Acute renal failure and chronic renal failure have different clinical manifestations

Referred to as acute renal failure acute renal failure, acute renal failure progression fast , usually caused by insufficient blood supply of the kidney ( such as trauma or ) , due to some factors of kidney function is impaired or blocked by the poison caused damage caused by acute renal failure generation. Acute renal failure fair treatment if the correct diagnosis can often be cured or alleviated.
And chronic renal failure, chronic renal failure, short , mainly due to the long primary kidney disease, reduced renal unit being destroyed , along with the time and the disease, resulting in renal excretory function and endocrine and metabolic function swap serious damage caused by water and electrolytes , acid-base balance disorders , decreased kidney function , resulting in renal failure .
In addition to the quality of nitrogen sanguine disease , but often have no clinical symptoms, but only showed symptoms of the underlying disease , time to disease progression of residual renal unit can not adjust the minimum requirements to adapt to the body , then gradually manifested symptoms of uremia . Mainly as metabolites retention, water, electrolyte and acid-base balance and its system involvement .
Can be concluded from the above , acute renal failure and chronic renal failure to distinguish between :
Acute renal failure and chronic renal failure, what is the difference : clinical diagnosis , mainly based on history wrong, reference to other indicators .
Acute renal failure and chronic renal failure, what is the difference : ? Pathological diagnosis , biopsy and pathological diagnosis is to identify acute renal failure and chronic renal failure the gold standard , but the condition of the domestic hospitals have emergency biopsy is not yet widespread. Therefore, the selection and evaluation of acute renal failure and chronic renal failure identification noninvasive indicator is extremely important clinically .
What distinguish between acute renal failure and chronic renal failure have a lot of studies show ? :
As a basis for non- assertion of disease , especially chronic renal failure not reliable.
Currently has spread with "B" super measure kidney size . Generally thought that kidney volume increase seen in acute renal failure, renal volume reduction seen in chronic renal failure. Our data indicates either acute or chronic renal failure, kidney real increase or decrease each by only one-third the size of normal kidneys in most cases , people in this part of the application of B- measuring kidney size on acute and chronic renal failure identification no help . Recently, we found that "B" super over the next measure the thickness measurement of renal parenchymal volume size is more meaningful .
Nail creatinine measurement is a non-invasive , convenient method of prosecution , the measured value of serum creatinine reaction three months ago . Patients with a history or ominous about the insidious onset , the size of a normal kidney , nail creatinine measurements can understand three months ago of renal function, and its specificity was 84% , can be used as fill these two materials.
