The image shows a UROVISION Visiostar Standard Double-J stent. This is a medical device designed to hold open a narrowed or blocked passageway within the urinary tract, such as a ureter or urethra. The stent is a thin, flexible tube that is inserted into the body through a small incision. It is often used to treat conditions such as kidney stones, tumors, or strictures that can block the flow of urine. The stent is typically left in place for several weeks to months, and then removed when it is no longer needed.
