The effects of adrenaline and noradrenaline and of α- and β-receptor blocking agents on electrical and mechanical activity of the pyeloureteral system were investigated in unanaesthetized dogs and guinea-pigs and in isolated preparations of dogs, r

1. The normal ureteral peristalsis of the guinea-pig was determined by long-term recordings of electrical activity in the unanaesthetized animal. The frequency distribution of peristaltic period durations is multimodal. The normal basic frequency is

To determine the precise localization of the pacemaker in the renal pelvis of the unicalyceal rabbit kidney, the spontaneous activity of muscle strip preparations was investigated in vitro. (1) The highest frequency of spontaneous contractions was fo

The renal pelvis and the ureter represent a functional system with myogenic excitation generation and conduction. The activity of this system is modulated by the autonomic nervous system: alpha-adrenergic and cholinergic substances stimulate, beta-ad

Ureteral peristalsis was measured in unanaesthetized dogs and in isolated preparations of dogs and rats. The normal pacemaker is localized — as in the guinea-pig — in the proximal parts of the renal pelvis. The frequency distribution of peristalt

Ureteral peristalsis originates in the most proximal parts of the caliceal system. It is then conducted to the ureter by way of myogenic excitation conduction. In the pyeloureteral region, however, there seems to be some sort of physiological blockad

In isolated muscle strips of porcine renal pelvis and ureter, the calcium antagonist nifedipine (3.10(-7) moles/l) completely suppressed spontaneous phasic mechanical activity and the phasic components of an adrenaline-induced activation (P-component
