DJ stenting, also known as Double J stent placement, is a common urological procedure used to keep the ureter open and allow urine to flow normally from the kidney to the bladder.
The ureter is the tube that carries urine from the kidney to the bladder. When this passage becomes blocked or narrowed, urine cannot drain properly. In such situations, a thin, flexible tube called a DJ stent is placed inside the ureter to maintain drainage.
The stent has curved ends on both sides, resembling the letter “J”, which helps keep it securely positioned in the kidney and bladder.
Why is DJ Stenting Performed?
DJ stenting is done to relieve blockage in the urinary tract and protect kidney function. It is commonly recommended in the following conditions:
Kidney stones blocking the ureter
Swelling of the ureter after stone removal procedures
Urinary tract infections with obstruction
Narrowing of the ureter (ureteral stricture)
Tumors pressing on the ureter
Congenital abnormalities affecting urine drainage
By restoring urine flow, DJ stenting helps reduce pain, prevent infection, and avoid long-term kidney damage.
Symptoms That May Indicate the Need for DJ Stenting
Patients with ureteral blockage may experience symptoms such as:
Severe pain in the side or lower back
Pain spreading to the groin
Nausea or vomiting
Blood in urine
Frequent urinary infections
Reduced urine flow
Swelling of the kidney (hydronephrosis) detected on imaging tests
If these symptoms are present, doctors may recommend DJ stent placement to relieve the obstruction.
How the Procedure is Done
DJ stenting is usually performed using a minimally invasive endoscopic technique called cystoscopy.
The procedure typically involves:
Administration of anesthesia to ensure patient comfort.
Insertion of a cystoscope (a thin tube with a camera) through the urethra into the bladder.
Placement of the DJ stent inside the ureter using special instruments.
Confirmation of proper positioning with imaging guidance.
The procedure usually takes about 20–30 minutes.
Recovery After DJ Stent Placement
Most patients can return home on the same day or the next day after the procedure.
Some temporary symptoms may occur, including:
Frequent urination
Mild abdominal or flank discomfort
Burning sensation during urination
Small amounts of blood in urine
These symptoms usually improve gradually over a few days.
Duration of the Stent
DJ stents are generally temporary and remain in place for a few days to several weeks, depending on the medical condition being treated.
It is important to remove or replace the stent at the recommended time, as leaving it in place for too long may lead to complications.
Possible Risks
Although DJ stenting is a safe procedure, some complications may occur, such as:
Regular follow-up visits help ensure proper stent management.
