Classification

Hypertensive nephropathy is classified according to disease severity and histological finding into two subtypes:

• Benign nephrosclerosis
  • It often occurs in the benign phase of essential hypertension.
  • It is characterized by Hyaline accumulation in the renal arterioles leading to afferent arteriolar narrowing.

• Malignant nephrosclerosis
  • It occurs in the malignant phase of essential hypertension, which is defined by a sudden elevation of blood pressure along with multi-organ damage such as papilledema, central nervous system involvement, cardiac decompensation, and progressive renal failure.
  • It is characterized by fibrinoid necrosis in the afferent arterioles.
