A DJ stent is designed to temporarily relieve obstructions or promote healing in the urinary system. It’s commonly used to treat conditions such as kidney stones, ureteral strictures (narrowing), or after surgeries involving the ureters (the tubes that carry urine from the kidneys to the bladder).
The stent is a thin, flexible tube typically made of silicone or polyurethane. It has a unique “double-J” shape, resembling the letter J, with curls at both ends. These curls help anchor the stent in place: one end sits in the kidney, and the other in the bladder.
