An unusual case of traumatic dorsolateral sacral hernia with retroflexion of the urinary bladder in a cat

Perineal hernias are rarely seen in cats and can be caused by congenital or trauma. The urinary bladder is the most herniated organ and was being observed in prepubic, ventral perineal, umbilical, or caudoventral abdominal regions.

A 1-year-old female domestic short-haired cat was presented to the Animal Hospital of the Near East University Faculty of Veterinary Medicine with complaints of urinary retention as well as the inability to defecate. The patient owner reported that the cat had been struck by a car around 4 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 herniated through a muscular tear to the right dorsolateral pelvic region.

Unusual case report of a sacral hernia resulting from a traumatic rupture of the sacral muscles together with urinary bladder retroflexion was reported in a cat.
