Unilateral idiopathic renal hematuria in a dog

Resumen

Idiopathic renal hematuria is diagnosed in situations where the cause of hematuria is not clear, even after ruling out all possible differential diagnoses. A 14-year-old female Cocker Spaniel with continuous hematuria as the only clinical sign for two months. Concomitant changes were ruled out by blood tests, urinalysis, and abdominal ultrasonography. It was evidenced that hematuria originated from the left kidney through ureteral catheterization and the diagnosis of idiopathic renal hematuria was determined by excluding other possible causes of renal hematuria. Idiopathic renal hematuria is a rarely reported disease but has great importance as a differential diagnosis in cases where the main clinical sign is hematuria.
