Glomerular nephritis

Kidney

Because the kidney plays a very important role in the regulation of blood pressure, some diseases of the kidney can lead to hypertension. In fact, 3% of the 4% hypertension is associated with kidney, especially in young patients and those with diabetes. The urine is often used for the diagnosis of kidney disease caused by hypertension.
Renal vascular hypertension
Renal vascular hypertension is the most common secondary hypertension. Renal vascular hypertension occurs when most of the arteries (kidneys) are supplied to the kidney (more than half) or completely blocked. If the blood supply to the kidney is reduced, it is affected by the release of the renin to respond to the kidney. Renin is not only an elevated blood pressure in the renal arteries, but rather an elevated blood pressure in the whole body.
In most people with renal vascular hypertension, the arteries are clogged with plaques. In some cases, the renal arteries can be completely removed by surgery, and it can also be removed by vascular reconstruction. Once the artery is open, blood pressure will return to normal. Renal vascular hypertension patients for the elderly (over 55 years of age), and systolic blood pressure tends to be higher. Other arteries in the body, such as the coronary artery, are prone to clogging.
Fibromuscular hyperplasia
Renovascular hypertension can also be caused by fibromuscular hyperplasia. In this patient, the muscular and fibrous tissue of the renal arteries (arteries) in the renal arteries increases and becomes ring. Like common atherosclerotic plaques, these fibrous tissue rings interfere with the flow of blood in the renal arteries. Fibromuscular hyperplasia occurs mainly in young white women (usually less than 30 years old), and when they get pregnant, is likely to get worse. Can be used for dredging or widening reconstruction of renal artery by surgical operation, so that the blood pressure returned to normal.
Glomerular nephritis
The kidney is responsible for removing the body’s waste products and excess sodium and other substances. Small filter material in the kidney is called the glomerular. Glomerulonephritis is the inflammation of these filters. Inflammation of the kidney can not play a role, and may eventually become permanent damage and make functional recession T results is a significant rise in blood pressure. If the glomerular nephritis is a sudden attack, such as a result of infectious diseases, urine will be black (usually with blood), and a sharp rise in blood pressure can cause headaches and vision problems. Acute (sudden) episodes of glomerulonephritis in children and young people. Chronic glomerulonephritis is gradually developing, and will continue for many years. Unless the kidney is seriously hurt by the disease, the symptoms of chronic glomerulonephritis are not very obvious. According to the disease and the disease, a lot of mild acute glomerulonephritis may be better. If it is an acute attack, the first need to treat the underlying cause of disease.
Polycystic kidney disease
Polycystic kidney disease is a genetic disease, patients with two kidneys have a lot of cyst (charge to shout Zhu Zhu Xia Han Bu production bases rare into kidney volume increased and functional decline. In the body such as a cyst in pregnancy can be detected by B ultrasound or genetic examination, otherwise the disease will not occur until the time of childhood multiple urinary tract infection and hematuria, etc.. This kind of cyst can destroy normal kidney function, cause uric road infection and high blood pressure, both of them should be treated, if need, still need to take medicaments appropriately. Polycystic kidney disease can only be treated by renal transplantation.
Kidney water
When a part of the kidney is inflamed and the urethra is blocked, it will occur. The acute attack of the kidney or the slow production, or in the middle of the kidney may occur in the middle of the kidney, the kidney may be due to congenital (born when there is) the cause of urinary tract obstruction. Because of its damage to kidney tissue can cause blood pressure rise, must rely on surgery to remove excess water wells to solve the problem of blockage. Once the renal function returned to normal, blood pressure will generally return to normal levels.
