Abstract
Temporal and distributive properties of ureteral peristaltic contractions in the anesthetized pig were examined. Interperistaltic time intervals were recorded and their frequency during different urine flow rates was compared. Ureteral peristalsis was increased at high urine flow rates to a maximum of approximately 0.06 Hz. From the interperistaltic histograms, ureteral contractions were not clustered into a discreet multimodal spectrum. This represents the 1st evidence that the multicalyceal kidney had a system of pacemakers of differing fundamental frequencies, tending toward synchronism as urine flow increases.
