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.
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.
- 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.
What is renin?
Renin is an enzyme produced by the kidneys that helps control blood pressure. Renin works by activating other chemicals to narrow (constrict) blood vessels, which increases blood pressure; a decrease in renin levels helps lower blood pressure.
Normally, this mechanism keeps blood pressure within a healthy range. But some people develop chronic high blood pressure (hypertension). When this occurs, medicines may be used that block the action of renin on blood vessels.
