Abstract:
During present investigation, total number of 586 kidney of pigs were examined macroscopically. Out of which, total 154 specimens of kidneys showing macroscopic lesions were processed for further histopathological examination. Histopathological examination revealed pyelonephritis 0.65 per cent specimens. Grossly, the kidneys were enlarged and congested and presence of small and large greyish white nodules on the surface of the kidneys along with the capsule could be stripped off easily. Renal calyces were dilated with red, ulcerated wall and filled with a greasy purulent mass. The renal papilla showed hyperaemia and cortical haemorrhages. Microscopically, the cavity of Bowman’s capsule, glomerular tuft and surrounding tissues showed infiltration of neutrophils. Glomerular loops were also filled with polymorphonuclear cells and few mononuclear cells. There was marked cellular infiltration in the renal tubules and interstitial connective tissue and tubular epithelial cells necrosis was also seen. Looking to the immediate need of understanding the various pathological conditions involved in urinary diseases and for providing timely diagnosis.
