Long Term Ureteral Stent
Product Features
● Indwelling time of 3-12 months, significantly reducing the frequency of replacement, and alleviating the pain and infection risk of repeated catheterization for patients.
● Made of medical-grade silicone material, with minimal irritation to the urinary tract mucosa and slight foreign body sensation, suitable for long-term indwelling in the body.
● Utilizing a pigtail loop, self-shape memory, or suture fixation, effectively preventing stent migration or extrusion.
● Hydrophilic coating/hydrogel coating reduces bacterial adhesion and crystal deposition, lowering the risk of encrustation and infection.
Structure and material
● The stent body adopts a hollow multi-lateral porous tubular design, with pigtail rings or shape memory structures at both ends to achieve anti-migration fixation. The dual independent channels support simultaneous drainage and irrigation, and the radiopaque markers facilitate precise positioning under X-ray.
● The core is made of medical-grade silicone, which exhibits excellent biocompatibility, softness, and anti-encrustation properties. The surface can be coated with a hydrophilic layer or a hydrogel layer to reduce friction and infection risks.
Instruction for use
● The length of catheter is usually calculated base on the baseline of renal pelvis in X-ray film.
● Accurate measurement will improve the drainage effect and the patient's comfort.
● Insert the guidewire into the affected ureter: send the guide wire to the renal pelvis along Urethra, bladder and ureter.
● After confirming that the guidewire reached the renal pelvis, push catheter along the guidewire with the help of a pusher, and push catheter one end in the renal pelvis and one end in the bladder.
● When catheter is placed, the clip can be clamped on the guide wire to prevent the pusher from retreating, and the position of the clip can be adjusted with the advancement of catheter and pusher.
● After confirming the position of catheter, hold the pusher in hand, withdraw the guidewire, and withdraw the pusher.
● Successful placement of catheter, regularly check the patient's condition, confirm the time to remove or replace Catheter;Successful placement of catheter, regularly check the patient's condition, confirm the time to remove or replace Catheter.
● After Catheter is taken out, it will be collected and treated in a centralized manner by the hospital.
