DJ stenting (Double-J ureteric stenting) is a minimally invasive endoscopic procedure in which a flexible plastic stent (tube) is placed inside the ureter — the tube connecting the kidney to the bladder. The stent has a coil at each end (double-J shape) that holds it in place in the kidney and bladder. DJ stenting relieves ureteric obstruction, maintains urine drainage, facilitates stone passage, and provides post-operative support after urological procedures.
