What symptom does renal artery stenosis have

summary

Renal artery stenosis often appears in our life. What kind of early manifestations does renal artery stenosis have? Then there are many reasons for this disease. No matter what kind of disease it is, it needs to be treated in time. In fact, for this kind of disease, what kind of clinical symptoms does the body have? In fact, for renal artery stenosis, the onset of the disease is very important People and the signs of the disease also need to pay attention to, below we need to pay attention to the performance of renal artery stenosis? 　　

What symptom does renal artery stenosis have

First, renovascular hypertension is characterized by rapid development of hypertension and obvious increase of diastolic blood pressure (often more than 110-120mmhg), which can be manifested as malignant hypertension. Sometimes, vascular murmurs (high tone, rough systolic or biphasic murmurs) can be heard in the abdomen (or waist). The kidney of the affected side was reduced by B-ultrasound (the difference between the length and diameter of the two kidneys was more than 1.5cm). About 15% of the patients developed hypokalemia due to increased plasma aldosterone. The patient's urine routine changed slightly (mild proteinuria, a small amount of red blood cells and tube type). When the contralateral kidney is damaged by hypertension in the late stage of unilateral renal artery stenosis, or when the bilateral renal artery stenosis progresses. Renal function will gradually decline.

Second, ischemic nephropathy is common in the elderly with multi site atherosclerosis, with or without hypertension. The main manifestations of renal lesions were progressive renal dysfunction (early damage of renal tubular function, nocturia, decrease of urine specific gravity and osmotic pressure; then glomerular dysfunction, decrease of endogenous creatinine clearance rate and increase of serum creatinine), mild abnormal urine (mild albuminuria, a small amount of red blood cells and tubular type) and gradual reduction of renal volume (the size of two kidneys is often asymmetric).

Third: kidney disease can have varying degrees of proteinuria. Chronic renal insufficiency gradually appears after long-term chronic renal ischemia. A few patients may have low back pain, nausea, vomiting, fever, proteinuria, hematuria and other segmental renal infarction.

matters needing attention
