Symptoms of acute renal failure which

In fact, not everyone thinks of kidney failure several causes, in fact, there are many causes of acute renal failure, and the incidence of speed is very fast. Normal kidney metabolites can be discharged to ensure human health, but the kidneys are damaged, you can not work properly, pose a threat to human health. So, acute renal failure symptoms, what does? Below Xiaobian to introduce several!

1, polyuria period: in little or no urine after 9 to 14, such as 24-hour urine volume increased to more than 400ml, is the beginning of polyuria, general daily urine output of up to 3000ml or more. This period of approximately 14 days, a sudden increase in urine output can be gradually increased or slowly increasing, the latter a poor prognosis. Polyuria renal function has not been fully restored, a major complication of hypokalemia and infection. Visible when the clinical treatment of patients gradually increased urine output, when the daily urine volume of 500 ml or more, it is called polyuria. In the initial period of polyuria, urine output, although increased, but the renal clearance rate is still low, the accumulation of metabolites remains. About 4-5 days, blood urea nitrogen, creatinine gradually decreased with increased urine output, along with improvement in symptoms of uremia. Polyuria in patients after physical weakness, still disorders and anemia, and needed to be several months to return to normal.

2, little or no urine period: tubular necrosis stage, adult 24-hour urine volume less than 400ml of oliguria; insufficient 100ml is no urine. This period is usually 7 to 14 days, with an average of 5 to 6, 2009, up to one month or less. Relatively low specific gravity is fixed, generally between 1.010 ~ 1.014, often urine protein, red blood cells and casts. Bleeding tendency: platelet factor Ⅲ deficiencies and defects, so that capillary fragility; liver dysfunction, prolonged prothrombin time, often subcutaneous, oral mucosa, gums and gastrointestinal bleeding, increased blood urea nitrogen and elevated serum potassium , or even disseminated intravascular coagulation. Metabolites accumulate: protein metabolites excreted by the kidneys can not, nitrogenous substances accumulate in the blood and showed azotemia, expressed as blood urea nitrogen, creatinine increased. Meanwhile in blood phenol, toxic substances such as guanidine also increased, the formation of uremia. Nausea, vomiting, headache, irritability, irritability, fatigue, weakness, confusion, and even coma. Patients usually lasts one week to two weeks, the elderly up to a month or more, the longer the duration, the more severe kidney damage, persistent oliguria more than five days, or no urine is greater than 10 days, the prognosis is not bad. Oliguria integrated system symptoms: nausea, vomiting, loss of appetite and other metabolic acidosis performance; edema, hypertension, pulmonary edema, cerebral edema and heart failure Shuinazhuliu performance; potassium, sodium, calcium High magnesium, phosphorus and high electrolyte imbalance such as low chlorine hyperlipidemia performance; respiratory tract infections, urinary tract infections.

3, water, electrolyte and acid base balance disorders: Due oliguria or anuria accumulation of a large body of water can be manifested as nausea, vomiting, dizziness, drowsiness and even coma. Limited due to raised potassium, potassium can be rapidly increased arrhythmia, ECG abnormalities, and even cardiac arrest, accompanied Hypermagnesemia neurological symptoms, such as muscle weakness, coma, abnormal electrocardiogram. Acute renal failure to reduce phosphorus excretion in the kidney, intestinal excretion and turn, with calcium to form insoluble calcium phosphate, calcium absorption effect, thus hypocalcemia, can lead to convulsions, increased myocardial damage hyperkalemia . Patients with varying degrees of renal impairment based on its recovery of renal function at different speeds, three months to a year gradual recovery of renal function, renal function in most patients recovered to normal levels, only a small number of patients to chronic renal failure.

The above is about the symptoms of acute renal failure, and hope that the majority of patients with acute renal failure must go to the hospital for timely treatment, because the longer the time for their own harm is very great!
