一例黄牛膀胱炎和肾功能衰竭病例的诊断及死亡原因分析

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

1头5月龄黄牛因外阴部出血,自行治疗超过20 d未见好转遂就诊。为了诊断该牛所患疾病,采用临床检查、血常规指标检查和血液生化指标检查的方法对该牛进行诊断。结果表明:患牛白细胞数、淋巴细胞数、单核细胞数、中性粒细胞数均高于参考值;红细胞数、血红蛋白浓度、血细胞比容、血小板数均低于参考值,说明该牛有严重的贫血和感染。另外,该牛肌酐、尿素浓度高于参考值,提示该牛肾脏功能衰竭。检查后第2天该牛死亡,为查明患牛死亡原因,对死亡牛进行病理剖检和病理组织学检查,发现该牛有关节纤维毛细血管瘤、膀胱炎性渗出和肾脏萎缩。关节纤维毛细血管瘤在本病例中出现较晚,且毛细血管瘤是一种较为常见的良性肿瘤,据此推断关节纤维毛细血管瘤不是该牛只死亡的原因,主要原因是膀胱炎和肾脏功能衰竭。

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.
