Determine how hypertensive renal damage?

Essential hypertension and renal damage caused by the severity of the hypertension, duration is closely related to clinical manifestations of essential hypertension renal damage mainly benign renal atherosclerosis. Small benign renal hypertension and the occurrence of atherosclerosis extent and duration were positively correlated. General essential hypertension last five to 10 years, there will be light to moderate renal atherosclerosis, a progressive renal tubular and functional changes. Clinical diagnosis of hypertension small benign renal artery hardening mainly based on: ① there is a genuine and continuing history of hypertension; ② the age of onset of hypertension in the 25-year-old to 45 years old, in the course of more than 10 years, the greater the incidence of the higher age; ③ with hypertension other organ damage such as: left ventricular hypertrophy, fundus vascular diseases; ④ outstanding clinical performance for tubulointerstitial damage, such as increased nocturnal enuresis, urinary concentration dysfunction, and some patients may be in for proteinuria and a small amount of red blood cells, a small number of performance elevated serum creatinine; ⑤ kidney B - inspection, kidney or two narrow renal size, granular surface was uneven; ⑥ exclude primary kidney disease patients with hypertension; ⑦ renal biopsy showed arteriosclerosis mainly to the pathological changes. Essential hypertension caused kidney damage, usually before a urine test in accordance with clinical abnormalities, and then there hypertension, it is necessary to consider the primary kidney disease associated with hypertension; if there hypertension after the first recurrence of abnormal urine test to hypertension kidney disease caused by the possibility of damage.
