Hypertension and kidney can be traced between them a mutual relationship: due to the increase in pressure disturbed function of the kidneys and, on the other hand, the pathology of this body leads to hypertension.

Hypertension — most common cardiovascular disease. According to statistics, 10% of patients diagnosed with renal hypertension, which is caused by diseases of the organ responsible for filtering blood and removing fluid. Similar condition not easy to diagnose, severe in 25% of cases and causes serious consequences. Therefore we should look closer at the specifics of the disease, especially its recognition and treatment.

What is renal hypertension?

This increase in pressure due to violations of the kidneys and, consequently, disrupt the function of regulation of blood circulation. This is also called secondary hypertension because the increase in pressure in this case is a symptom of another disease, and not an independent process, which is typical for the diagnosis of hypertension.

Most often suffer from this ailment the elderly and young men due to the greater body mass and, consequently, a larger volume of the vascular bed. In case of resumption of renal function, BP comes to normal.

Varieties of the disease

Renal form of hypertension is divided into 3 groups:

  • Rinofaringitis disease with involvement of the shell that regulates the flow of liquid. The consequence of lesions of the parenchyma are swelling, protein in the blood, the urine due to the inverse of the blood outflow. This includes diabetes, kidney stones, pyelonephritis, glomerulonephritis, systemic diseases (such as lupus erythematosus, scleroderma), congenital defects of the structure, the renal tuberculosis.

  • Renovascular pathology is characterized by narrowing of the lumen of one or more vessels by 75%. It is less common, but leads to a more severe course. The reasons for these disorders: atherosclerosis (especially in the elderly), constriction of blood vessels (hematoma, cyst), the anomaly of their development. In the treatment of this group of diseases anti-hypertensive medications ineffective.
  • Combined syndrome of hypertension are caused by damage of the parenchyma, and vessels. Similar changes can occur with kidney disease: nephroptosis, tumors, cysts.

Causes and pathogenesis

Hypertension eventually worsens the condition of the kidneyand various kidney diseases can cause of high blood pressure.

Hypertension and kidney can be traced between them a mutual relationship: due to the increase in pressure disturbed function of the kidneys and, on the other hand, the pathology of this body leads to hypertension.

Renal hypertension is called 3 mechanisms:

  • The increased blood flow leads to disruption of the filtration, the accumulation of water and sodium ions. Because of this active hormone promoting absorption of sodium, causing hypertonicity of the blood vessels due to swelling of their walls. That is, the pressure rises because of the increased amount of fluid outside cells and edema of the walls of the arteries.
  • Due to kidney failure, is allocated a number of biologically active substances: renin is secreted in greater volume due to narrowing of the blood vessels and, by interacting with the protein to form angiotensin-II. It itself increases the tone of blood vessels and also increases the production of aldosterone, which enhances the absorption of sodium and thus exacerbates swelling of the arteries.
  • Suffering depressor function of the on — reserve of hormones that reduce blood pressure by excretion of sodium from the muscle vessels over time, is depleted and a stable high pressure is becoming the norm.

The reason for the increase in pressure associated with the kidneys, are related to the types of the described pathology that presented in the table:

 

Symptoms and specificity of current

As with hypertension, the patients have difficult breathing, weakness, dizziness, headache, tachycardia, a rise in pressure. However, kidney disease for hypertension causes edema, pain in lumbar region, increased frequency and volume of urination.

If the disease is benign, the symptoms are slowly growing, raising blood pressure stable, possible anxiety and irritability, discomfort in the heart area.

A malignant course characterized by rapid development, vision disorders, nausea and vomiting, the minimum difference between the upper and lower pressure, a strong headache. Subsequently, the clinical picture can join such complications as heart and kidney failure, disorder of lipid metabolism, blindness, cerebrovascular accident.

The correct diagnosis

Such patients examined by a physician, and then prescribes treatment. First and foremost, reveal the pressure change when you perform certain exercise and change body position.

Then take the blood and urine tests, determining the presence of protein. Sometimes in search of an enzyme take blood directly from the veins of the kidneys. Using the phonendoscope auscultated systolic murmur in the umbilical region. Thanks to ultrasound and MRI it is possible to study the structure of the kidney, search formations.

Also used in the diagnosis of excretory urography to study the urinary tract. Angiography and fundus examination allow to identify changes of blood vessels, and radioisotope rheography shows degree of dysfunction. If the doctor suspects cancer, a biopsy with further cytological examination.

Therapeutic measures

  • Medication pathology

Treatment of renal hypertension is performed by the cardiologists in conjunction with nephrologists. Therapy begins with diet No. 7. Sometimes when a transient pressure increase, this is enough. In case of poor tolerability of the dietary table or a minor improvement, add medications called loop diuretics.

In renal insufficiency, the degree of impairment of the function calculated on the basis of glomerular filtration, which subsequently is taken into account during the selection of medicines. Drugs used to normalize blood pressure — thiazide diuretics and blockers. Some antihypertensive drugs improve kidney function.

  • Non-drug treatment

If the drugs do not have the expected effect, is balloon angioplasty or surgery. The first method is indicated in stenosis and involves the insertion of a cylinder, which subsequently holds the vascular wall, reducing pressure. Surgically treated renal hypertension trying in the case of congenital defects, stenosis or overlap of vessels, the lack of success of previous therapy. The options of surgery are resection of the artery and endarterectomy to restore patency, removal of the kidney in case of significant lesion.

Also used tonirovanie or exposure to acoustic waves, which destroy platelets. In fact, this micro-massage at the cellular level. The method restores the functioning of the kidneys, increases the content in the allocated urine uric acid the body, stabilizes blood pressure. In the terminal stage of use of the hemodialysis of the kidney in combination with drugs that reduce blood pressure. Treatment of hypertension carried out in parallel with treatment of the underlying disease.

Prevention of hypertension in kidney disease

Renal hypertension requires daily monitoring of blood pressure, should not be allowed as its increase and decrease. If you feel unwell, you should immediately consult a doctor.

You need to limit foods that contain sodium, such as seafood, hard cheese varieties, sea Kale, and to replace animal proteins in the plant, to limit salt intake. The diet should include fish oil, onions, garlic.

Important modification of lifestylethat includes exercise therapy, Smoking cessation, and alcoholic beverages, as they adversely affect the kidneys and contribute to high blood pressure.published econet.ru.
