Shijiazhuang Kidney Disease Hospital introduce it from summary, causes and the difference from renal hypertensive, and hope it is helpful to all readers.
Hypertensive Nephropathy Summary:
Hypertensive nephropathy refers to renal failure caused by long term
hypertention and is called Nephrosclerosis on diagnosis. It is common in elder
hypertention patients whose urine protein in 24h is less than 1g and without
other renal pathological changes. Hypertention is known to induce kidney
disease, and vice versa. In addition most renal failure patients not undergo
renal biopsy, so the rate of Nephrosclerosis is possible highly estimated.
Cause of hypertensive nephropathy
Renal blood flow volume takes up about 1/5-1/4 of cardiac output, and kidney
is composed of numerous microvascular plexus, so high blood pressure will damage
kidney without doubt. Long-term hypertention will induce block and
atherosclerosis in arteries. If the pathological change is in renal arteries,
renal infarct may occur, and there will be symptoms like urine protein and high
Since hypertention and renal injury affect each other, they will aggravate
the disease together.
Is hypertensive nephropathy the same as renal hypertention?
There is no obvious functional or structural change in the early stage of
Long time high blood pressure can lead to less blood flow in the kidney, thus
causing renal arteriosclerosis. Day by day, renal function will be damaged. The
kidney may even shrink. At the early stage of hypensive nephripathy, patients
can have high blood pressure or have no high blood pressure. With time passing
by, water and sodium will accumulate into the body, and influence the balance of
endocrine hormone. High blood pressure can lead to damage in the kidney, leading
to hypensive nephripathy. And hypensive nephripathy will in turn lead to further
or higher blood pressure. they interact each other in other words. So at the
early stage of high blood pressure, people should control their high blood
pressure and stop it worsing or leading to further damage.
