Chronic kidney disease stage 3 is usually not curable, but the progression of kidney disease can be slowed by aggressive treatment. Chronic kidney disease is a structural or functional abnormality of the kidney for ≥3 months from various causes, including the presence of markers of renal injury (albuminuria, abnormal urinary sediment, tubule-associated lesions, histologic abnormalities, and imaging abnormalities) or a history of renal transplantation, with or without a decrease in glomerular filtration rate; or unexplained decrease in glomerular filtration rate for 3 months. Chronic kidney disease stage 3 is defined as glomerular filtration rate between 30 and 59 ml/min, at this time the patient’s kidneys have been irreversibly damaged, therefore, chronic kidney disease stage 3 is usually not curable. However, it can actively treat the primary disease, slow down the progression of renal function and control complications. Patients with chronic kidney disease are recommended to visit regular hospitals in time and standardize the treatment under the guidance of doctors.
