Your cat will be treated on an outpatient basis unless it is suffering from dehydration or renal failure. Treatment will begin with diagnosing and treating the underlying cause, maintaining fluid balance with intravenous fluids, if necessary, and replenishing minerals and electrolytes. If your cat is otherwise healthy, a normal diet and normal exercise will be advised.
Drugs prescribed by your veterinarian will vary according to the underlying cause of the renomegaly. However, drugs that may have a toxic effect on the kidneys should be avoided.
Your veterinarian will want to see your cat during regular follow-up examinations, where he or she will assess the cat's physical recovery and hydration status.
If your cat's symptoms return, you will need to contact the veterinarian immediately. Possible complications of renomegaly include kidney failure and hormone imbalances that mimic hormone-producing cancers.
