Kidney pressure. Symptoms and clinical course of the disease

Kidney pressure, the symptoms of which are composed of many factors, is inherently an arterial hypertension caused by diseases of the renal parenchyma or kidney vessels. About 30-35% of people suffering from hypertension have concomitant diseases of the kidneys, because of which there is a steady increase in pressure, because pressure and kidneys are often interrelated.

Nephrogenic hypertension is divided into two types: vasorenal and parenchymal and both affect the renal pressure. Symptoms can be very blurred and often mistaken for other diseases. Vasorenal hypertension develops due to unilateral or bilateral stenosis or occlusion of the renal artery, as well as its branches. Vasorenal hypertension can be both acquired and innate. Parenchymal hypertension, in the vast majority of cases, is due to bilateral chronic pyelonephritis or other kidney diseases, for example: nephrolithiasis (kidney stones), tuberculosis, tumor processes, cysts, hydronephrosis, polycystosis and a number of other diseases.

On average, vasorenal hypertension occurs in 5-12% of individuals suffering from hypertension. There are several basic congenital causes of vasorenal hypertension, which include: aneurysm, dysplasia and other pathological abnormalities of the development of the renal arteries, arteriovenous fistula. Among the causes characteristic of the acquired form of vasorenal hypertension can be identified: stenosis of the renal artery in the aftermath of atherosclerosis, changes in the renal arteries due to progressive nephroptosis, embolism or thrombosis of the renal arteries or their branches, panarteritis, compression of the arteries of the kidney from the outside (tumors, cysts, Etc.).

Symptoms and clinical manifestations of vasorenal hypertension

Vasorenal hypertension takes place among all age categories, but most often occurs in people under 50 (93% of all cases). The most frequent lesion of the renal artery is atherosclerotic sclerosis. This type of pathology, mainly found among males aged 35 to 40 years. In women, the main etiological factor in the development of the disease is fibromuscular stenosis of the renal arteries and is found among young girls.

Kidney pressure, the symptoms of which are characterized by sudden onset and rapid (often malignant, in 18-30% of cases) course. Hypertension is accompanied by a very high level of diastolic pressure (110-125 mm Hg and more); Rarely there is a crisis. Recognized as a vasorenal hypertension more often by accident.

Diagnostics

To recognize the presence of vasorenal hypertension, you should conduct three stages of the study. The first stage determines the need for aortography. For this purpose a detailed anamnesis is collected, other general clinical methods of investigation are used. In the anamnesis there is often a lack of a hereditary nature of the disease, the appearance of hypertension after pain in the lumbar region. Renal pressure, the symptoms of which are always blurred, is very difficult to diagnose and requires immediate medical attention at the first manifestations.

The second stage includes conducting aortography and arteriography of the kidneys and, if any changes in the kidneys are detected, blood from the renal veins is collected. Blood is studied for activity in plasma renin in the next stage of diagnosis.

The final stage of the examination is an attempt to establish the dependence of arterial hypertension on the revealed pathological changes in the renal artery system. To prove this point of view, the methods of isotope renography, erection of urography and the study of renin activity are applied. In 8-10% of cases, patients develop a powerful collateral circulation, which compensates for functional disorders of the affected kidney.

Treatment

Renal pressure, whose folk remedies can only lead to the development of serious complications, must be corrected with the help of an operative intervention, whose goal is to restore the main circulation of the renal arteries.
