Abstract

Objective: To describe an unusual site of hemorrhage in a case of anticoagulant rodenticide toxicity.

Case summary: A dog treated for Brodifacoum anticoagulant rodenticide intoxication was referred for treatment of thrombocytopenia and dysuria. Sonographic examination revealed a large blood clot within the urinary bladder, extending proximally along both ureters, and a bilateral hydronephrosis. In this dog, management of the vitamin K1-dependent coagulopathy was unusually complicated by uremia and thrombocytopenia.

New information provided: This is the first reported case of hydronephrosis secondary to anticoagulant rodenticide intoxication in a dog.
