Medical Grade PU Veterinary Renal Catheter/Urinary Stent With Stylet 3FR/4FR 120mm/130mm Full Radiopacity for Dog Cat Urinary Tract Diagnosis Drainage ISO / FDA

【1. Product Description】Professional Design, Trusted Quality

This Veterinary Renal Catheter / Animal Urinary Stent is meticulously engineered to address the complex urinary tract anatomy of small animals, specifically dogs and cats.

We deeply understand that veterinary medical procedures demand the highest standards of safety and operational precision. Therefore, this product is manufactured entirely from premium Medical Grade Polyurethane (PU). PU material offers exceptional biocompatibility, combining softness with the necessary degree of rigidity. Once inserted into the animal's body, it significantly reduces irritation to the mucosal tissue, drastically lowering the risk of post-operative inflammation and potential complications.

A core technological feature of this catheter is its Full Radiopacity. This allows veterinarians to clearly and in real-time monitor the catheter's advancement path and final placement under X-ray, fluoroscopy, or CT guidance, ensuring unerring accuracy and preventing accidental insertion into neighboring tissues. Furthermore, each catheter is supplied with a precision Stylet, which remarkably enhances the catheter's pushability and maneuverability within complex and narrowed urinary tract, making the intubation process smoother, reducing procedure time, and mitigating patient discomfort.

【2. Core Applications】Multiscan Solutions in Clinical Veterinary

Leveraging its outstanding performance, this product is extensively utilized in clinical veterinary urological surgery and internal medicine, serving as a critical tool for managing renal and ureteral diseases in small animals:

1. Urinary Tract Drainage & Decompression: Used to relieve hydronephrosis and ureteral dilatation caused by ureteral stones, strictures, tumor compression, or congenital malformations. By establishing a temporary drainage route, it rapidly facilitates the excretion of accumulated urine, lowers intrarenal pressure, and preserves renal function.

2. Diagnosis & Imaging: Assists in performing retrograde pyelography. By injecting a contrast medium through the catheter, it clearly visualizes the internal morphology of the ureter and renal pelvis, enabling precise diagnosis of the obstruction's location and nature.

3. Drug Infusion: For pharmacological therapy, this catheter allows for direct and precise delivery of medications (such as antibiotics, anti-inflammatory agents, or stone-promoting drugs) to specific sites within the renal pelvis or ureter, enhancing local drug concentration and therapeutic efficacy.

4. Post-operative Stenting: Following procedures such as ureterolithotomy (stone removal) or ureteral resection and anastomosis, it is placed indwelling as a stent to maintain luminal patency, prevent post-operative strictures, and effectively forestall urine leakage into the retroperitoneal space, thus promoting wound healing.

5. Sampling & Monitoring: Facilitates the collection of direct urine samples from the renal pelvis for cytology, bacterial culture, and antibiotic sensitivity testing, providing more precise diagnostic data than bladder urine samples.

【3. Technical Specifications】Precise Data, Fully Transparent

The following data is derived from the official product specifications to ensure accuracy:

*Note: Regarding the "Absorbable" characteristic, as the primary material is listed as PU, we recommend confirming with the actual product's biological properties. Typical long-term stents are non-absorbable.

【4. Core Advantages】Why Choose Our Product?

1. Full Radiopacity for Precise Positioning: The entire catheter is radiopaque, making it clearly visible under imaging, significantly enhancing the safety and accuracy of placement.

2. Stylet Design for Superior Control: The accompanying precision stylet provides the required rigidity and maneuverability, allowing veterinarians to effortlessly handle complex obstructions or tortuous pathways.

3. Medical PU Material for Safety: High-quality PU material ensures excellent biocompatibility and appropriate flexibility, guaranteeing long-term safety within the patient and reducing tissue rejection.

4. Double Certification (ISO/FDA): Meets international quality management and safety standards for medical devices, providing a reliable clinical basis and safety assurance for veterinary institutions globally.

5. Single Sterilized Independent Packaging: Employs the highest grade of medical-grade sterile packaging technology to ensure the product is sterile before opening, preventing iatrogenic infections.

【5. Frequently Asked Questions (FAQ)】

Q: How should I choose between 3FR and 4FR sizes?

A: This depends on the patient's body size and specific urinary tract conditions. Generally, 3FR is suitable for smaller cats and small dogs, while 4FR is typical for slightly larger dogs. It is recommended that the veterinarian makes the final decision based on intra-operative imaging or luminal size measured by ultrasound.

Q: Is this catheter suitable for long-term indwelling stenting?

A: While PU material has excellent biocompatibility, please refer to clinical veterinary guidelines to assess the suitability of the catheter for long-term use. Typically, these types of catheters are common for short-to-medium-term decompression, post-operative transitioning, or diagnostic procedures. The specific indwelling duration should be comprehensively evaluated by the attending physician based on the patient's condition, recovery progress, and risk of encrustation formation.

Q: Do you have stock, and can you provide OEM services?

A: We are the manufacturer, and most conventional specifications are in stock, with a delivery cycle of 7-14 days. We also fully support OEM/ODM customization services, where we can adjust sizes, lengths, or packaging according to your specific clinical needs or brand requirements.
