Kidney Stone DJ Stenting

When a kidney stone blocks the normal flow of urine from the kidney to the bladder, it can cause pain, infection, and kidney damage. A DJ stent is a soft, flexible tube inserted into the ureter to bypass the blockage, ensuring uninterrupted urine flow. It is called a “Double J” stent because both ends are curled—one in the kidney and one in the bladder—to keep it securely in place.

DJ stenting is commonly done before or after stone removal procedures such as URS (ureteroscopy), PCNL, or ESWL. It is usually placed under local or general anesthesia using a cystoscope. Patients can resume most daily activities with the stent in place, though they may experience mild urinary symptoms. The stent is typically removed after 1–6 weeks, once healing or stone clearance is complete.
