THE PERISTALTIC MOVEMENT OF THE URETER

THE IN VIVO DYNAMIC GRADIENT OF THE URETERAL CONTRACTION

Abstract

Investigation of the peristaltic movement in twenty one healthy humans and eighteen mongrel dogs was undergone by means of the electric strain gauge manometer. The dynamic gradient of the amplitude, frequency and resting pressure versus various recording sites of the ureter were recorded in both humans and dogs. The relationship of the ureteral dynamic gradient to the rate of urine flow, travel rate of ureteral contraction and rhythmicity of the peristaltic waves were established and discussed, to clarify the physiology of the ureter.
