In the multicalyceal kidney of the pig renal pelvic pressure waves were investigated in 15 units. The pelvis was perfused with bodywarm saline gradually increased from 0-20 ml/min. The study showed a predominantly unimodal activity but all systems showed periods of instability which were characterized by coupled pressure waves, high frequencies and cascade emptying. The amplitude of the pressure waves increased with increasing flow and the study showed correlation between low amplitude and high frequency and vice versa.
在猪的多肾盂肾脏中，对15个单位的肾盂压力波进行了研究。用体温生理盐水以0至20毫升/分钟的速度逐渐灌注肾盂。研究显示主要为单峰活动，但所有系统都显示出不稳定期，其特征为耦合压力波、高频和级联排空。压力波的幅度随流量增加而增大，研究表明低幅度与高频之间存在相关性，反之亦然。
