The image shows a UROMED Heparius ureteral stent. This is a medical device designed to hold the ureters open to allow for the free flow of urine. The stent is a thin, flexible tube that is inserted into the ureter through a small incision. It is often used to treat conditions such as kidney stones or ureteral strictures. The stent is typically left in place for several weeks to months, and then removed when it is no longer needed.
