The helper must firmly hold the handler during the procedure. While holding the pusher in place, pull out the conductor. Period of implantation of a two-loop ureteral stent Silicone, Biosoftduo, Vortek 12 months PU-S polyurethane; 3 months Polyurethane PU-R / PU 30 days Polyamide-polyester (PA-PE) 30 days Two-loop ureteral stent: Indications for use -Drainage of the upper urinary tract with fistulas or blockage of the ureter. -Stending for cicatricial stenosis. Radiopaque two-loop ureteral stent with open renal and vesicular ends, with lateral openings on the straight part. The length and diameter of the stent are indicated on the product label next to the kit part number.
Guidewire: Guidewire selection for sets without guidewire: The insertion of a two-loop ureteral stent is recommended using a 150 cm guidewire: -When using a pusher from FR / CH 4.8 to FR / CH 6, a guidewire should be used 0.35 inches (0.89 mm) across. -When using a pusher size FR / CH 7 and larger, use a conductor with a diameter of 0.35 "or 0.38" (0.97 mm). The outline of the stent on the label indicates the presence or absence of the guidewire being removed. The following observation For this reason, after the installation of the catheter, the patient should be constantly monitored and the presence of the indicated side effects should be inspected. To assess the effectiveness of the installed stent and identify complications, it is recommended to carry out periodic observation using radiation, ultrasound and endoscopic methods. The stent should be removed if the drainage obstruction due to encrustation develops, with all signs of infection in the area of the installed stent, or with signs of displacement or rupture. The choice of stent traits is made by the doctor.
The doctor is responsible for any of its uses that are not indicated in the "Indications" section. These kits can only be used by prepared specialists. Unnecessary phenomena The following unnecessary phenomena are known (their development, but to a significant extent depends on the patient's condition) infection, narrowing of the catheter lumen, obstruction, ruptures, displacement, symptoms of bladder irritation, pain, hematuria, erosion. Some unnecessary phenomena may be associated with the installation procedure itself. Among them are those associated with the conductor: perforation of the wall of the ureter or burns due to contact with electrosurgical equipment. If the planned stent placement period exceeds one week, the suture should be removed for retrieval.
For sets containing a wire, wire properties are listed in the wire annotation. For kits that include a ureteral catheter, the length and diameter of the catheter are indicated on the product label. This flushing catheter, supplied with a Luer lock connector, can be used to insert a guidewire or contrast agent. Unconnected pusher. The length, cross-section, and radiopacity of the pusher are indicated on the product label.
For kits containing a clip: a clip that is fixed to the push rod allows the conductor to be clamped. Performed cystoscopically, usually under local anesthesia. The radiopaque ring allows you to control the position of the pusher during stent insertion under fluoroscopic guidance. Advice for the patient Store in a dry, cool place protected from light. If using a kit containing a hydrophilic guide, refer to the specific instructions for use. Under fluoroscopic and endoscopic guidance, first insert the flexible end of the guidewire up to the renal pelvis.
Remove the pusher, make sure it is intact.
Double Loop Ureteral Stent Set Flushing: The graduation on the catheter is not for measurement purposes, but for ease of placement. For catheters with a stylet: Before inserting the catheter, make sure that the stylet is simply passing over the catheter, and make sure that the stylet is positioned appropriately and does not protrude through its opening. After inserting the catheter, make sure it is inserted correctly and then remove the stylet. Introduction in case of damage to the packaging is prohibited. Re-sterilization is prohibited. The product must be disposed of after use.
As a result of the manufacturing process, the fixture may contain particles of silicone. When using a contrast medium, it is recommended to perform the following actions: - dilute the contrast medium by 50 percent with a physiological substance; - deliver a bolus quickly. Patients should be made aware of stent placement and the need for constant monitoring of its condition.
Patients should immediately notify the treating doctor of any decisions that arise. The administration of a contrast agent can lead to side effects. Therefore, observe the precautions that are indicated in the annotation for the use of this product.
