Abnormal glomerular function may lead to damage of glomerulus components such as capillary endothelium, mesangium and epithelial basement membrane. In renal biopsy we can see cellular and structural pattern of glomeruli injury by using electron microscopy. As per the time of examination and the intensity of the lesions, in vascular diseases and glomerular ones we can identify tubular damage in glomerulus, interstitial inflammation, tubular atrophy, fibrosis or edema. Tubular or acute interstitial damage may lead to acute kidney failure, and prolonged changes are a best investigation parameter for irreversible lesions and then they are great anticipatory variables in vascular /glomerular diseases.

This session includes Glomerulonephritis, Glomerulopathy, Acute Pyelonephritis, Chronic Pyelonephritis, Acute Infectious Tubulointerstitial Nephritis (Tin), Tin Associated with Systemic Infection, Chronic Infectious Tin (Chronic Pyelonephritis) and Specific Renal Infections Xanthogranulomatous Pyelonephritis, Acute Interstitial Nephritis Associated to Drugs, Acute Tubular Necrosis and Other Tubular Changes.
