A case of diagnosis and death reason analysis of cattle cystitis and renal failure

A 5-month-old yellow cattle was treated for vulvar bleeding for more than 20 days without any improvement and went to a doctor. In order to diagnose the disease, the cattle was diagnosed by clinical examination, blood routine index examination and blood biochemical index examination. The results showed that the number of white blood cells, lymphocytes, monocytes, and neutrophils of the cow were all higher than the reference values, and the number of red blood cells, hemoglobin concentration, hematocrit, and the number of platelets were lower than the reference values, which indicated that the cattle had severe anemia and infection. In addition, the concentrations of the bovine creatinine and urea were higher than the reference values, which inferred that the cattle had renal failure. The cattle died on the second day after the examination. In order to find out the cause of death of the affected cattle, pathological necropsy and histopathological examination were performed on the dead cattle, results showed that the cattle had joint fibrocapillary hemangioma, bladder inflammatory exudation and renal atrophy. Joint fibrocapillary hemangioma appeared late in this case, and capillary hemangioma is a relatively common benign tumor. Based on this, it was inferred that joint fibrocapillary hemangioma was not the cause of death of the cattle, mainly due to cystitis and renal failure.
