RECURRENT URETHRAL OBSTRUCTION SECONDARY TO IDIOPATHIC RENAL HEMATURIA IN A PUPPY

A seven-month-old, neutered male Catahoula leopard dog cross was prese nted for recurrent urethral obstruction and intermittent hematuria. Af ter exploratory laparotomy and ventral cystotomy, unilateral idiopathi c renal hematuria was diagnosed based on gross observation of hematuri a from the left ureteral catheter. The hematuria resolved after nephre ctomy of the left kidney. The histopathological diagnosis was multifoc al, acute congestion and intratubular hemorrhage. Although idiopathic renal hematuria has been described previously, this puppy was unique b ecause the hematuria caused recurrent, complete urethral obstruction.
