Abstract:
A seven-month-old, neutered male Catahoula leopard dog cross was presented for recurrent urethral obstruction and intermittent hematuria. After exploratory laparotomy and ventral cystotomy, unilateral idiopathic renal hematuria was diagnosed based on gross observation of hematuria from the left ureteral catheter. The hematuria resolved after nephrectomy of the left kidney. The histopathological diagnosis was multifocal, acute congestion and intratubular hemorrhage. Although idiopathic renal hematuria has been described previously, this puppy was unique because the hematuria caused recurrent, complete urethral obstruction.
