What is a Stent Graft?
A stent graft, alternatively referred to as a covered stent, is a specialized vascular stent designed to address certain medical conditions. It consists of a metal mesh support and a leak-proof polyester covering. While the stent graft is contained within the covering, it remains expandable similar to a bare-metal stent. The primary purpose of stent grafts is to strengthen weakened areas in the arteries. The presence of a fabric covering enables the stent graft to form a tight seal with the surrounding blood vessel, ensuring optimal functionality.
What is a Ureteral Stent?
A ureteral stent is a medical device used to keep the ureters, the tubes that transport urine from the kidneys to the bladder, unobstructed. It plays a crucial role in preventing kidney damage and maintaining proper urinary function. In certain cases, a ureteral stent is used as a temporary solution while waiting for a more permanent procedure.
Unlike other types of stents, ureteral stents are typically longer to match the length of the affected ureter. This ensures that the entire pathway remains open and free from any blockages.
In recent years, there has been an increase in the popularity of ureteral stents that incorporate coatings to reduce the risk of infections. These innovative stents provide an added layer of protection and contribute to better patient outcomes.
