how renal failure is caused

First, renal failure caused by many reasons. Generally includes three aspects:
1, drugs: nephrotoxicity drugs used improperly long-term damage to the kidneys and renal failure after accumulation reaches a certain degree. Such as painkillers, painkillers containing phenacetin, long-term taking damage the kidneys, causing chronic interstitial nephritis, which in turn develop into renal failure; In addition, such as gentamicin drug use undeserved can also cause kidney failure.
2, misdiagnosis: due to renal failure symptoms similar to other system diseases, therefore easy to misdiagnosis, during the process of diagnosis delay treatment, so as to make the continuous deterioration of kidney disease, increased damage to the kidney, resulting in the chronic renal failure. Patients with symptoms of anemia, for example, from the point of view because of the lack of kidney disease common sense, according to anemia, on mild symptoms such as fatigue, fatigue, high blood pressure, night urination much and ignore as well as the economic conditions restrictions delayed illness; From the aspects of the doctor said, satisfied with symptom diagnosis, ignoring the accompanied by complications, and to do related inspection is lead to misdiagnosis, delay treatment, resulting in chronic renal failure.
 3 and symptoms due to renal failure is caused by a variety of chronic kidney disease (CKD) development to late kidney function loss of some or all of the pathological state, so like may cause chronic renal failure of some chronic diseases including primary glomerular nephritis, diabetic nephropathy, hypertensive nephropathy, renal interstitial tubular kidney disease, such as polycystic kidney disease is the cause of renal failure.
Second, from the perspective of disease, kidney failure caused by the reasons generally have:
1. Congenital kidney disease, most common to polycystic kidney disease (CKD), the expert points out, this is a kind of hereditary disease, divided into two kinds of explicit and implicit, generally about are dominant, often in the middle before onset;
2. The lesions caused by kidney itself, usually this kind of renal failure happens, in addition to a few people who can recover, most patients are unable to heal, and will continue to deteriorate, silk ball like kidney nephritis, renal silk ball like the inside of the so-called a filter, filter function is useful and good things to stay, not good such as urine and eliminate toxins, when the filter problems, kidney function will not be able to function properly, so it caused the renal failure, how to renal failure caused by clear now;
3 of the cause caused by other diseases and renal failure, is currently the highest percentage of diabetes, lupus, or other red class gout and other diseases, can cause chronic renal failure.
Three, acute renal failure caused by the reasons are as follows:
The first kind is the kidney itself lesions caused by renal failure;
The second is renal failure caused by other organs lesions, such as heart disease, cirrhosis of the liver, or lung hypoxia, there are may cause renal failure
