The ureter provides a way for urine to flow from the kidney to the bladder peristalsis in the ureter partially forces the urine flow, along with hydrostatic pressure ureteral diseases and a double j stent, which is commonly inserted in a ureteral stenosis or occlusion, disturb normal peristalsis ineffective or no peristalsis could make the contour of the ureter.

Although the lumen of the ureter is of normal calibre, the lack of peristalsis through this portion effectively obstructs the flow of urine the back-up of urine proximal to this aperistaltic segment causes dilation of the ureter and renal pelvis this condition is referred to as megaureter for obvious reasons. The only known function of the renal pelvis and ureter is to convey urine from the kidney to the urinary bladder this transport is achieved in two ways: 1 by peristaltic activity a urine portion is pushed ahead of a contractile wave, which almost completely obliterates the tubular lumen.
