The ureter is a muscular tube extending from the kidney to the bladder, explains KidneyChat.com. As such, it transports urine from the kidney to the bladder. If one or both ureters are blocked they prevent urine flow. Blockages within the urinary tract affecting urine flow are dangerous and can cause damage to and infection in the kidneys, and any blockages should be relieved to avoid dangerous complications.

Blockages of the ureter may be caused by kidney stones or narrowing of the ureter, states KidneyChat.com. An operation on the ureter may cause a temporary blockage, and disease may also be the reason for an obstruction.

Kidney stents are structured to stay within the urinary system, says KidneyChat.com. One end of the stent is coiled within the kidney and the other end is coiled within the bladder to prevent displacement in case of any physical activity. With their flexible design, kidney stents can withstand various movements of the body. They have different lengths, but most stents for adults fall within the 9.5 to 12 inch range.
