Overview: What This Product Is

Our Absorbable Medical Suture Animal Urinary Stent Catheter is a single-use, sterile, endotoxin-free device designed for temporary urinary drainage and urethral patency in dogs and cats. Built from biocompatible polyurethane (PU) with full radiopacity, it includes an integrated guide wire for precise placement and a suture plate to secure positioning. Available sizes 3Fr and 4Fr address small-patient needs, including male cats with urethral obstruction (UO) and toy/small-breed dogs.

SKU highlights:

• Sizes: 3Fr, 4Fr (other Fr sizes on request)
• Material: Medical-grade PU, smooth surface, kink-resistant
• Visibility: Fully radiopaque for clear X-ray confirmation
• Placement aid: Guide wire included for controlled, atraumatic insertion
• Fixation: Suture plate for secure external anchoring
• Sterility: EO-sterilized; endotoxin-free if package undamaged
• Intended use: Temporary urinary stenting & drainage in dogs/cats (renal/urethral)
• Single-use only

Why Urinary Stent Catheters Matter Now (Trending Clinical Context)

Companion-animal urinary health continues to draw clinician and pet-owner attention due to the frequency and urgency of feline urethral obstruction and recurrent lower urinary tract disease. Recent guidance and studies keep UO management in the spotlight, offering veterinarians updated protocols—from triage and monitoring to catheter choice and placement technique. In March 2025, the AVMA highlighted research on managing life-threatening hyperkalemia secondary to feline urinary obstruction, underscoring how rapid, reliable urinary decompression and monitoring can be lifesaving.

In 2025, International Cat Care (iCatCare) published consensus guidance on the diagnosis and management of feline lower urinary tract diseases, reinforcing best practices for relieving obstruction, minimizing trauma, and reducing recurrence—areas where small-Fr, atraumatic, well-visualized catheters are central to care.

Public interest in overall pet wellness (weight, hydration, stress reduction) remains a top theme; owner education by veterinarians continues to focus on healthy weight and lifestyle to reduce LUTD risk factors, which also supports preventive care messaging around urinary health.

Takeaway for clinics: A dependable, radiopaque 3–4Fr catheter with guide wire helps speed decompression, confirm tip placement, and reduce insertion trauma in small patients—aligned with modern UO/LUTD guidelines and client expectations.

Key Features & Clinical Benefits

1) PU Construction for Comfort & Control

Smooth, flexible PU reduces urethral irritation vs. stiffer plastics and resists kinking during patient movement.

PU’s biocompatibility supports short-term indwelling use in veterinary patients.

2) Fully Radiopaque for Confident Placement

Integrated radiopaque line provides clear X-ray visibility to confirm depth and position, especially valuable when anatomy is challenging or when repositioning is required.

3) Guide Wire for Atraumatic Insertion

The included guide wire supports Seldinger-style placement: negotiate the stricture with the wire first, then advance the catheter smoothly, with less force—helping reduce mucosal trauma.

4) Suture Plate for Secure Fixation

The low-profile external plate allows straightforward suture anchoring to skin or adhesive dressing, minimizing accidental dislodgement.

5) Sterile, Endotoxin-Free, Single-Use

EO sterilized and labeled endotoxin-free if package undamaged, aligning with infection-prevention best practices and ensuring ready-to-use convenience in emergency settings. (General CAUTI prevention principles emphasize aseptic technique, securement, and removal at the earliest opportunity.)

Indications & Patient Selection

Feline urethral obstruction (UO): initial decompression and short-term stenting to re-establish flow and allow urethral relaxation.

Canine lower urinary tract obstruction: temporary stenting in small-breed dogs, particularly where 3–4Fr is indicated.

Post-procedural urinary diversion: after stone manipulation or urethral swelling.

Support in LUTD management: as part of a broader plan that includes analgesia, antispasmodics, hydration, and environmental/lifestyle adjustments.

Sizing & Specifications

French sizes: 3Fr and 4Fr (custom sizes available)

Length: standard small-patient length; custom lengths available

Tip: soft, rounded, guide-wire compatible

Lumen: optimized for drainage with small outer diameter

Markings: radiopaque line, depth markers (optional)

Connector: standard tapered or luer options for drainage sets

Choosing the size:

Cats & toy-breed dogs: 3Fr is typically chosen for very small or delicate urethras; 4Fr provides improved flow where anatomy permits. Final selection is up to the attending veterinarian based on patient size, obstruction severity, and resistance on insertion. (Consult current UO/LUTD guidelines.)

How to Use (Clinical Summary)

For licensed veterinary professionals only. Follow clinic protocol and local regulations.

1. Stabilize & assess: Address analgesia/sedation and, where indicated, correct hyperkalemia and dehydration in obstructed male cats prior to definitive catheterization.
2. Aseptic prep: Clip, disinfect, and drape per clinic CAUTI prevention policies; prepare sterile field.
3. Wire first: Gently advance the guide wire into the urethra; avoid force.
4. Advance catheter: Track the catheter over the wire; confirm free flow of urine.
5. Confirm position: Use radiography to verify the tip location if needed.
6. Secure: Fix with the suture plate and appropriate dressing; connect to a closed collection system.
7. Monitor & remove: Monitor urine output, hematuria, and comfort; remove as soon as clinically feasible to reduce infection risk.

Infection-Prevention Considerations

While veterinary-specific CAUTI guidelines differ by region, core catheter-care principles remain universal: aseptic insertion, securement, closed drainage, daily assessment, and early removal. Human healthcare infection-control guidance from the CDC—often adapted for veterinary settings—continues to emphasize these practices to lower CAUTI risk.

Frequently Asked Questions (FAQ)

Q1: Is the catheter absorbable?
The catheter body is PU (non-absorbable for strength and control). “Absorbable” here refers to compatible absorbable sutures used with the suture plate when anchoring, if your protocol prefers absorbable material. Custom absorbable components are available on request.

Q2: Can I use 3Fr in all male cats?

Not always. 3Fr is excellent for very small or narrow urethras; 4Fr may provide better drainage in larger cats or small dogs. Follow your UO protocol and judge resistance during insertion.

Q3: How long can the stent remain in place?
Temporary use only—follow your clinic’s CAUTI-prevention policy and remove as early as clinically possible once patency is assured and inflammation subsides.

Q4: Is it safe to place without imaging?
Initial placement is typically performed using gentle technique with guide wire; radiography is recommended whenever position is uncertain or complications are suspected.

Q5: What makes this device different from a standard red rubber catheter?
This stent offers guide-wire control, radiopacity, kink resistance, and a suture plate for securement—advantages when anatomy is challenging or when minimizing trauma is critical.
