Used for Several Reasons

Stints are an artificial tube that is placed inside passages in the body that allow for the free movement of body fluids. The purpose of the stint is to hold the passage way open and prevent it from closing due to collapse, kinking, or disease processes. Stints are used for a variety of diverse medical purposes. The first purpose of the stint is to prop open arteries in the heart that have been unclogged during angioplasty. These stints are called coronary artery stints and may be made of metal mesh, have medication releasing features, or be covered with a biocompatible material. This procedure is frequently performed after heart attacks or cardiac stress testing reveals obstruction of coronary arteries due to coronary artery disease. Vascular stints can usually be placed by accessing an artery in the groin and threading the stint through the blood vessel, up to the blockage. This procedure is much simpler and avoids coronary bypass surgery in a great number of cases. The next type of stint that is frequently used are urological stints. Stints may be placed in the renal arteries during angiography to help restore blood flow to a kidney that has been failing because of the decreased blood supply. Another type of urological stint is a urethral stint, the purpose of which is to maintain the potency of the ureter. The ureters are the passageways for urine to pass from each kidney to the bladder. Urethral stints prevent the ureters from become blocked due to kinks, tumors, or kidney stones. Another type of urological stint is the urethral stint (not to be confused with urethral stint), this type of stint is used to hold open the urethra, which is the opening that goes from the bladder to the outside of the body. This opening can become obstructed by tumors, prostate enlargement, or strictures. The third type of stint is called a peripheral stint and is used to restore blood flow to the arteries of the arms and legs much the same way that coronary artery stints restore blood flow to the heart. The peripheral stint corrects abnormalities in the blood vessels due to blockages from disease process or stricture. Another use for stints is for stint grafting. Stint grafting is used in procedures involving the blood vessels, most commonly the repair of abdominal aortic aneurysms. The stints used for this type of procedure commonly have a fabric covering over the metal mesh. The purpose of this stint is to provide a pathway to divert blood away from and around the aneurysm instead of into the aneurysm sack itself. These are some of the most common uses for medical stints, but are by no means the only utilizations for these devices. Other applications include esophageal stints to treat constrictions of the esophagus, biliary stints to reopen blocked bile ducts, pancreatic stints, and rectal stints. The use of the stint has reduced and prevented the need for more invasive procedures. Thus the patient, the hospital, and the insurance company are saved money, recovery time, and lengthy hospital stays. For more information on medical stints.nurtition health tips world
