STENT INSERTION
URINARY STENT INSERTION
A urinary stent, commonly called a ureteral stent or a double-J stent, is a thin, flexible tube inserted into the ureter to maintain urine flow from the kidney to the bladder. It helps relieve or prevent obstruction of the urinary tract.
Urinary stents are inserted in a variety of urological and surgical situations, including:
1. Ureteral Obstruction due to stones, tumors, external compression from lymph nodes or pelvic masses.
2. Post-Urological Procedures
- After ureteroscopy or stone removal
- To prevent or manage ureteral edema or trauma
- Following pyeloplasty, ureteral reimplantation, or urological reconstruction
3. Strictures or Injury of the ureter
4. Infection or Inflammation
- Obstructive pyelonephritis (emergency decompression)
- Ureteritis with associated obstruction
5. Pre-Radiation or Chemotherapy
- To maintain ureteral patency in patients undergoing pelvic radiation or chemotherapy
