Double J Stents placed inside the ureter during surgery to ensure drainage of urine from the kidney into the bladder.
J shaped curls are present at both ends to hold the tube in place and prevent migration, so it is called as “Double J stent”.
Double J stent is also called as DJ stent, JJ Stent, Ureteric stent, Ureteral Stent, Double Pigtail Ureteral Stents.
Double J stent made from tecoflex polyurethane and it is available in the sizes ranging from 3 fr – 7 fr and length 16cms – 26cms.
DJ Stents are available with a single loop, multiloops, open ends and closed ends.
DJ Stents available in white and blue colors.
Durable with superior bio-compatibility.
A thin wall designed for maximum drainage.
Tapered at both ends – for easy insertion.
Minimized tissue irritation with easy but rapid Traumatic insertion.
Smooth surface for easy insertion.
Highly radio-opaque for better visualization.
It can be used for long term indwelling.
Pigtail shape prevents stent migration.
The ureters may become blocked as a result of a number of conditions, including:
● Kidney stones
● Blood clots
● Postoperative swelling
A ureteral stent may also be placed during or after urinary tract surgery to provide a mold around which healing can occur, to divert urine away from areas of leakage, to manipulate kidney stones or prevent stones from moving prior to treatment, or to make the ureters more easily identifiable during surgical procedures.
The procedure is usually performed with the patient asleep (under general anaesthesia). Sometimes a local anaesthetic, with or without sedation, is administered.
During this procedure, a tube with a tiny optic camera is inserted through the urethra into your bladder. The bladder is inspected, and the ureteric opening is located. The urologist may use x-ray images taken with a contrast agent (dye) in the ureters to assess the urinary tract and to locate the obstruction.
The stent is placed during surgery by sliding it over a guidewire placed in the ureter (the tube that drains urine from the kidney into your bladder).
