kidney Heart attack - a rather rare form of ischemic renal disease (a rare urological disease).The sudden and complete cessation of blood flow in the arteries are large enough, as a rule, it is the main cause of heart attack kidney.When

slowly increasing occlusion, as well as maintaining the partial flow may develop syndromes such as chronic renal failure progresses at different speeds, renovascular hypertension, and others.

Urine acid myocardial kidney

Urine acid renal infarction - a form of the disease, which is characterized by the formation of deposits in the kidneys of newborns urate crystals (ammonium and sodium) because, as a rule, birth stress.Gout, leukemia, and extensive suppurating tumor processes, characterized by a significant disintegration of tissue, often the cause of urate renal infarction in adults.

urate infarction kidney is ex

posed to about half of the infants at 2-5 days of life.Do not diagnosed kidney urate infarction in the newborn babies who died in the first days of life and stillbirths.

Among the main causes of heart attack kidney urate in newborns can distinguish hyaline protein substance that releases the epithelium of the urinary tubules of the kidneys of the child.Over time, the substance fills the lumen of the tubules, and then out of it formed hyaline cylinders, which are deposited uric acid salts.Increased secretion of urine provokes leaching of infarct mass in the bladder and in the renal pelvis.Inadequate child's body fluids, as well as insufficient dissolution of uric acid, wherein the concentration in the urine in the first days of a child's life is quite high, contribute to strengthening the process.

Urine acid renal infarction in the newborn is a physiological phenomenon, which does not need specialized treatment.Myocardial kidney in a newborn, it should be given plenty of drink that will enhance the level of their allocated urine.Thus, the symptoms of the disease gradually take place on 10-15 day of baby's life.

Causes In most cases, it is a ball, which is in the bloodstream, and then settled in the artery (embolus) becomes the main reason for the blockage of the renal artery.Embolus - a blood clot (thrombus) that usually occurs in the heart or in the aorta after breaking cholesterol plaque (atheroma).In some cases, a blood clot forms directly in the renal artery (acute form of thrombosis) due to damage to its walls.This fact can also be a cause of heart attack kidney.Renal artery wall damage may be the result of surgery, angioplasty and angiography.Formation of thrombi can occur against severe atherosclerosis, arteritis (inflammation of the arteries), the gap (protrusions) in the renal aneurysm wall, as well as sickle cell anemia.Blocking blood flow in an artery or a gap may be due to strain shell (acute bundle) of the renal artery.Among other causes of renal infarction can be identified atherosclerosis and fibromyshechnuyu dysplasia (abnormal growth of the connective tissue of the arterial wall).

In the treatment of kidney cancer, with a massive loss of protein in the urine (proteinuria), as well as heavy bleeding from the kidneys do not respond to treatment, renal infarction, in some cases, can be caused artificially (medical heart attack).At the same time spend a catheter into the artery supplying the kidney with blood, pre-blocking normal blood flow.

renal infarction symptoms

slight overlap of blood flow in the renal artery usually causes no pronounced renal infarction symptoms.In some cases, there may be a dull ache in the lower back in defeat.Among other symptoms of renal infarction can be identified nausea, vomiting, increased body temperature.Partial blockage of the artery can cause the development of the symptoms of heart attack kidney as high blood pressure.

Full stop urine and kidney function of education is a major symptom of heart attack kidney disease, which usually occurs when blockage of both renal arteries or one artery in patients with one kidney.

Diagnosis Diagnosis of heart attack kidney is based primarily on the results of blood and urine tests.In this case, it sets an increased number of blood leukocytes and protein in the urine indicated the presence of small amount of blood and particles.In some cases, you can visually set the urine stain with blood.

Diagnostics also is instrumental examination of the kidneys.This study is necessary because the symptoms and results of analyzes can not provide accurate information about the presence of disease in a patient.During the first two weeks after a large myocardial been a sharp decline in the affected kidney function.In determining the reduction of kidney functioning are directly involved radioisotope research and intravenous urography.In addition to heart attacks, kidney health reason for the decline may be other diseases.To determine the exact cause is used ultrasonography (US), and retrograde urography.

Arteriography of renal vessels - a procedure that allows the most accurate diagnosis and determine the nature of any violations.Arteriography of renal vessels is the introduction into the renal artery of a radiopaque substance.It should be noted that carrying out this procedure is possible only when the removal of obstacles in the bloodstream.

Intravenous urography and radioisotope study was repeated a month later to assess the pace of recovery of renal function.

renal infarction

Treatment If there is suspicion of renal infarction should promptly seek professional advice from a urologist or vascular surgeon.In some cases, the diagnosis of disease directly involved nephrologist.If you suspect a heart attack kidney needed urgent hospitalization.Patients with a heart attack, especially with hematuria, assigned bed rest.

Treatment of the disease when expressed pain is based on the use of painkillers.Narcotic analgesics are used with myocardial ischemic pain.In this situation, administered usually strong enough drugs.Hematuria is the basis for holding hemostatic therapy etamzilat sodium.Thrombolytics such as streptokinase are used in the absence of hematuria, and for a short time after the termination of blood flow.This therapy helps to restore kidney function, but even a slight hematuria is a serious contraindication to its implementation.

direct anticoagulants are used for correction of the blood coagulation system.The duration of treatment in this case is 8-10 days, after which the patient is transferred to oral medication.

In some cases a surgical removal of thrombus or embolus, then, should the need arise, angioplasty is performed.Surgery is effective in the short term, past after occlusion of the renal artery.
