The specific cause of kidney failure needs to be clarified to determine whether the disease can be cured. For example, if the kidney failure is caused by acute kidney injury, like acute interstitial nephritis, acute tubular necrosis and other diseases, it can be cured after active treatment. If the kidney failure is due to chronic kidney diseases like chronic nephritis and diabetic nephropathy, it cannot be cured completely. By checking renal function, urine routine, urine protein quantification, renal ultrasound, electrolytes, blood routine, parathyroid hormone and other items, we can assess the patient’s condition so as to formulate a targeted treatment plan. Kidney failure continues to progress and deteriorate is uremia, need to start dialysis treatment, in the process of treatment, pay attention to regular follow-up review, monitor the condition changes.
