After the procedure, urine may flow better from your kidneys to your bladder. A ureteral stent may be left in place for several days or for as long as several months. Your doctor will take it out when you no longer need it. Or, in some cases, it may be taken out at home.
If left in place for too long, a stent can become encrusted with a “crystal” (stone-like) coating on its surface. This does not normally cause problems although it may worsen some urinary side-effects (especially pain & bleeding).
They are made to be permanent — once a stent is placed, it's there to stay. In cases when a stented coronary artery does re-narrow, it usually happens within 1 to 6 months after placement.
The stent stays in the artery permanently to hold it open and improve blood flow to your heart. In some cases, more than one stent may be needed to open a blockage.
Ureteric stents are usually left in place for between a few days and three months, depending on why one has been inserted. When planning how long to leave the stent in place, the risk of the stent becoming blocked is considered, as they can become encrusted with the same deposits that form kidney stones.
Forgotten ureteral stents can cause a spectrum of complications ranging from hematuria, stent occlusion, migration, fragmentation, encrustation, and stone formation to serious complications like recurrent urinary tract infection (UTI), urinary tract obstruction, and renal failure [5], [6].
Results: Of the 104 individuals in the final cohort, 64% had symptoms after stent removal (pain, hematuria, frequency, urgency, or fever), and among those with symptoms, 60% experienced pain/discomfort.
As recommended in the National Disease Management Guidelines (6), patients with coronary heart disease and those who have undergone stent implantation should be followed up regularly (every three to six months) by their primary care physicians, independently of any additional visits that may be necessitated by ...
Symptoms like fatigue, chest pain or shortness of breath can indicate in-stent restenosis. If you experience symptoms, you should contact your healthcare provider. Newer, safer drug-eluting stents can lower your risk of developing in-stent restenosis.
Sometimes heart problems return after a stent procedure. If that happens, you usually have symptoms—like chest pain, fatigue, or shortness of breath. If you do have symptoms, a stress test can help your doctor see what's going on. It can show if a blockage has returned or if there's a new blockage.
One concern shared by many patients is if the stent will be able to move around in the arteries once it has been inserted. In short, the answer is no. Once a stent is opened in an artery, the tissue cells of the artery wall begin to grow over the stent. The stent becomes a part of the artery wall and cannot move.
There are two ways to remove ureteral stents. Commonly, the stent is removed by cystoscopy, an outpatient procedure which takes only a few minutes.
Introduction: Double J (DJ) stents are often removed under local anesthesia using a rigid cystoscope. Patients experience significant pain during this procedure and also continue to have discomfort during voiding for a few days.
The term "angioplasty" means using a balloon to stretch open a narrowed or blocked artery. However, most modern angioplasty procedures also involve inserting a short wire mesh tube, called a stent, into the artery during the procedure. The stent is left in place permanently to allow blood to flow more freely.

Restenosis occurs when an artery that was opened with a stent or angioplasty becomes narrowed again. Atherosclerosis is the buildup of fatty deposits and cholesterol inside of your arteries. This buildup can limit the blood supply to your heart.
The necessity of keeping a heart stent is only to the fluidity of the blood inside the arteries. But once the surgery conducted then it is mandatory to remove the stent and replace it with the new one.
A stent can cause blood clotting, which may increase the risk of heart attack or stroke. The National Heart, Lung, and Blood Institute state that about 1 to 2 percent of people who have stented arteries develop a blood clot at the site of the stent. Doctors will usually prescribe one or more drugs to prevent clotting.
Following a stent procedure, you take medications to prevent blood clots that could lead to restenosis, or renarrowing of the artery. To prevent this problem, doctors may use a stent coated with medication. Aspirin must be taken indefinitely, no matter what type of stent is used.
Will I feel the stent? No. You will not feel the stent inside of you. (Though you will probably feel better after it has been implanted and blood flow in your coronary artery has been restored.)
You will need to take antiplatelet medicines, or blood thinners, to prevent blood clots from forming in the stents in your arteries. Your provider may prescribe these medicines for 1 year or more after getting a coronary stent. For carotid or peripheral artery stents, it may be 1 month or more.
Examples include aspirin, clopidogrel (Plavix), prasugrel (Effient), and ticagrelor (Brilinta). It is critical that these medicines not be stopped without checking with your cardiologist, for stopping them prematurely can result in another heart attack from the stent closing off abruptly.
One can go back to their normal routine within 2 to 3 days after undergoing the procedure, depending on the doctors' recommendations. However, patients who undergo this procedure must ensure they follow the above-mentioned lifestyle changes to lead a long and healthy life after stent placement.
Stent Removal
Most patients stay awake when a stent is removed, but you may have a numbing gel applied to your urethra (your urinary tract opening) before the procedure. If your stent has a string attached, your doctor gently pulls on it to remove the stent.
Stenting is a minimally invasive procedure, meaning it is not considered major surgery. Stents can be made of metal mesh, fabric, silicone, or combinations of materials. Stents used for coronary arteries are made of metal mesh. Fabric stents, also called stent grafts, are used in larger arteries such as the aorta.
Recovery from angioplasty and stenting is typically brief. Discharge from the hospital is usually 12 to 24 hours after the catheter is removed. Many patients are able to return to work within a few days to a week after a procedure.
