Abstract

Attempts have been successful to obtain electromyographic (EMG) recording of discharges of action potentials at the proximal end of canine renal pelvis in vivo by application of the Gil-Vernet procedure of extended pyelolithotomy. The discharges recorded in vivo from the proximal end of the renal pelvis in adult mongrel dogs showed EMG patterns characterized by a slow-rising positive waveform with virtually constant discharge intervals, irrespective of micturitional condition: normosthenuric or diuretic. The EMG pattern had striking resemblance to that obtained for the pacemaker of pyeloureteral peristalsis at the pelvicalyceal border in vitro. Potentials recorded at the lower pelvis, pyeloureteral junction and ureter in vivo showed increased frequencies of discharge during diuresis, compared to normal condition, the discharge intervals being always integral multiples of the interval of potentials at the proximal end of the renal pelvis.

摘要

通过应用改良肾盂切开取石术的吉尔 - 韦尔内特（Gil-Vernet）方法，已成功尝试在犬类肾盂近端体内记录动作电位放电的肌电图（EMG）。在成年杂种犬肾盂近端体内记录到的放电显示出肌电图模式，其特征为正波形缓慢上升，放电间隔几乎恒定，与排尿状态无关：正常尿浓缩或利尿状态。该肌电图模式与在体外肾盂输尿管蠕动起搏器在肾盂肾盏边界处获得的模式极为相似。与正常情况相比，在体内下肾盂、肾盂输尿管连接处和输尿管记录到的电位在利尿期间放电频率增加，放电间隔始终是肾盂近端电位间隔的整数倍。
