A new in vitro method which enables the simultaneous recording of the electromyogram from various regions of the renal pelvis and the pressure changes associated with those electrical activities is described in an experiment on canine kidney. At the proximal end of the renal pelvis, the interval of the electromyogram was constant and pelvic pressure changes showed rhythmic activity, while the discharge interval of the proximal end was the same as the pressure interval. However, the discharge intervals of both the pelvic center and the pelviureteric junction were found to be multiples of that of the proximal end of the pelvis.
在一项对犬肾的实验中，描述了一种新的体外方法，该方法能够同时记录肾盂各个区域的肌电图以及与这些电活动相关的压力变化。在肾盂近端，肌电图的间隔是恒定的，肾盂压力变化呈现节律性活动，而近端的放电间隔与压力间隔相同。然而，发现肾盂中部和肾盂输尿管连接处的放电间隔都是肾盂近端放电间隔的倍数。
