Renal arteriosclerosis

Introduction Renal arteriosclerosis refers to a type of disease that affects renal vascular function due to the renal artery and branches and/or arterioles. According to the progress of the disease, it is divided into benign small arteriosclerosis and malignant small arteriosclerosis.

Cause

The main cause of benign small arteriosclerosis is hypertension and old age. Kidney arteriosclerosis due to prolonged hypertension.

About 40% of the underlying diseases of malignant small arteriosclerosis are hypertension, 15% are chronic nephritis, and the rest are multiple nodular arteritis, radiation nephritis, congenital kidney disease, renal pelvic fluid, Cushing's syndrome. .

an examination:

1. Patients over the age of 50 or long-term hypertension are not well controlled, and hypertension is moderately above.

2. Mild proteinuria, with renal tubular dysfunction.

3. With heart, cerebral arteriosclerosis and fundus changes.

4. Exclude high blood pressure caused by other kidney diseases such as chronic nephritis.

Differential diagnosis

Differential diagnosis

1. Renal vascular hypertension: manifested as hypertension. However, it is more common in young people. In the past, the blood pressure was normal; the upper abdomen could smell vascular murmur; the length of the long axis of the two urinary tract angiography was 1.5 cm or more; the renal artery angiography showed the stenosis of the renal artery and the expansion after stenosis;

2. Chronic pyelonephritis: manifested as chronic progressive hypertension and renal reduction. However, in the past, there was a history of urinary tract infections, urinary system symptoms and urinary changes occurred before the occurrence of hypertension; the number of pus cells in the urine was high, and common bacteria cultured had pathogenic bacteria.

diagnosis

1. Often moderate to high blood pressure and its clinical symptoms.

2. May be associated with heart, brain, fundus arteriosclerosis and its performance.

3. There is mild proteinuria, the degree of which is positively correlated with hypertension.

4. There may be nocturia in the later stage, and the urine specific gravity and urine permeability will decrease, resulting in renal insufficiency.
