PATHOLOGY

Detailed explanation-1: -Each ureter is a small tube, about 25 cm long, that carries urine from the renal pelvis to the urinary bladder.

Detailed explanation-2: -These contractions occur in your digestive tract. Peristalsis is also seen in the tubes that connect the kidneys to the bladder. Peristalsis is an automatic and important process.

Detailed explanation-3: -2.5 Upper urinary tract physiology. Under normal circumstances, the peristaltic waves ensure the propulsion of the urinary bolus toward the bladder. As the urine is collected in the renal pelvis, the pelvic pressure increases and initiates a peristaltic contraction that is propagated along the ureter to the bladder.
