Stenting

A stent is a tiny mesh tube that is inserted into a vessel to reshape the vessel walls. They are often inserted into blood vessels that have been narrowed by plaque buildup (atherosclerosis) or due to collapse. Angioplasty is often performed to widen the blood vessel, then a stent is placed inside the blood vessel to prevent the blood vessel from collapsing or narrowing again. Stents are also placed as stent grafts to create new vessel walls in the case of abdominal aortic aneurysm (AAA).

Stent placement is a catheter-based procedure. The catheter carries the stent to the location of the narrowed or collapsed blood vessel, then the stent is placed in position, possibly as part of the balloon angioplasty procedure.

Ureteral Stenting

The ureters are narrow tubes that carry urine from the kidneys to the bladder. This tube may become blocked or damaged, preventing urine from flowing freely. Blockage may be caused by kidney stones, cancer, blood clots, or infection.

A ureteral stent is a tube that is placed in the ureter to allow urine to flow from the kidney to the bladder. It is generally left in place until the ureter has healed or the reason for the blockage has been treated.

Ureteral stents are usually inserted through the urethra and threaded up to the ureter. If this insertion method fails, it can be inserted through the skin in a needle-based procedure similar to nephrostomy catheter placement.

Ureteral stenting can be performed in our freestanding facility. The procedure takes about an hour and no overnight stay is required.
