To determine renal hypertension, clinical manifestations and laboratory tests, imaging tests and renal biopsy are mainly used to help determine, such as hypertension caused by renal disease can be called renal hypertension. 1. Clinical manifestations: renal hypertension may appear earlier with renal damage, manifested by hematuria, proteinuria and edema, which usually appear before or at the same time with hypertension. Renal vascular hypertension is usually manifested as malignant hypertension with headache, nausea, vomiting and blurred vision. 2. Laboratory examination: it mainly includes renal function, urine routine, blood routine, plasma renin angiotensin system examination, etc., which is helpful to determine whether the patient has proteinuria, hematuria and so on. 3. Imaging examination: color Doppler ultrasound renal blood flow imaging can be carried out to determine whether there is renal artery stenosis, such as abnormalities can also be carried out renal artery CT angiography and renal artery MR angiography. 4. Renal biopsy: renal hypertension is mainly characterized by glomerular vitreous degeneration, interstitial and connective tissue proliferation, tubular atrophy, etc., which can also help to determine. It is recommended that patients with hypertension should go to the hospital in time, complete the relevant examinations under the guidance of the doctor, clarify the cause of the disease, and take active treatment to avoid the development of the disease.
