What is a ureteral stent?

A ureteral stent is a small tube placed in the urinary tube after a kidney stone has passed to reduce swelling.

Ureteral stent placement is a surgery to place a soft flexible plastic tube called a stent in the ureter. The ureters are long tubes that allow urine to pass from the kidneys to the bladder. A ureteral stent keeps the ureter open if it is narrowed or blocked. It can also be used to continue urine flow if the ureter is damaged while a damaged ureter heals.

A ureteral stent is a device employed in the ureter that's used largely to unobstruct kidneys.

A ureteral stent is a tiny, hollow tube that runs from the kidney to the bladder and stays in place for several weeks after a kidney stone procedure. A stent helps you in three important ways:

  • It holds your ureter open. Your ureter has some normal swelling after a kidney stone procedure. The stent keeps this swelling from blocking the ureter.
  • It prevents severe pain after a procedure. If your ureter is swollen shut, you can have severe stone-like pain for three to seven days. With a stent, urine flows freely and you don't experience this pain.
  • It can widen the ureter so small stone fragments pass more easily. A stent also causes its own temporary difficulties—ask your doctor what to expect.
