Watching your cat struggle with a ureter obstruction is one of the most distressing experiences any owner can face. When standard treatments are not effective, SUB surgery for cats is often a highly effective solution. It is an effective method to bypass damaged ureters, helping your cat return to normal comfort and behaviour.
At The Cat Vet, we focus on long-term solutions rather than short-term fixes. With advanced bypass procedures, we address the underlying cause, reducing the risk of future emergencies and improving long-term quality of life.
When your cat is hurting, you need a team you can trust. Our dedicated team is here to guide you through every complex decision.
Understanding SUB Surgery for Cats and When It’s Necessary
If your cat is suffering from a complete ureteral obstruction – specifically those caused by stonesand medically management is no longer suitable. This is where a Subcutaneous Ureteral Bypass(SUB) comes in. It is a small, implanted device that allows urine to flow from the kidney to the bladder, completely skipping the blocked or damaged area.
- When standard surgery fails: Sometimes the ureter is too damaged or narrow to repair.
- Saving the kidneys: Restoring urine flow is critical to prevent permanent kidney damage.
- The anatomy of the device: It is a specialised system with a locking loop, a catheter, and a small port that allows it to be flushed, which is required every 3-6 months.
- Long-term management: For cats facing chronic stone issues, this is often the kindest way to keep them comfortable.
The Life-Saving Benefits of Cat Urinary Blockage Surgery
While the term cat ureteral blockage surgery may sound concerning, it is often the most humane and effective way to restore your cat’s quality of life. The SUB system circumvents these tiny, fragile structures, significantly reducing the risks involved with standard repair.
- Higher success rates: Research consistently demonstrates that this procedure is more effective for complex ureteral obstructions than conventional ureterotomy.
- Reduced recovery stress: Because the device is specifically designed for feline anatomy, recovery is often smoother and faster.
- Improved comfort: Relieving pain from the obstruction significantly improves your cat’s behaviour at home.
- Preventive maintenance: The subcutaneous port allows our team to easily monitor the system and flush it if it ever becomes necessary.

Frequently Asked Questions
1. Is SUB surgery for cats painful?
Pain is carefully managed. We use appropriate pain management during and after the operation, so your cat stays comfortable and relaxed during recovery.
2. What are the signs my cat needs urgent help?
If you notice your cat straining in the litter box, crying out in pain, hiding away more than usual, or just acting lethargic, contact us immediately.
3. Does this surgery ensure no more blockages in the future?
It significantly reduces risk by bypassing the damaged ureters entirely. That said, monitoring their behaviour and following an appropriate diet remains essential for long-term health.
4. Will my cat need special food after this?
Usually, yes. We’ll likely suggest a specific diet designed to keep their mineral levels steady to reduce the risk of further crystal formation or urinary stones.
