Experiments were performed in vitro to explore the influence of isoproterenol on the canine pelvi-ureteral system. The rhythmic changes of intrapelvic pressure became no longer manifest and simultaneously recorded electromyograms revealed disappearance of peristalsis at sites distal to the upper region of renal pelvis following application of isoproterenol, while the pacemaker at the pelvi-calyceal border continued to discharge with an enhanced pace. This result has demonstrated that the renal pelvic pressure recorded during treatment with isoproterenol did not reflect the pacemaker activity of the renal pelvis.
进行了体外实验以探究异丙肾上腺素对犬肾盂输尿管系统的影响。肾盂内压力的节律性变化不再明显，同时记录的肌电图显示，应用异丙肾上腺素后肾盂上部远端部位的蠕动消失，而肾盂肾盏交界处的起搏器继续以加快的频率放电。这一结果表明，异丙肾上腺素治疗期间记录的肾盂压力并未反映肾盂的起搏器活动。
