The principles of treatment for chronic renal failure include early-stage non-dialysis conservative treatment as well as end-stage renal replacement therapy. Non-dialysis conservative treatment includes delaying the progression of kidney damage, which requires treating the primary disease, implementing nutritional support, and controlling factors that accelerate kidney disease progression, such as controlling high blood pressure, proteinuria, and hyperlipidemia. Additionally, it is necessary to eliminate metabolic waste from the body, and maintain the body's water, electrolyte, and acid-base balance. Renal replacement therapy includes hemodialysis, peritoneal dialysis, and kidney transplant therapy.
