The bladder empties out of the body through a small tube called the urethra. If the urethra becomes obstructed (blocked off), compressed, or inflamed, this is a life threatening medical emergency and must be attended to by a veterinarian immediately. If the bladder is blocked from releasing urine for too long, this can lead to kidney failure, which may also be fatal.
What are the signs of a urinary blockage?
– Straining to urinate (it may often look like your pet is struggling to have a bowel movement)
– Very small amounts of urine or no urine at all
– Bloody or cloudy urine
– Discomfort when urinating
If you see these signs, don’t wait – call your veterinarian immediately!
Causes and risk factors
– Most common in male cats, but dogs and female cats may also be affected
– Urinary crystals or stones
– Urinary tract infections
– Lesions, scar tissue, or tumors may also cause obstruction
How is an obstruction diagnosed by a veterinarian?
– Palpation of the abdomen (feeling for swelling of the bladder)
– Urine testing (screening for infection or crystals which may lead to obstruction)
– Blood testing (screening for organ function, especially of the kidneys and electrolytes)
– Radiographs of the abdomen (x-rays)
With a urinary obstruction, the blockage must be taken care of as soon as possible. Sedation is often required, and the treatment depends on the severity of the obstruction.
Treatments may include:
– Placement of a urinary catheter
– Surgical removal of stones if too large to pass through a catheter
– IV fluids to rehydrate and to normalize electrolyte levels
– Hospitalization is the best standard of care until the pet is stabilized and able to pass urine on their own
– Medications for pain management and relaxation of the urethra to help with urine flow
– Monitor closely for urine output
– Veterinary approved diet to decrease the chance of re-forming crystals and obstructing again
– Regular urine screening
– Yearly screening urine testing – can help to detect crystals before they become large or numerous
– Urinary protective diets, especially for pets who have a history of urinary tract infections, urinary crystals, or a genetic predisposition
