Renal hypertension symptoms and treatment. Renal hypertension is a secondary hypertension, mainly due to renal parenchymal lesions and renal artery disease caused by elevated blood pressure. The incidence of the disease is mainly due to glomerular degeneration, interstitial tissue and connective tissue hyperplasia, tubular atrophy, renal small artery stenosis, resulting in both the substantive damage to the kidneys, but also the lack of blood supply; renal artery wall Middle mucus muscle fiber hyperplasia, the formation of the majority of small aneurysms, so that the renal artery wall was beaded beads prominent, resulting in segmental stenosis of the renal artery; non-specific Takayasu arteritis, causing renal perfusion insufficiency; in the combined effect of the above factors , Leading to the occurrence of hypertension. And high blood pressure will cause kidney damage, the two promote each other, will make the disease further development, therefore, for renal hypertension to active treatment.

Renal hypertension symptoms in clinical

1. Signs about half of the upper abdomen, ipsilateral lower back or rib margin, hear a continuous systolic murmur, or with mild tremor.

2. Renal hypertension symptoms 30 years old or 50 years old, long-term high blood pressure suddenly increased or sudden onset of hypertension, short duration, rapid progress, diastolic blood pressure is particularly evident, with lower back or rib abdominal pain, drug treatment is invalid.

3. Special inspection The following can be done separately or in combination:

  • A.Renal angiography, showing arterial filling defects, stenosis of the distal vasodilatation or no vascular parts;
  • B.Intravenous pyelography, showing kidney kidney 1.5 ~ 2.0cm smaller than the kidney, irregular shape, early development slow and pale, late development thicker;
  • C. Percutaneous puncture with the catheter inserted into the inferior vena cava, respectively, to take both sides of the renal vein blood for renal determination, suffering from renal vein blood renin higher;
  • D. Sub-renal function determination, showing a small amount of kidney urine, urinary sodium low, creatinine or inulin clearance rate decreased;
  • E. Ultrasound showed less kidney.
  • F. Kidney chart showed ipsilateral curve of the vascular segment is low and delayed, excretion section extended.

Renal hypertension treatment need to accord to the renal hypertension symptoms

1, renal vascular hypertension treatment:

renal vascular hypertension treatment, mainly to surgery, including nephrectomy, renal vascular reconstruction, percutaneous transluminal renal artery angioplasty (PTRA), renal artery stenting ( Metal stent) and other interventional therapy. Drugs preferred calcium channel blockers, such as felodipine, nifedipine, etc., can effectively reduce blood pressure, less cause kidney damage. Followed by beta receptor antagonists, such as metoprolol. Angiotensin converting enzyme inhibitors (ACEI) and angiotensin II (Ang II) receptor antagonists are contraindicated in the treatment of renal vascular hypertension.

2, the treatment of renal parenchymal hypertension

Drug treatment: to block the renin - angiotensin system (RAS) as the preferred method. There are currently two categories of blocking RAS drugs currently used: ACEI and Ang II receptor antagonists. Medication should in principle avoid kidney damage drugs, low dose start, combined medication. Other include diuretics, calcium antagonists (CCB), alpha, beta blockers and the like.

More and more patients with high blood pressure. Diet structure is irrational, intake of cholesterol is too high, a lot of alcohol, lack of sleep, lack of exercise, etc., are the reasons for the rise in hypertensive patients year after year.There are many renal hypertension symptoms,patient should promote healthy lifestyles, eliminate behaviors and habits that are detrimental to mental and physical health, and reduce the risk of high blood pressure and other cardiovascular disease. Adjust the living habits, quit smoking, control drinking, the right to deal with environmental stress, to maintain a normal state of mind. For end-stage renal failure in patients with dialysis, first of all to adjust the water and salt intake, to achieve the ideal dry weight. Note that low sodium, low fat. Low sodium can not only effectively control the sodium, water retention, and can increase ACEI and calcium channel blockers (CCB) of the antihypertensive effect.

Especially in the season when the replacement, it is necessary to pay close attention to blood pressure, keep blood pressure stability. Also note that high blood pressure patients must adhere to taking antihypertensive drugs, can not be random withdrawal. Even if not feel uncomfortable, should also adhere to medication. Otherwise, it is very dangerous, random withdrawal and other high blood pressure after eating it is easy to cause blood pressure rebound. In the process of bounce, some of the organs of the body will be unknowingly hurt, and may even appear cardiovascular and cerebrovascular accident. We recommend that when the blood pressure dropped to the normal range, you can appropriately reduce the dose, but can not just stop. In addition to persist in taking medicine, the regular review is also very important, especially for blood pressure observation, we recommend the best patients at home to prepare blood pressure meter, regular monitoring of blood pressure.
