- 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 3 to 7 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.

What is a ureteral stent?
Intermountain Healthcare answeredA 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:
What can cause urinary problems in men besides an enlarged prostate?
It was once thought that the urinary difficulties that men experience as they age were the result of an enlarging prostate constricting the urethra. If this were the case, symptoms would tend to get worse as the prostate got larger. But this is not the case. Rather, the smooth muscle in the prostate and the bladder also play key roles in causing urinary symptoms. When the smooth muscle gets chronically tense, it puts pressure on the urethra and bladder neck, increasing the resistance to urine flow. And, as resistance to urine flow increases, the bladder has to work harder to empty itself. To do this, the bladder contracts its muscular wall, called the detrusor muscle. This action causes the muscle to thicken and get stronger, further reducing the capacity of the bladder.
Sometimes the muscle contracts when the bladder is not full, giving the sensation of needing to urinate. Over time, as the bladder tries harder to empty itself, it becomes less efficient. The result: The need to urinate more frequently and the sensation of not having emptied the bladder of urine.
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.
