A dog experienced urinary bladder rupture due to chronic inflammation, not trauma. This rare veterinary case highlights the need to consider inflammation in diagnosing uroperitoneum.
Area of Science:
- Veterinary Medicine
- Canine Urology
- Surgical Pathology
Background:
- Spontaneous urinary bladder rupture is rare but documented in humans.
- Canine patients presenting with vomiting and anuria often have uroperitoneum.
- Trauma is typically suspected in cases of urinary bladder rupture.
Observation:
- A 10-year-old mixed-breed dog presented with vomiting and anuria.
- Diagnostic imaging revealed urinary bladder leakage.
- Surgical exploration confirmed a urinary bladder tear.
Findings:
- Histopathology showed lymphoplasmacytic cystitis with hemorrhage and fibrosis.
- The chronic inflammation and fibrosis weakened the bladder wall.
- This led to spontaneous perforation without evidence of trauma.
Implications:
- This is the first veterinary case of spontaneous urinary bladder rupture secondary to chronic inflammation.
- Highlights the importance of considering chronic inflammation in the differential diagnosis of uroperitoneum in dogs.
- Emphasizes the need for thorough histopathological examination in cases of unexplained bladder rupture.
