Renal hypertension – treatment of disease. Symptoms and prevention of diseases of the Renal hypertension

Renal hypertension – What is this disease? Renal hypertension is symptomatic (secondary) arterial hypertension, then there is the persistent increase in blood pressure levels, arising as a consequence of the defeat parenhima kidney or violations of trunk blood flow due to pathologies of the renal vessels.

The incidence of this pathology is about 7-10% among all the cases of arterial hypertension.

Renal hypertension – The cause of the

The reasons for the development of renal hypertension may be different. So, parenhimatoznaja arterial hypertension develops due to renal tissue lesion diffuse nature in such diseases as pyelonephritis, glomerulonephritis, gidronefroz, TB, multicystic kidney disease, nephropathy pregnant, amiloidoz, diabetic glomeruloskleroz, systemic connective tissue disease. Cause of renal vasorenal hypertension is hemodynamically significant stenosis (narrowing) Renal arteries, which develops as a consequence of atherosclerotic processes, nonspecific aorto-Arteritis, fibromyshechnoj dysplasia, mechanical compression of the renal vessels or their development anomalies. This leads to decreased blood supply to the kidney clubockov, that, in turn, contributes to the activation of the Renin-angiotensin-aldosterone system activity, which narrows the blood vessels through the release into the blood of vazopressonyh substances. Besides, gipoperfuzija kidney Medulla reduces activity kallickrein-kininova and prostaglandinovoj systems, that normally are responsible for pressure reduction. Thus, vicious circle, and hypertension quickly progresses.

Symptoms of renal hypertension

Clinical manifestations of renal hypertension depend on its form, nature of currents and associated diseases. When renal parenhimatoznoj hypertension, developed on the background of Glomerulonephritis, pyelonephritis, diabetes, etc.. typical symptoms of the underlying disease. This may be thirst, generalized weakness, increased urination, pain in the lumbar region, episodes raise body temperature, dysuria. Besides, common complaints in case of renal hypertension are headaches, dizziness, fatigue, breathlessness, palpitations, discomfort in the area of the heart, nausea. Patients can also observe increase of blood pressure numbers (especially diastolic) at independent its measurement. With malignant hypertension bystroprogressirujushhee notes during renal impairment, persistent intense headaches, nausea and vomiting.

Renal hypertension – Diagnostics

In the diagnosis of renal hypertension main criteria of diagnosis are increased blood pressure (diastolic increasingly) and the signs of defeat parenhima or vessels of the kidneys. To this end, the following research methods:

• General clinical blood analysis;
• biochemical blood analysis (determined by raising urea, creatinine, Uric acid, as well as glucose-diabetes);
• general urine analysis (changes in the density of urine, glycosuria-diabetes, leucocyturia, bacteriuria-when pyelonephritis, proteinuria and hematuria-when glomerulonefrite, etc.);
• sample Rehberg (evaluation of filtration of the kidney);
• study of Renin activity and aldosterone concentration in blood;
• Ultrasound of the kidneys;
• descending urography;
• dopplerograficheskoe study of renal artery, angiography (selective renal Arteriography, aortography);
• dynamic nefroscintigrafija;
• spiral computed, as well as magnetic resonance imaging;
• Kidney biopsy.

Renal hypertension – Classification

Depending on the causes there are three types of renal hypertension:

• renoparenhimatoznaja (in diffuse renal tissue lesions);
• renovascular (renovascular) -primary lesion of renal arteries;
• mixed renal hypertension (socetannoe defeat in tumors, nefroptoze, cysts, congenital anomalies of the kidneys).

According to the character of the flow of renal hypertension can be benign or malignant.

Renal hypertension – Actions of the patient

In the case of the previously described symptoms should consult a specialist.

Treatment of renal hypertension

Selection of therapeutic tactics in case of renal hypertension depends on the type and nature of currents. When renoparenhimatoznyh gipertenziah treatment is aimed primarily at the main disease therapy (pielo- or Glomerulonephritis, Diabetes, systemic diseases of connective tissue, etc.). When nefroptoze perform nefropeksiju, stenosis of the renal arteries-balloon angioplasty and stenting. Additional antihypertensive medicines (b-адреноблокаторы, ACE inhibitors, Calcium antagonists, etc.).

Renal hypertension – Complications

Most frequently in renal hypertension develop complications such as heart and kidney failure, retinopathy and hemorrhages in the retina, cerebrovascular accidents.

Prevention of renal hypertension

As the prevention of this disease it is recommended that timely diagnose and start treating other pathologies (endocrine, kidney, systemic diseases), and maintain a healthy lifestyle.
