What is JJ stent used for?
A ureteric stent (also called a J-J stent or double-J stent) is a thin, flexible plastic tube which is curled at both ends to avoid damaging the kidney and urinary bladder and to prevent it from dislocating. The stent is placed so that its upper end is in the kidney and its lower end is in the urinary bladder.
How long does JJ stent take?
Double-J (DJ) stents are among the basic and commonly used tools in urology. The DJ stent generally needs to be replaced or removed within 6 weeks to 6 months to avoid complications like encrustations, stone formation, fractures and blockades of stents.
When should JJ stents be removed?
When should the stent be removed? In some cases the stent can be removed just a few days after the procedure, while in other cases your Urologist may recommend that it stay in place longer. In general, a stent should be removed (or exchanged) within 3 months.
Is JJ stent permanent?
Most ureteral stents are temporary. Your healthcare provider will perform another procedure to remove the stent after the kidney stone passes, infection clears up or other problems resolve. You’ll probably have the stent for a few days or weeks. Some people need stents for months or years.
What is a JJ stent made of?
All ureteral stents are made of polyurethane or silicone; metallic stents are not used in ureters. A double-J ureteral stent is completely internal and has a “pigtail” at each end (Fig. 35-3A). Its proximal coil is situated in the renal pelvis, and its distal coil is situated in the urinary bladder.
Can a stent damage your kidney?
Conclusions: Chronic renal failure caused by encrusted stents in a functionally solitary kidney is a disastrous complication of forgotten stents. Prevention is, of course, ideal, but such cases are still seen despite increasing awareness.
Why is it called a JJ stent?
One or both ends of the stent may be coiled to prevent it from moving out of place; this is called a JJ stent, double J stent or pig-tail stent.
What is JJ stent insertion?
Ureteral Stenting (Double J Stent, JJ Stent) Ureteral stenting (also known as double J stent) is the procedure to place a thin, flexible plastic tube that is temporarily in the ureter to help urine drain from the kidney into the bladder in the case of a blockage. The ureters carry urine from the kidneys to the bladder.
