Thus, by the experimental production of lesions similar to those observed at autopsy, the reproduction of clinical symptoms, thought to be the result of organic changes, is often attempted. This study aimed to investigate renal outcomes and their predictors in biopsy-proven hypertensive nephrosclerosis (HN) patients and to compare clinico-pathological characteristics and prognoses between benign nephrosclerosis (BN) and malignant nephrosclerosis (MN) patients. Its pathogenesis is multifactorial.

Malignant nephrosclerosis in patients with hemolytic uremic syndrome (primary malignant nephrosclerosis). Nephrosclerosis (NS) is an example of the visceral complications seen with the hypertensive patient. Malignant hypertension in blacks. Vascular changes in benign HTN are evident and depend on the vessel size. Smaller renal vessels such as arterioles display fibrinoid necrosis and inflammatory cells may be present, yielding a picture of "Necrotizing Arteriolitis".

Benign nephrosclerosis , Malignant nephrosclerosis Thrombotic microangiopathies. Cryoglobulinemic glomerulonephritis was found in two-thirds of the patients (66.6%) and hypertensive nephrosclerosis in one (33.3%). It should be distinguished from renovascular hypertension, which is a form of secondary hypertension, and thus has opposite direction of causation. Fogo A, Breyer JA, Smith MC, et al.
