Double J StentTunisia
What is a Double J Stent?
The Double J stent (also called a ureteral stent or JJ stent) is a thin, flexible tube made of silicone or polyurethane, with "J"-shaped curls at both ends. It is placed inside the ureter (the tube connecting the kidney to the bladder) to maintain its patency. One end of the stent sits in the kidney (renal pelvis), and the other in the bladder. This device allows urine to drain from the kidney to the bladder and prevents or treats ureteral obstruction (stone, stricture, tumor, external compression). The stent is called "Double J" because of the shape of its ends, which prevent migration.
When is Double J Stent Placement Indicated?
The Double J stent is indicated in many urological situations. It is used in cases of ureteral obstruction by a stone during severe renal colic. It is also placed in preparation for laser ureteroscopy. The stent is indicated for ureteral strictures of inflammatory or post-traumatic origin. It allows the treatment of extrinsic compression by a tumor or pregnancy. In cases of ureteral or bladder tumor, it serves as a temporary treatment. It protects the ureter during extracorporeal lithotripsy by facilitating the elimination of fragments. For a urinary leak, it diverts urine and allows healing. Finally, it restores renal drainage in cases of obstructive renal failure.
How is a Double J Stent Placed?
The placement of a Double J stent is a minimally invasive endoscopic procedure. It is performed under general or spinal anesthesia. The retrograde approach, through the natural urinary tract, is the most common. The urologist inserts a cystoscope through the urethra into the bladder. A metal guidewire is passed into the ureter up to the kidney. The Double J stent is then slid over the guidewire into the correct position. The position is verified by fluoroscopy to ensure safety. The antegrade approach, through percutaneous puncture of the kidney, is rarely used. It is reserved for cases where the ureter cannot be catheterized. The procedure lasts 15 to 30 minutes. Hospitalization is often outpatient or for 24 hours.
Is Double J Stent Placement Painful?
The placement of the Double J stent is performed under general or spinal anesthesia. Therefore, no pain is felt during the procedure. After placement, burning or discomfort during urination may occur. Frequent urges to urinate (pollakiuria) and urinary urgency are possible. A small amount of blood may be present in the urine (microscopic hematuria). Lower back pain at the end of urination, related to vesicorenal reflux, is common. These symptoms are transient and improve within a few days. Painkillers and antispasmodics are prescribed for relief.
What are the Advantages of the Double J Stent?
The Double J stent offers many advantages for patients. It is minimally invasive, as it is placed through natural pathways without an incision. It allows effective renal drainage, thus preventing obstructive renal failure. By lifting the obstruction, it rapidly relieves renal colic. It protects the ureter during stone fragmentation. It also facilitates the passage of stones by dilating the ureter. Finally, it promotes the healing of fistulas by diverting urine.
What are the Risks and Possible Complications?
The risks associated with the Double J stent are rare and generally manageable. A urinary tract infection, such as pyelonephritis, is prevented by antibiotic prophylaxis. Hematuria, or blood in the urine, is common but transient. Irritative symptoms, such as pollakiuria or lower back pain, are frequent but tolerable. Migration of the stent is rare and may require repositioning. Obstruction of the stent by debris may occur, necessitating a change. Ureteral perforation is exceptional, occurring in less than 1% of cases. Ureteral stricture secondary to the stent is rare. Finally, stone formation on the stent (encrustation) requires early replacement.
How Long Does the Double J Stent Stay in Place?
The duration the Double J stent remains in place depends on the indication. For a ureteral stone, the stent is kept for 2 to 4 weeks after fragmentation. In cases of stricture, it is maintained for 6 to 12 weeks, sometimes longer, until surgery. For tumor compression, the stent may be permanent and changed every 3 to 6 months. During pregnancy, it remains in place until delivery. In cases of fistula, it is kept until complete healing. Stent replacement is performed on an outpatient basis, under local or short general anesthesia. It is done every 3 to 6 months in cases of prolonged retention. This helps prevent stent encrustation.
How is the Double J Stent Removed?
The removal of the Double J stent is a simple procedure performed on an outpatient basis. It is usually done under local anesthesia, with an anesthetic gel in the urethra. The urologist inserts a flexible cystoscope through the urethra into the bladder. The lower loop of the stent is then visualized and grasped with forceps. The stent is then gently removed. The procedure takes about 5 minutes. Under general anesthesia, removal is reserved for cases of severely encrusted stents. After removal, burning during urination may occur for 24 to 48 hours. It is advised to drink plenty of water to limit these symptoms.

Avoid intense physical exertion, such as sports or heavy lifting, for 48 hours. Monitor for warning signs: fever above 38°C, severe pain, or heavy bleeding. Inability to urinate requires prompt consultation. Strictly respect the stent removal date to avoid encrustation. Finally, take prescribed painkillers and antispasmodics in case of discomfort.
