Stretching of the renal calices by urine flowing from the collecting ducts initiates peristaltic contractions that spread to the renal pelvis and then downwards along the length of the ureters.
Stretching of the renal calices by urine flowing from the collecting ducts initiates peristaltic contractions that spread to the renal pelvis and then downwards along the length of the ureters.
Peristaltic contractions in the ureter are enhanced by sympathetic stimulation and inhibited by parasympathetic stimulation.
