Chronic kidney disease cannot be cured, but can only slow down the progression of renal function. Chronic kidney disease refers to renal structural or functional abnormalities for ≥3 months due to various causes, including the presence of signs of renal injury (albuminuria, abnormal urinary sediment, tubular-related lesions and abnormal imaging tests, etc.) or a history of renal transplantation, with or without a decrease in glomerular filtration rate; or unexplained decrease in glomerular filtration rate (<60 ml/min) for ≥3 months. Chronic kidney disease cannot be cured, its prevention and treatment is systematic and comprehensive. Early diagnosis, active and effective treatment of primary diseases, avoiding and correcting risk factors that cause progression and deterioration of renal function are the basis of prevention and treatment of chronic renal failure, and also the key to protecting renal function and delaying the progression of chronic kidney disease. Patients with chronic kidney disease should go to the hospital in time and be treated under the guidance of professional doctors in order to avoid the deterioration of kidney function.
