Case Study

Right hydronephrosis and mild hydroureter in an 8 year old female spayed DSH cat

An 8-year-old female spayed DSH cat was presented for weight loss, anorexia, and weakness. The cat was currently on phenobarbital. The only significant abnormality on physical examination was right renomegaly. Urinalysis showed 3+ hematuria, 1+ proteinuria, and elevated microalbuminuria. Azotemia and hyperamylasemia were evident on serum biochemistry.
