An Overview of Ureteral Stent

Ureteral stents are often used in urology for obstruction and stenosis caused by various reasons. The ureteral stent tube is often called "double J tube" because its two ends curl like the English word "J". It is also called "pig tail tube" because its two ends look like pigtails. As shown in the above figure, the ureteral stent is generally placed at one end in the kidney, the other end in the bladder, and the middle passes through the ureter.

Purpose of ureteral stent

Urine is transported from the kidneys to the urinary bladder by the ureters. In exceptional situations, both ureters may become obstructed.

A ureteral stent is inserted into the ureter to restore urine flow to the bladder. In patients with confirmed kidney infections or diseased bladders, ureteral stents can also be used.

Alternatively, ureteral stents can be used after or during urinary tract surgical treatments to create a mold around which healing can occur, and to divert urinary flow from areas of leakage.

It can also be used to control kidney stones or avert stone migration just before treatment, and to make the ureters more visible during complicated surgical procedures.

Depending on the circumstances, the stent may be left in place for a short period or for an extended time.
