affected by vesical compliance. Clinically emphasis was mainly focussed on the tube function when a dilated upper urinary tract was evaluated. The pump function of the upper urinary tract was not well known because of lack of tests or techniques to measure it. Presently transport function was evaluated in 26 adult patients by constant pressure perfusion (CPP) test and constant pressure perfusion pyelography. It was found that the pattern and the efficiency of urine transport by the upper urinary tract depended on the urine volume to be managed, and that CPP test measured well not only the tube function but also the pump function and the effect of vesical filling on upper urinary tract urodynamics. It is believed that CPP test might become a very useful means for the study of urodynamics and urine transport of the upper urinary tract.
