Core Advantages

The Absorbable Medical Suture Animal Urinary Stent Catheter Suitable Dogs Cats 3Fr 4Fr is engineered specifically for veterinary clinicians tackling feline lower urinary tract disease (FLUTD), acute urethral obstruction, and complex reconstructive urogenital surgeries. By pairing high-grade polymer catheters with precision absorbable surgical sutures, this kit delivers dependable stenting, drainage, and tissue repair while minimizing urethral trauma.

• Atraumatic Insertion & Low Friction: Designed for tortuous and inflamed feline/canine urethras. The ultra-smooth surface profile drastically curtails mucosal abrasion, spasms, and secondary strictures.

• Superior Anti-Encrustation Performance: The medical-grade polymer matrix actively resists mineral deposition (struvite and calcium oxalate crystal adherence), sustaining high patency during indwelling periods.

• Optimal Biomechanical Flexibility: Formulated to remain firm during initial insertion, then soften at physiological body temperature to prevent bladder-wall micro-perforation.

• Continuous Radiopaque Traceability: Engineered with an integrated barium sulfate radiopaque line for rapid radiographic verification under X-ray or fluoroscopy.

• Sterile Absorbable Suture Integration: Eliminates stressful postoperative suture removals in delicate procedures like Perineal Urethrostomy (PU), reducing infection pathways and patient anxiety.

Technical Specifications & Parameters

Material Comparison: PU vs. Silicone vs. PVC

The success of urinary catheterization hinges on biocompatible material selection:

1. Polyurethane (PU) vs. Traditional PVC:

   • PVC contains plasticizers that can leach into surrounding tissue. It is rigid, inducing friction lesions and severe urethral inflammation.

   • PU (Our Product) exhibits thermo-softening properties. It maintains enough column strength for controlled placement, then yields to anatomical curves at internal body temperatures, making it safe for days of indwelling.

2. Medical Silicone vs. Latex:

   • Latex triggers high cytotoxicity, mucosal edema, and rapid crystal encrustation.

   • Silicone / Advanced PU Blends maintain exceptional chemical neutrality, low protein binding, and soft elasticity, extending safe catheterization windows.

3. Absorbable Suture (PGA/PGLA) vs. Non-Absorbable Monofilament:

   • Non-absorbable threads (nylon, polypropylene) demand manual suture removal, risking tissue tearing and requiring secondary sedation in reactive animals.

   • PGA/PGLA sutures degrade naturally via hydrolysis, offering dependable tensile holding strength for 14–21 days and dissolving cleanly without foreign-body granuloma formation.

Why Choose This Veterinary Stent Kit?

• Engineered for Difficult Catheterizations: The 3Fr profile passes seamlessly through the anatomical flexure of the tomcat penis, avoiding false passage creation.

• Streamlined Surgical Workflow: Incorporates both the functional stent and corresponding suture sizes, ensuring surgeons have sterile, matched consumables during emergency PU surgeries or cystotomies.

• Reduced Clinical Re-Obstruction: Polished eyelets promote uninterrupted urine clearance, washing away debris and small calculi before they consolidate into secondary blockages.

Intended Uses & Target Applications

• Intended Users: Board-certified veterinary surgeons, companion animal general practitioners, emergency/ICU veterinary staff, and veterinary university clinics.

• Clinical Applications:

  • Emergency relief of feline urethral plugs and acute urinary blockages.

  • Pre- and post-operative management of canine cystic and urethral urolithiasis.

  • Stenting and surgical anchoring during feline Perineal Urethrostomy (PU) and canine urethrostomy.

  • Internal splinting and scaffold healing following traumatic urethral laceration or pelvic fractures.

Frequently Asked Questions (FAQ)

Q1: How do I choose between the 3Fr and 4Fr options?

A: Select 3Fr (1.0 mm) for routine feline unblocking, adult male cats, and toy dog breeds under 5 kg. Reserve 4Fr (1.35 mm) for larger domestic cats, female feline stenting, or male dogs ranging from 5 to 15 kg.

Q2: What is the maximum recommended indwelling duration?

A: The typical indwelling span ranges from 3 to 7 days. While the medical-grade PU material can safely dwell up to 14 days under sterile closed drainage, early removal is advised once clear, unhindered urine flow is established.

Q3: How long does the included absorbable suture maintain tissue support?

A: The PGA/PGLA suture maintains roughly 65% tensile strength at 14 days and over 40% at 21 days, achieving complete absorption through hydrolysis within 60 to 90 days.

Q4: Are the drainage eyelets smooth enough to avoid tissue suction?

A: Yes. The lateral drainage eyes are precision-molded and heat-polished to eliminate burrs and sharp edges, preventing mucosal invagination and trauma during aspiration or bladder drainage.

Q5: Can the catheter be used with a guide wire (stylet)?

A: Yes. The kit supports introduction via a dedicated blunt-tipped guidewire to manage difficult, spasm-prone urethral passages. Always withdraw the stylet immediately once urine return appears at the Luer hub.

Q6: What is the recommended technique for anchoring the catheter?

A: Utilize the suture wings near the hub. Secure the wings directly to the prepuce or perineal skin using the included absorbable suture via a stay-stitch or finger-trap friction hitch. Always fit the animal with an Elizabethan collar.

Q7: Does this catheter build up struvite or oxalate deposits easily?

A: No. The high-purity medical polyurethane features an ultra-smooth internal lumen that resists proteinaceous binding and crystalluria adhesion far better than standard latex or polyethylene tubes.

Q8: Does the hub connect to standard infusion and collection equipment?

A: Yes. The hub features a universal Luer Lock interface compatible with standard closed urinary collection bags, extension sets, and eccentric tip or Luer syringes for therapeutic bladder lavage.
