...M. Graw; H. Engelhardt Occlusive ureteral peristalsis is simulated in an enlarged technical model of the ureter with a lobe-shaped lumen. The local pressure pulse is measured with catheters of different caliber and the influence of the catheters size and position on the uromanometrogram (UMG...

...Takashi Morita; Takashi Suzuki An electromyographic study of the responses of the pelvicalyceal border which is the pacemaker region of ureteral peristalsis, and of the renal pelvis and ureter to dobutamine and terbutaline, Β 1 - and Β 2 -adrenergic stimulants, respectively, was performed using...

.... The following concept for the generation of ureteral peristalsis in multicalyceal kidneys is developed: several (primary) oscillators exist in the calyces; in the pyeloureteral junction a (secondary) pacemaker exists which has an intrinsic frequency similar to that of the calyceal pacemakers; both processes...

... is limited by the lowest detected mode in the interperistaltic interval distribution and is accompanied with a reduction in the speed of transmission and ureteral dilation. Comparative data on the symmetry of urine flow between the two kidneys and ureteral peristalsis at constant and transient diuresis...

...C.E. Constantinou; J.R. Hrynczuk The influence of Pentothal anesthesia in blocking the mechanism initiating ureteral peristalsis in the dog is examined. Pressure measurements of pacemaker rhythmicity were made through renal cortical catheterization of the renal pelvis. Simultaneously, ureteral...

...C.E. Constantinou The patterns of mechanical contractility in the pyeloureteral pacemaker system were explored in an effort to identify some of the properties of initiating ureteral peristalsis. Rabbit renal pelvises were studied in vivo , in vitro perfused with Krebs solution through the renal...
