Ureteric stent
This medical device related article is a stub.
A ureteric stent (also known as a ureteral stent) is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney to the bladder. These stents are commonly used in the field of urology to ensure the patency of the ureter, especially after procedures such as kidney stone removal or to bypass a blockage caused by a tumor.
Indications[edit | edit source]
Ureteric stents are indicated in various clinical scenarios, including:
- Kidney stones: To facilitate the passage of stones or after lithotripsy
- Ureteral stricture: To maintain ureteral patency
- Malignancy: To bypass obstruction caused by cancer
- Post-surgical: To ensure drainage after urological surgeries
Types[edit | edit source]
Ureteric stents come in various designs and materials. The most common type is the double-J stent, named for its shape, which has a curl at each end to prevent migration. Stents can be made from materials such as polyurethane, silicone, or metal.
Placement[edit | edit source]
The placement of a ureteric stent is typically performed using cystoscopy, a procedure where a thin tube with a camera is inserted through the urethra into the bladder. The stent is then guided into the ureter. This procedure is usually done under local anesthesia or sedation.
Complications[edit | edit source]
While ureteric stents are generally safe, they can be associated with complications such as:
- Infection: Due to the presence of a foreign body
- Stent migration: Movement of the stent from its original position
- Encrustation: Mineral deposits forming on the stent
- Hematuria: Blood in the urine
- Pain: Discomfort in the bladder or kidney area
Removal[edit | edit source]
Stents are usually temporary and need to be removed or replaced after a certain period, typically a few weeks to a few months, depending on the underlying condition. Removal is also performed via cystoscopy.
