The clinical manifestation for renal failure patients

  We are familiar with acute renal failure. Nowadays people are all terrified for the high incidence of acute renal failure, while few know the pathological change of it. In reality, patients will suffer from different clinical manifestation in different stages. Now let’s talk about the common syndromes of acute renal failure.

  First, oliguria stage. This stage may sustain one or two weeks, four to six weeks if long. The longer the time is, the more serious the kidney injury is. If the oliguria is more than five days or the anuria is more than 10 days, prognosis will be undesirable. The symptoms in this period include edeam, hypertension, lung edema, celebral edema and cardiac failure.

  Second, diuresis stage. In this period, the whole edema will relieve, urine volume will reach 250ml/m2/24 hrs, which will last one or two months. Due to diuresis, patients may suffer dehydration, hyponatremia and hypokalemia.

  Third, convalescence. After diuresis stage, the kidney function will be improved, the urine volume will keep in the normal degree. In this period, the blood urea nitrogen and creatinine level will recover to the normal level. The symptoms in this period include weak, emaciation, malnutrition, anemia, low immunity.
