- 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.

Why does it hurt when I urinate with a ureteral stent?
Intermountain Healthcare answeredIf 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.
How is a ureteral stent removed?
Intermountain Healthcare answeredUreteral stents usually stay in for a few weeks, depending on the procedure you had. With some operations, the stent will stay in place for 6 weeks afterward. Your surgeon will give you the details. To remove most stents, a soft, flexible scope (about the size of a urine catheter) is sent up the urethra to the bladder. A grasper on the scope catches the stent and pulls it out through the urethra. The urologist will put numbing jelly inside the urethra before inserting the scope. You may feel some burning as the scope moves past certain parts of the urethra, but the procedure lasts just a few minutes. Pulling the stent feels a bit like pulling out a bladder catheter. Sometimes a short string is attached to the stent and hangs out of the urethra. In these cases, the stent is removed by pulling the string.
What is the urinary tract?
Jill Rabin, Obstetrics & Gynecology, answered
The urinary tract is the passageway through which bodily waste products are filtered and through which urine is produced, stored, and excreted. The upper urinary tract consists of the kidneys and the ureters that are attached to them. The bladder and the urethra are in the lower urinary tract.
We remain continent when the organs (kidneys, bladder, brain), tubes (ureters and the urethra), and muscles (sphincter muscles and the pelvic floor muscles), as well as the spinal cord, that comprise and control the urinary tract function properly. Continence is achieved when the entire urinary system works like a well-tuned motor: when there is normal lower urinary tract support and normal functioning of the sphincter muscles.
