Now many people have learned that kidney is the body's most hard-working organ. Specifically, each kidney consists of nearly 1 million kidney units,there are many functions, including excretion of metabolites, regulating the body's environmental stability and endocrine, etc. Because the kidney is vulnerable to drugs, inflammation, etc. external injury in human evolution process of the formation of a strong reserve capacity, slight lesions are not easy to show. This has resulted in a lot of people in the cognitive misunderstanding, feel normal renal function can exclude nephropathy, but this is unscientific!
In fact, when kidney damage more than 50%will lose compensatory ability, thus showing symptoms of renal failure. At the same time, Kidney units are not as regenerative as stem cells,poor liver function can be restored through treatment of liver, but the nephron damage to a lost one, once you lose the ability to compensate,no severe doctors can cure it.Therefore, kidney disease is often hidden, usually even no obvious discomfort, some people appear symptoms of renal damage has progressed to uremia.
At present, renal function tests are the most used methods for determination of serum urea nitrogen and creatinine levels, the two indexes of renal damage in unit 50%, the test results are still normal, at the expense of more than 50%, will be abnormally high. In other words, normal renal function does not mean that the kidney must be no problem.
In simple terms, even check out renal function is normal, can not rule out kidney disease, in order to be responsible for their own body, Dr. stone suggest that you can do further checks to determine the specific circumstances of the body.
