Hypertensive Nephropathy is caused by?

Hypertensive renal disease is how is it?
[A] benign hypertension with mild hypertension does not lead to renal dysfunction, moderate to severe hypertension can cause renal dysfunction, but is less severe renal dysfunction. Small renal arteries of these patients have disease, glomerular and tubular damage, kidney slightly smaller, cortical thinning, surface irregular granules, called benign glomerular Benign hypertensive renal disease manifestations:
[1] related to the level of proteinuria and hematuria, and hypertension.
[2] urinary sodium excretion, due to increased renal vascular pressure affect the renal tubular function.
[3] azotemia and uremia. Treatment: the need for long-term antihypertensive treatment to reduce proteinuria and renal function improved.
[Two] malignant hypertension renal afferent arterioles and capillary plexus extensive fibrinous necrosis of the basic features of malignant hypertension. Wall thickening of small blood vessels, thereby increasing renal ischemia, renal impairment. Of the disease are associated with kidney damage, such as no effective treatment will rapidly to renal failure. Malignant hypertensive renal disease manifestations:
[1] proteinuria and hematuria, proteinuria serious than benign hypertension, gross hematuria.
[2] renal dysfunction: diastolic blood pressure over 130 mm Hg, and accompanied by 3 - 4 fundus changes in glomerular filtration rate fell by an average 28.6 percent annually, renal blood flow decreased by 38.6% annually. Treatment: untreated year of death, accounting for four-fifths of the patients died of uremia, cerebral hemorrhage, pulmonary edema. Effective antihypertensive therapy in renal function damage and stable renal function, or even apparent recovery, and reduce mortality. In uremia occurred, required dialysis. In short, regardless of the kind of situation, attention should be paid to the prevention of hypertension, aggressive treatment of high blood pressure, especially early in the discovery of high blood pressure, attention to be given treatment can prevent the formation of the consequences of hypertensive nephrosclerosis.
