Abstract
Background: Perineal hernias are rarely seen in cats and can be caused by congenital or trauma. The urinary bladder is the most herniated organ and were been observed in prepubic, ventral perineal, umbilical or caudoventral abdominal regions.
Case Description: A one-year-old, female domestic short-haired cat was presented to the Animal Hospital of the Near East University Faculty of Veterinary Medicine with the complaints of urinary retention as well as the inability to defecate. The patient owner reported that the cat had been struck by car around four months previously, which resulted in a pelvic fracture. On clinical examination, a fluctuating mass was detected in the dorso-lateral region of the pelvis. After radiographic and ultrasonographic examination, the mass was diagnosed as the urinary bladder. A cystopexy operation was performed on the urinary bladder, which had been herniated through a muscular tear to the right dorsolateral pelvic region.
Conclusion: The objective of the case report present an unusual case involving a sacral hernia resulting from a traumatic rupture of the sacral muscles together with urinary bladder retroflexion in a cat.
