The pressure-flow relationship of the normal pyeloureter was investigated in 10 pigs. From a mean baseline pressure in the pelvis of 7.5 cm H2O, the pressure increased during perfusion. The pressure increase from baseline to 8 ml/min was significant. It was noticeable that a perfusion rate of 8 ml/min resulted in intrapelvic pressures of more than 27 cm H2O in 4 of the 10 pigs. A further increase in perfusion rate gave only a slight, additional increase in pressure with linear relationship between flow rate and pressure. The steep rise in pressure from baseline values of 8 ml/min and the slight additional increase in pressure hereafter was probably caused by a transformation of peristalsis to a continuous flow.
对10头猪的正常肾盂输尿管压力-流量关系进行了研究。肾盂平均基线压力为7.5 cm H₂O，灌注期间压力升高。从基线到8 ml/min时压力升高显著。值得注意的是，在10头猪中有4头，灌注速率为8 ml/min时肾盂内压力超过27 cm H₂O。灌注速率进一步增加时，压力仅略有额外升高，流量与压力呈线性关系。从基线值到8 ml/min时压力急剧上升，此后压力略有额外升高，这可能是由于蠕动转变为持续流动所致。
