The renal failure disease is likely to endanger the lives of patients, this disease is associated with shortness of breath is very painful, experts suggest the disease of renal failure, we must according to the type of disease in patients with symptomatic treatment. So what about the symptoms and classification of renal failure?
Classification of renal failure
Shock type acute renal failure: shock caused by various causes can cause acute renal failure. Common causes are bleeding, water electrolyte imbalance, cardiac circulatory failure, etc..
Two, infection type acute renal failure: bacteria, viruses, mold infection can be complicated by acute renal failure. The viral infection of predilection acute renal failure is viral pneumonia, encephalitis, hepatitis and epidemic hemorrhagic fever. Bacterial infection, especially gram negative infection, can cause acute renal failure.
Three, crush type acute renal failure: is due to serious crush injury caused by. Its pathogenic factors and clinical process are extremely complex. It is a common and important type in clinical practice.
Four, hemolytic type of acute renal failure: incompatible blood type transfusion, a large number of old blood transfusion, mechanical hemolysis can be complicated by acute renal failure. The main pathogenesis is disseminated intravascular coagulation.
Five, toxic acute renal failure: acute renal failure caused by many types of toxins, can be summarized into the following four categories: heavy metals such as mercury. Organic compounds such as DDT, dichlorvos etc.. Biological toxins such as venom and mushroom etc.. Nephrotoxic drugs such as renal toxicity of antibiotics.
Symptoms of acute renal failure:
Acute renal failure clinical manifestations of oliguria acute tubular necrosis. 3 phase:
Phase 1: the period of low urine. Decreased urine volume caused by hyperkalemia, water intoxication (severe edema, elevated blood pressure, pulmonary edema or brain edema), metabolic acidosis and acute uremia symptoms. Hyperkalemia and water intoxication were the main causes of death.
Phase second: multiple urine. Renal tubular epithelial cells regenerative repair urine volume gradually increased, so that blood potassium, blood sodium decreased, continuous polyuria patients can die of dehydration and electrolyte disorders.
Third phase: recovery period. Urine volume decreased to normal after polyuria, blood Bun, creatinine (Scr) and electrolyte returned to normal level, but renal tubular function and structure returned to normal still need 3 ~ 6 months. Failure to recover into chronic renal failure. Although non oliguria type of urine volume, but blood Bun, Scr increased daily and appear toxic symptoms, due to kidney injury is light, so prognosis is good.
Classification of diseases and symptoms of acute renal failure by reading the content we should have a detailed understanding of the understanding and classification of these symptoms can help patients with disease according to the type of good symptomatic treatment, renal failure disease in recent years the incidence gradually increased, so it is necessary to understand the basic knowledge of his.
