Swollen Kidneys

Swollen Kidneys

Swollen kidneys, medically known as renomegaly, is a condition in which one or both kidneys become abnormally enlarged. The kidneys of a pet are more enlarged than usual. This can occur in both cats and dogs and is a very serious condition. Some of the more common health issues that can cause swollen kidneys in pets include infections, inflammation and cancer. Other issues that can cause renomegaly are urinary tract obstructions, cysts in the urinary tract and abscesses.

How to Recognize

Swollen kidneys can only be confirmed with an ultrasound, X-ray, or palpation, but symptoms such as an abnormally large abdomen typically signify swollen kidneys. Try to palpate your pet's kidneys to feel for swelling and tenderness.

Causes of Swollen Kidneys

Swollen kidneys can be due to an infection, an inflammation, various urinary problems, or cancer.


Your veterinarian will use an X-ray or ultrasound to view your pet's kidneys and will take blood and urine samples to perform tests.

Pet Insurance

When adding a dog or cat to your family you want to make sure your pet is happy, healthy and protected. During its lifetime your pet is exposed to many illnesses and diseases and some breeds are affected by a congenital disease which is a condition existing at birth. At these moments when your pet is ill or maybe needs surgery, you want to be protected for the unexpected and high veterinarian costs.
