Hypertensive nephropathy of primary hypertension caused by benign arteriolar
nephrosclerosis (also known as hypertension, renal arteriosclerosis) and
malignant arteriolar nephrosclerosis accompanied by corresponding clinical
manifestations of the disease, hypertension and renal failure.
Many perennial history of hypertension, renal tubular damage is how early in
the glomerular nocturia, urinary concentration dysfunction, urine change to
lighter, mild proteinuria, microscopic hematuria and tubular, often other target
organ complications of hypertension.
Hypertensive nephropathy medical examination found that: said the general
blood pressure increased persistent (/ Kpa / mmHg or more); some of the eyelids
and / or lower extremity edema, heart border to expand; majority of
arteriosclerotic retinopathy, when retinal stripe flame-shaped hemorrhage and
cotton wool soft exudate in support of the malignant renal atherosclerosis,
diagnosis with hypertensive encephalopathy can locate signs of nervous
system.
The kidney itself is a large blood, used to filter toxins from the body,
while preventing the leakage of blood vessels of protein, blood cells and other
substances. High blood pressure makes the increased intravascular blood pressure
can make the protein leakage, protein leakage would be the kidney's filter
system to cause damage to a vicious cycle. Time long-term damage caused is
difficult to reverse kidney compensatory increase until failure in advance. This
is why there is hematuria terrible, terrible proteinuria. The common causes are:
the incidence of hypertensive renal damage was positively correlated with the
severity of hypertension and duration. Other possible factors, including gender,
race, diabetes, hyperlipidemia, and hyperuricemia, and these factors influence
each other, and further aggravate kidney damage. Men than women more susceptible
to kidney damage. The age of onset of essential hypertension is generally 25 -
45 years old, and hypertension-induced kidney damage to the age of onset of
clinical symptoms generally 40 - 60 years old. The earliest symptoms of nocturia
increased, reflecting the the tubular already ischemic lesions in urine
concentration function began to subside. And proteinuria, indicating that the
glomerular lesions. The degree of proteinuria is generally mild to moderate
(or), 24-hour urinary protein excretion is generally not more than 2 g, but a
small number of patients with massive proteinuria. Urine sediment microscopic
examination of red blood cells and tube small, individual patients due to
glomerular capillary rupture transient gross hematuria. Research has shown that
one ten thousandth of the development of renal failure in patients with
essential hypertension, untreated hypertension in patients with reduced renal
function than those without high blood pressure is obvious.
Often can be found in other organs caused by essential hypertension,
cardiovascular complications, these complications may appear earlier than kidney
damage, the condition is more serious, as the main or key factors influencing
the prognosis. The most common cardiac complications of hypertensive left
ventricular hypertrophy, and easy to heart failure, angina pectoris;
cerebrovascular complications of cerebral hemorrhage and cerebral infarction of
cerebral vascular accident in essential hypertension cause of death ranking the
first place. Essential hypertension can also cause retinal arteriosclerosis,
further cause arteriosclerotic retinopathy. The degree of retinal
arteriosclerosis and blood pressure is proportional to, where and diastolic
blood pressure more closely. Retinal sclerosis is generally parallel with renal
atherosclerosis can be broadly reflect the renal artery, it is very important to
fundus examination.
