Clinical features and differential diagnosis of acute renal failure

Acute renal failure is a syndrome. For a variety of reasons cause, glomerular filtration rate decreased rapidly below 50% of normal, blood urea nitrogen and serum creatinine increased rapidly and cause water substance disorders and disorders of acid-power balance base and symptoms of acute uremia. Acute renal failure is observed in disease subjects, acute renal failure and chronic renal failure are different, such as early diagnosis and timely rescue, renal function is fully restored, such as delayed treatment may be fatal . The prognosis of the primary disease, age, diagnosis and treatment sooner or later, if you want to combine multiple organ failure, and other factors.

Clinical manifestations

1. Oliguria: (1) Three low (sodium, calcium, reduced pH), three high (potassium, phosphorus, creatinine increased), edema (2) uremic symptoms may include nausea, vomiting, gastrointestinal bleeding, difficulty. breathing, coughing, chest pain, hypertension, heart failure, drowsiness, mental confusion, tremors and epileptic seizures, anemia and bleeding tendency etc. (3) Infection according to the site of infection to produce symptoms.

2. The time of much urine: The function of the kidneys failed to restore, blood urea and creatinine continues to rise, and prone to dehydration, infection, hypokalemia, gastrointestinal bleeding etc.

3. Convalescence: blood urea nitrogen and creatinine near normal, urine output gradually returned to normal, the role of glomerular filtration rate in 3-12 months more back to normal.

Differential Diagnosis

based diagnosis

1. There shock or hemolysis, drug toxicity or intravascular allergies.

2. By correcting or exclude acute hypovolemia, dehydration, urinary tract obstruction, urine remains ≤ 17 / ml / hu urine remains ≤ 400 / ml / 24h.

3. Specific gravity of urine in 1015 or less, and even set to 1,010.

4. Abrupt onset and increasing azotemia.

5. The urine osmolality <350mOsm / Kg.H2O, urinary sodium> 40 mmol / L.

6. Except prerenal and postrenal azotemia little or no urine.

Symptoms of kidney failure

Patients with renal impairment should be aware of the signs and symptoms can worsen kidney function and may warrant evaluation and treatment of your nephrologist.

What are the symptoms of acute renal failure?

Swelling, especially in the legs and feet

Lack of appetite, feeling not like to eat

Nausea and vomiting

When you urinate, little or no urine

lumbago

Anxiety, confusion, disturbed and drowsiness

What are the symptoms of chronic kidney failure?

Since decreased renal function, symptoms of kidney failure are unable to regulate water and electrolyte balance, removing waste from the body, and promotes the production of red blood cells.

Swelling: Because the kidneys can not adjust the balance of the wastewater.

Proteinuria: glomerular damage, Protein molecules can pass filtration membrane, at this time, otherwise it may be damaged tubular, proteins can not be reabsorbed.

Anemia: Tenal not produce erythropoietin (EPO), and to promote the production of red blood cells. In addition, toxins in the body shorten the life of the red blood cells.

High levels of creatinine: For body can not excrete creatinine. Lack of appetite, fatigue, drowsiness and even coma: because the creation of waste products in the blood. Anemia can also aggravate these symptoms.

A shortness of breath: Because the kidneys are unable to meet the growing burden of acid in the body.

Hypertension: As the body of excess fluids

Nausea and vomiting
