What is hypertensive nephropathy caused by

summary

Hypertensive nephropathy is prone to various complications, my second uncle at that time appeared hydronephrosis, using a lot of methods for treatment, then gradually stabilized. Let's take a look at what causes hypertensive nephropathy.

What is hypertensive nephropathy caused by

First, the kidney itself is used to filter toxins in the body, excrete excess water and sodium salt through urine, and prevent protein, blood cells and other leakage of blood vessels. High blood pressure increases the blood pressure in the blood vessels, leading to the leakage of protein into the urine. Once the protein leaks out, it will damage the filter system of the kidney.

Second, if the hypertension is not well controlled for a long time, the structural damage is difficult to reverse, and the renal function will be damaged gradually, even chronic renal failure, and the final serious stage is uremia.

Third: renal vascular disease: narrow renal artery or its branches caused by various causes, atherosclerosis and muscle fiber hyperplasia are the most common, non-specific arteritis and transplant exclusion fibrosis can cause renal artery ischemia, thrombosis or embolism, which can cause renal hypertension.

matters needing attention

Hypertension can directly cause kidney damage, namely the so-called hypertensive nephropathy, including benign renal arteriosclerosis and malignant renal arteriosclerosis. Benign renal arteriosclerosis is a kind of hyaline degeneration of renal arterioles caused by long-term hypertension, which leads to renal ischemia, hypoxia, fibrosis, sclerosis, necrosis, and then renal insufficiency, which will eventually develop to uremia.
