There are many causes of kidney failure, some of which can be cured and some of which are difficult to cure, as follows: 1. curable: patients with kidney failure caused by acute interstitial nephritis, acute tubular necrosis and other acute kidney injury can be cured after active treatment; 2. difficult to cure: if the kidney failure is caused by chronic nephritis, diabetic nephropathy and other diseases, it cannot be cured. Patients need to check kidney function, urinary routine, kidney ultrasound and other indicators to initially determine the condition and give targeted treatment after clarifying the cause, for example, for the treatment of acute interstitial nephritis, mainly using hormones. In the process of medication, pay attention to monitor the changes of relevant indicators and adjust the treatment plan according to the test results. In daily life, pay attention to the prevention of cold and flu, as well as do not stay up late and overworked.
