Ureteral stent set refers to a collection of medical devices and instruments specifically designed for the insertion and placement of a ureteral stent. A ureteral stent is a hollow tube inserted into the ureter, the tube connecting the kidney to the bladder, to help restore or maintain the flow of urine.
Here are some common components that may be included in a ureteral stent set:
Ureteral Stent: The set will typically include the ureteral stent itself, which is a thin, flexible tube usually made of silicone or polyurethane. The stent has a hollow lumen and may have a curl on each end to prevent migration.
Guidewire: A guidewire is a thin wire used to facilitate the placement of the ureteral stent. It is inserted through a cystoscope or ureteroscope and guided up into the ureter, serving as a path for the stent insertion.
Catheter: A catheter may be included to help drain urine from the bladder or to aid in the insertion of the guidewire.
Dilators: Dilators are tapered instruments used to gently stretch the ureter and facilitate the passage of the ureteral stent.
Delivery Sheath: A delivery sheath is a tube-like device used to guide the stent into the ureter and assist with its proper placement.
Introducer: An introducer may be included to help introduce and position the stent delivery system.
Syringes: Syringes of various sizes may be provided for the injection of contrast dye or saline solution for imaging and flushing purposes.
Accessories: The set may contain additional accessories such as connectors, clips, or clamps used during the stent placement procedure.
Some common scenarios where ureteral stents are used and their typical duration include:
- Ureteral Obstruction: If there is a blockage in the ureter, a stent may be placed to bypass the obstruction and allow urine to flow. The stent is generally left in place until the obstruction resolves, which can be a few days to a few weeks.
- Kidney Stone Treatment: Ureteral stents can be used in conjunction with other treatments, such as lithotripsy or ureteroscopy, to help with the passage of kidney stones. In such cases, stents are often left in place for a few days to a few weeks to aid in stone clearance and prevent complications.
- Ureteral Surgery or Repair: Following ureteral surgery or repair, a stent may be placed to provide temporary support and promote healing. The duration of stent placement can vary depending on the complexity of the procedure and the surgeon's recommendation, typically ranging from a few days to a few weeks.
