High blood pressure, Hypertension as a more formal name, is a very common
complication of Chronic Kidney Disease (CKD), and many people wonder what is
primary Hypertension or secondary Hypertension. Some may have certain knowledge
that there is relation between high blood pressure and kidney disease. Then,
what are Hypertensive Nephropathy and Renal Hypertension?
Hypertension is a general disease which is characterized by the rising
arterial blood pressure accompanied with organic lesions of heart, blood
vessels, brain or kidney. It can be categorized into primary one and secondary
one. High blood pressure is a quite common cardiovascular disease, and when the
secondary one, when the primary disease remits, the blood pressure will become
normal gradually.
Hypertensive Nephropathy refers to kidney lesions that are caused by
long-term Hypertension. Long-term high blood pressure make the pressure in
glomeruli rises as well. Meanwhile, glomeruli become fibrosed and atrophied, and
renal arteries sclerosed. Since there is shortage of blood in renal parenchyma disease,
nephrons become less and less, and Kidney Failure appears finally. Under general
circumstance, proteinuria and hematuria will not appear with primary
hypertension, and the decline of kidney function begin with the damage on renal
tubules and their function of concentration, so the filtration function can
still be normal for a long time. However, at last, glomerular filtration rate
drops and serum creatinine rises to be higher than the normal value.
Renal Hypertension is a kind of Hypertension which is aroused by kidney
disorders, so it is a secondary Hypertension. It can be categorized into two
type, one is renal parenchyma disease Hypertension, another is Renovascular
Hypertension. Renal Parenchymal Hypertension comes from the loss of massive
nephrons which leads to the retention of water and sodium, activating the RAAS
syImmunotherapy, and making blood pressure rise thereby. At the meanwhile, high
blood pressure can lead to the further deterioration of kidney disease, forming
a vicious circle. Renovascular Hypertension is a kind of hypertension which is
caused by the stenosis of unilateral or bilateral renal arteries. Kidney lacks
blood and RAAS syImmunotherapy begins to work, so blood pressure becomes higher.
When Renal Hypertension is detected, kidney diseases can also be found at the
same time. Proteinuria, hematuria and Anemia are always showing up as an
accompanying manifestations. Also, glomerular filtration rate declines, and
creatinine clearance rate declines.
