Kidney Stent: The kidney is one of a pair of vertebrate organs situated in the body cavity near the spinal column that excretes waste products. In humans, they are bean-shaped organs about 4¹/₂ inches long lying behind the peritoneum in a mass of fatty tissue.
Doctors place stents in arteries as part of a procedure called percutaneous coronary intervention (PCI), also known as coronary angioplasty. With Kidney stent, Dr. De will make a small opening in a blood vessel. Through this opening, he will thread a thin, flexible tube called a catheter. The catheter will have a deflated balloon at its tip.
Ureteral stents are small tubes inserted into the ureter to treat or prevent a blockage that prevents the flow of urine from the kidney to the bladder. The most common reason for ureteral stents is the treatment of kidney stones
Dr. De will use special dye to help show narrow or blocked areas in the artery. He or she will then move the catheter to the area and inflate the balloon.
As the balloon inflates, it pushes the plaque against the artery wall. This widens the artery and helps restore blood flow. The fully extended balloon also expands the stent, pushing it into place in the artery.
The balloon is deflated and pulled out along with the catheter. The stent remains in your artery. Over time, cells in your artery grow to cover the mesh of the stent. They create an inner layer that looks like the inside of a normal blood vessel.
In the majority of patients, the stents are required for only a short duration, from a few weeks to a few months. However, a stent in the right position can stay in for up to three months without the need to replace it. When the underlying problem is not a kidney stone, the stent can stay even longer.
