The bladder is a hollow, muscular organ which is located within the pelvis. It stores urine until it is ready to be voided. The most common causes of a ruptured bladder are trauma, such as being hit by a car, falling from a height, gunshot wound or due to a urinary blockage caused by calculi or mucous plugs or bladder cancer. Once the bladder ruptures, urine leaks into the abdomen (known as uroabdomen) resulting in uremic poisoning, a life-threatening condition due to a dangerous build up nitrogenous of toxins in the bloodstream.
Symptoms of ruptured bladder:
Any cat who has had a serious trauma should be evaluated for a ruptured bladder, especially where a pelvic fracture has occurred. Obviously, a traumatic injury will result in a bladder that ruptures quickly, however, if a urinary blockage is the cause, there may have been symptoms of a urinary prior to the bladder rupturing. These would include:
Your veterinarian will perform a complete physical examination of your cat and obtain a medical history from you. If he has been involved in a trauma he will be assessed for a broken pelvis and a ruptured bladder, both of which are common injuries.
Abdominal x-rays and ultrasound will be taken to evaluate the pelvis and bladder.
Bloodwork to evaluate for elevated BUN (blood urea nitrogen), creatinine and potassium levels.
