Method to distinguish between acute and chronic renal failure！

Suffering from renal failure, acute renal failure, or for chronic renal failure to determine how to distinguish between acute and chronic renal failure approach, what does? Divided into acute renal failure is chronic, acute renal failure Broadly speaking, there are renal, kidney ago after sex and renal, acute renal failure, also known as acute tubular necrosis narrowly, is due to hypoxia, ischemia and renal tubular cause of poisoning. Chronic renal failure is caused by illnesses reasons, resulting in chronic renal parenchymal damage, renal damage, causing water and electrolyte imbalance, azotemia, acid-base balance disorders and other symptoms. Distinction between acute and chronic renal failure less specific way, what does? 
What is another way to distinguish between acute and chronic renal failure acute and chronic renal failure distinction, first clinical diagnosis, mainly based on the length of illness records, reference to other indicators;? Second, the pathogenesis of the diagnosis, pathogenesis of renal biopsy diagnosis is to identify the two patients standards, but the current conditions of domestic hospitals have emergency biopsy is not yet widespread. Therefore, the selection and evaluation of the clinical identification of two patients with non-invasive indicator is extremely focused. Clinical data on 100 cases of renal failure patients were analyzed, the results showed: 
1, disease duration is to distinguish acute and chronic renal failure basis. 50 cases of chronic renal failure patients as much as half a year of not feet, of which one third more acute onset, disease duration less than three months. So, as a conclusion based on the length of disease, especially chronic renal failure not reliable. Statistics show that a high change after renal biopsy diagnosis of proportion. 
2, currently the country has been popular with the "B" super measure kidney size. Volume increase seen in the kidney usually considered acute renal failure, kidney smaller size seen in chronic renal failure. Our data show that regardless of acute or chronic renal failure, kidney real increases or decreases each accounted for only one-third of patients, the vast majority of cases of kidney size is normal, this part of the application B-measure kidney size on acute and chronic renal failure to identify without help. Recently exhibit "B" super measured thickness than the measured renal parenchymal renal volume size more meaningful. 
3, nail creatinine measurement is a non-invasive, simple screening method, which measures the value of serum creatinine reaction three months ago. Against the insidious onset or illness records is unknown, the size of a normal kidney patient, nail creatinine measurements can recognize three months ago of renal function, and its specificity of 84%, can be used as make up more than two materials. 
4, anemia is one of the symptoms of chronic renal failure, acute renal failure, as one of the identification points with chronic renal failure, no significant difference in the analysis of 100 cases of acute renal failure and chronic renal failure, anemia detection rate and severity. In addition, hemolytic uremic syndrome caused by high creatinine acute renal failure may exhibit severe anemia, acute renal failure, acute expansion can cause mild to moderate anemia. Erythropoietin due to acute interstitial nephritis acute nephritis hormone produced lower also be manifested as anemia. 
5, urine increased, urine specific gravity is reduced symptoms of chronic renal failure. Half of the cases of acute renal failure urine specific gravity of less than 1.015, biopsy cells are noticeably tubulointerstitial lesions, this phenomenon is explained by lower specific gravity of acute renal failure. 
The above is my hospital for acute and chronic renal failure kidney specialist at the judgment method of explanation, I hope to patients to help a friend!
