How to distinguish acute and chronic renal failure

Renal failure is a common disease in clinic, which is pided into acute renal failure and chronic renal failure. If acute renal failure can be diagnosed accurately and treated reasonably, it can be cured or relieved. The distinction between acute and chronic renal failure is clinical diagnosis, mainly based on the length of the disease, referring to other indicators; two is the pathological dispute, renal biopsy pathological diagnosis is the standard of acute renal failure.

1. The duration of disease is the basis of differentiating acute renal failure from chronic renal failure. In 50 cases of chronic renal failure, half of the disease period is less than 1 years, three cases in one of the disease is more urgent, the disease duration is less than 3 months. Therefore, the duration of disease is the basis of judgment, especially chronic renal failure is not reliable.

2. It is generally believed that the increase of renal volume is found in acute renal failure, and the decrease of renal volume is seen in chronic renal failure.

3. Nail creatinine determination is a noninvasive and simple method, and the measured value reflects the level of serum creatinine three months ago. For patients with occult onset or unknown history and normal size of the kidney, the measurement of nail creatinine can be used to understand renal function 3 months ago.

4, anemia of chronic renal failure is one of the clinical manifestations, as one of the differential diagnosis of acute renal failure and chronic renal failure of kidney, sampling analysis showed no significant difference in the detection rate of acute renal failure and anemia in patients with chronic renal failure and severity.

5, nocturia and urinary weight loss are the clinical manifestations of chronic renal failure. In the patients with acute renal failure, half of the urinary gravity is less than 1.015, and the renal biopsy tissue has tubular interstitial lesions. This phenomenon can explain the decline of urinary gravity in patients with acute renal failure.

6. The increase of urease, brush border antigen and urinary adenosine binding protein in acute renal failure, especially acute tubular necrosis, is beneficial to differential diagnosis

The above is about how to distinguish between acute and chronic renal failure, hoping to help you, if you have a kidney disease knowledge requires a detailed understanding, you can consult our online expert, our experts will answer for you.
