Urinary problems can be stressful and, in some cases, life-threatening for pets. When bladder stones, strictures or repeated blockages occur, normal urination becomes difficult or impossible. In these situations, urethrostomy surgery can be a lifesaving procedure.
Although more commonly performed in male cats, urethrostomy surgery is also an important option for certain dogs with chronic urinary obstruction. Understanding when this surgery is needed and what it involves helps owners feel more confident in making decisions about their pet’s care.
What Is a Urethrostomy?
A urethrostomy is a surgical procedure that creates a new opening in the urethra, allowing urine to bypass a narrowed or obstructed section.
In simple terms, urethrostomy surgery creates a wider, more accessible exit for urine. This reduces the risk of blockage, especially in pets with recurring urinary problems.
Why Might a Pet Need This Surgery?
Urethrostomy surgery is typically recommended in cases of:
- Recurrent urinary blockages
- Chronic bladder stones that cannot be managed medically
- Urethral strictures (narrowing due to scar tissue)
- Trauma to the urethra
- Certain congenital abnormalities
In male cats, blockages are often caused by crystals or inflammation. In dogs, urethrostomies are more commonly performed for recurrent stones or strictures.

What Happens During the Procedure?
During urethrostomy surgery in dogs and cats, the surgeon creates a new urinary opening in a wider part of the urethra.
The exact technique depends on the species and size of the pet:
- Cats typically undergo a perineal urethrostomy, in other words the opening of the urethra at the tip of the penis is enlarged to allow any stones or crystals to move out more easily
- Dogs may have a scrotal or perineal urethrostomy depending on the location of the obstruction. The opening to the urethra is usually made in the area that the scrotum is positioned. In dogs that are intact, they may need to be castrated in order to create space for the new urethral opening.
The procedure is performed under general anaesthesia with full monitoring and careful surgical technique.

What Is Recovery Like?
Recovery after urethrostomy surgery in dogs and cats involves:
- Pain management
- Monitoring for normal urination
- Preventing licking or trauma to the surgical site
- Follow-up checks to ensure proper healing
Most pets recover well with appropriate care, although the first 10–14 days are critical for healing.
Does Surgery Cure the Underlying Problem?
It’s important to understand that urethrostomy surgery in dogs and cats does not cure the underlying cause of urinary disease.
Pets may still develop:
- Bladder stones
- Urinary tract infections
- Inflammation
However, the surgery greatly reduces the risk of life-threatening urinary obstruction, which is often the primary concern.
Long-Term Management
After urethrostomy surgery in dogs and cats, long-term care focuses on preventing recurrence.
This may include:
- Prescription urinary diets
- Encouraging increased water intake
- Regular urine monitoring
- Managing underlying conditions
Routine check-ups remain essential.
When Do We Recommend This Surgery?
We consider urethrostomy surgery in dogs and cats when:
- A pet has had multiple urinary blockages
- Medical management is unsuccessful
- There is a high risk of recurrence
- The pet’s quality of life is affected
This is always a carefully considered decision, made in discussion with the owner. It is important to remember that the pet will still have normal bladder control, they merely urinate through a different opening.
In Summary
Urethrostomy surgery in dogs and cats is a serious but often lifesaving procedure. While it does not cure the underlying disease, it can prevent repeated blockages and dramatically improve quality of life.
If your pet has experienced recurrent urinary issues, we can help you explore the best options for long-term management.
