Acute renal failure symptoms are divided into three periods

As people realize the complexity of kidney failure, so on the symptoms of kidney failure is divided into three periods, each period is significantly different, the symptoms of patients and doctors can make a accurate judgment according to the patient's symptoms: the severity of the disease, treatment means, these can be based on the stage.
In clinic, according to the amount of urine in patients with the symptoms of kidney failure stage can be divided into oliguria and non oliguria.Acute renal failure with oliguria or anuria behavior called oliguria type.Non oliguria refers to the blood urea nitrogen, serum creatinine height quickly, quickly reduce the creatinine clearance, and without oliguria performance;Clinical common oliguria acute kidney failure, clinical process divided into three phases:
(1) oliguria stage: urine fewer symptoms may last week, but what is certain is that the longer the duration, renal damage is heavier, less urine is more than 5 days, or no urine, greater than 0 days not bad prognosis.Oliguria stage system symptoms are: 1, water, sodium retention, water poisoning children can be characterized by edema, hypertension, pulmonary edema, brain edema, and heart failure, due to water retention can appear sometimes diluted hyponatremia.2, electrolyte disorders common high potassium, magnesia, high phosphorus and low calcium and low in sodium and chlorine.
(2) the polyuria time: excessive urine volume is also a sign of kidney disease appeared, the phenomenon such as too much easy to cause dehydration of urine.When children with ARF urine, anasarca, 4 hours and more than 50 ml/m of urine, which is the diuretic stage, this period due to a large number of micturition, can appear dehydration, low sodium, and hypokalemia.Late early nitrogen qualitative hematic disease continues even aggravate, renal function recovery gradually.
(3) restore diuresis, this stage kidney disease is a commonly after improving, the urine gradually returned to normal, various indicators also improved significantly.Blood urea nitrogen and creatinine gradually returned to normal, and renal function of enrichment need months to return to normal, the legacy of a few patient part irreversible renal damage.This period can be characterized by weak children, angular, malnutrition, anemia, and a weakened immune system.
