Divided into acute and chronic renal failure , acute and chronic renal failure, and that is how to distinguish ?
Acute and chronic renal failure distinction , one 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 two of the patient's standard , 100 cases of renal failure in patients after analysis of the clinical data showed that :
1, the duration of the disease is to distinguish between acute and chronic renal failure basis . 50 patients with chronic renal failure as much as half a foot of disease not years, of which one-third more acute onset of disease less than three months. So, as a conclusion based on the length of disease , especially chronic renal failure not reliable. Statistics show that the higher the diagnosis change after biopsy ratio.
2 , has become popular with the current domestic "B" super measure kidney size . Generally considered kidney volume increased in acute renal failure, renal smaller size seen in chronic renal failure . Our data suggest that either acute or chronic renal failure, kidney real increases or decreases each only one-third of patients , the vast majority of cases the size of a normal kidney , which some people use B- measuring kidney size on acute and chronic kidney failure identification no help. Recently exhibit "B" super measured over the measured thickness of renal parenchymal volume size is more meaningful .
3 , nails creatinine measurement is a noninvasive, simple screening method , which measures the value of serum creatinine reaction three months ago . For insidious onset or illness records is unknown, the size of a normal kidney patient , nail creatinine measurements can recognize three months ago kidney function, and its specificity was 84% , as more than make up for the 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 patients , anemia detection rate and severity . Additionally , hemolytic uremic syndrome, caused by high creatinine acute renal failure may exhibit severe anemia , acute renal failure, acute dilatation may cause mild to moderate anemia. Due to acute interstitial nephritis erythropoietin hormone produced lower acute nephritis also be expressed as anemia.
