If you have a ureteral stent, you can expect pain in your bladder, urethra, and kidney when you urinate. Why? The stent temporarily changes the way the bladder, ureter, and kidney work together.
- Normally: The ureter has a one-way valve as it enters the bladder. When the bladder squeezes to empty as you urinate, the valve keeps the urine from flowing back into the ureter and kidney.
- With a stent: The stent is a hollow tube that extends through your ureter and into the bladder, and temporarily keeps the one-way valve from closing. This means that when your bladder squeezes as you urinate, some of the urine flows back up the ureter and presses on the kidney. This causes pain while you urinate.
