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 can cause kidney scarring?
Anthony Komaroff, MD, Internal Medicine, answeredScarring occurs during the healing process after damage to living tissue and cells. Scars are an imperfect process for damaged tissues to heal. Scarring usually does not cause pain. It can on rare occasions lead to impaired function of an organ if the scarring is extensive.
When this occurs in the kidney, it is usually the result of an infection within the kidney tissue. Very often, this occurs from a urinary tract infection. There would rarely be any related pain or other symptoms.
Scarring may be seen on imaging of the kidney (ultrasound, CAT scan, or MRI) without the person ever knowing they have scarring.
Another much less common cause of kidney scarring is a blood clot that prevents oxygen getting to a part of the kidney. This leads to damage of the tissue and the formation of scars.
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.
