Hypertension will cause kidney failure

15% of the high blood pressure will develop renal failure, and this is because the body of the urinary system is like one; wastewater excretory system, plays an important role in maintaining the machine physiological equilibrium process. The kidney is an important organ of the urinary system, it is like the central part of the water treatment system, the kidney is good or bad on the body is very important. Harm to the kidneys addition to allergic inflammation caused by bacterial infection, the more common clinical hypertension.
Under normal circumstances, hypertension involving the kidney is a relatively lengthy process. Pathological studies have shown that hypertensive kidney damage, mainly from the arterioles, no obvious early on renal morphology and function of the change. First, the renal artery hardening, stenosis, renal ischemic, some nephron fibrosis hyalinization, the normal nephron compensatory hypertrophy, with the continuous development of the disease, the surface of the kidney was granular, cortical thinning and shrinking due to the repeated destruction of the nephron, the kidney, and subsequent renal dysfunction and the development of uremia. However, due to the strong compensatory ability of the kidney to begin the only symptoms of renal dysfunction is nocturia increased. Urine routine examination, it may be seen under a microscope the red blood cells, of proteinuria and tube type.
Development decompensated renal insufficiency, concentrating ability of the kidneys to reduce the symptoms of polyuria, thirst, polydipsia, urine specific gravity lower and fixed around 1.010. When the further development of renal insufficiency, urine output decreased significantly, the blood of non-protein nitrogen, creatinine, urea nitrogen levels, edema, electrolyte imbalance and acid-base balance, X-ray or B ultrasound examination showed bilateral renal symmetrical mild narrowing. Selective renal arteriography may have varying degrees of renal artery stenosis.
