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 caused by chronic kidney disease such as chronic nephritis and diabetic nephropathy, it cannot be completely cured. By checking kidney function, urine routine, urine protein quantification, kidney ultrasound, electrolytes, blood routine, parathyroid hormone and other items, we are able to assess the patient’s condition and thus make a targeted treatment plan. Kidney failure continues to progress and deteriorate is uremia, and dialysis treatment needs to be started. In the process of treatment, attention is paid to regular follow-up reviews to monitor changes in the condition.
