Double J Ureteral Stent Set
The double J ureteral stent set is a medical device used to treat patients with kidney stones or other urinary tract conditions. The stent set consists of two stents, one for each ureter, and is inserted through the patient's urinary tract. The stents are then positioned in the ureters, where they help to keep the ureters open and allow urine to flow freely.

The double J ureteral stent set is a medical device used to treat patients with kidney stones or other urinary tract conditions.

A double J ureteral stent is a tube that is inserted into the ureter (the tubes that carry urine from the kidneys to the bladder) to help relieve a blockage. The stent is made of a soft, flexible material and has two "J" shaped ends. One end is inserted into the kidney and the other end is inserted into the bladder. The stent stays in place for a period of time and then is removed.
A double J ureteral stent is placed by threading it through the ureter and then attaching it to the kidney. The stent is then left in place for a period of time to allow the kidney to heal.
There are a few pros and cons to having a double J ureteral stent. A pro would be that it can help with the drainage of urine from the kidney to the bladder. This can be helpful if you have an obstruction in your urinary tract. A con would be that the stent can sometimes become dislodged and cause pain or discomfort. If this happens, you may need to have the stent removed or replaced.
There are a few alternatives to a double J ureteral stent that your doctor may recommend. These include:
- A ureteral stent with a larger diameter. This type of stent is less likely to become blocked or dislodged.
- A ureteral stent with a different shape. Some stents are designed to conform better to the anatomy of the urinary tract.
- A ureteral stent made from a different material. Some stents are coated with substances that help prevent infection or blockage.
The proximal end of the stent should be completely curled and in the most inferior possible position in the renal pelvis. The secret is to allow the proximal end of the double J stent to coil completely, also move it into position while still leaving the guidewire incompletely inside the distal portion of the stent. Pressure on the dangler/ safety thread keeps the stent, pusher, and guidewire connected as a unit which allows for manipulation and indeed complete stent junking/ relief while leaving the guidewire in place for ureteral access.
Getting the proximal end of the stent to coil in a small renal pelvis can be tricky. A initiative called the"Leslie Flip"is frequently helpful in similar situations. This involves renouncing the guidewire from the proximal end of the stent, also pulling the stent, line, and pusher back into the proximal ureter followed incontinently by sluggishly pushing all of them forward, back into the renal pelvis. The proximal stent tip, with its strong coiling memory, will try its stylish to make a completely indirect coil. This initiative can be repeated if necessary, to gain optimal results. (It's critical to have the dangler/ safety thread in place and under mild traction to be suitable to do this initiative. Else, the stent may not repudiate. This is one of the reasons we recommend leaving the dangler/ safety thread in place until the very end of the procedure.)
Don't cut the dangler/ safety thread until the procedure is completed. As long as the dangler/ safety thread is attached to the distal end of the stent, it holds the stent and the pusher together while the guidewire remains in place between them, keeping them connected and aligned. This basically makes a single unit of these separate particulars which facilitates positioning and allows for the"Leslie Flip" initiative described preliminarily. Cutting the dangler/ safety thread at the morning of the case makes it nearly insolvable to change or indeed manipulate the stent without immolating the guidewire and conceivably losing access. In similar cases, it may be insolvable to recapture ureteral access, which can significantly complicate the case's clinical course. This is the single most helpful tip in double J stent placement and the most generally neglected.
The dangler/ safety thread needs to be removed in a manner that won't move the stent out of position. The dangler thread can fluently be cut and removed at the end of the case as long as the pusher is still in place and the guidewire is always at least incompletely inside the distal end of the double J stent. The incompletely fitted companion line and pusher together stabilize the distal end of the stent and keeps everything adequately aligned with only gentle traction on the dangler thread. Without the thread, there's no way to keep the stent from moving during manipulation or to prize it without losing the guidewire and conceivably ureteral access as well. Once the thread is removed, the guidewire can be snappily withdrawn without dislodging the stent since the pusher will
