Stage 2 nephropathy refers to chronic kidney disease stage 2, which is usually not completely curable but can slow disease progression and control complications. 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, tubular-related lesions, abnormal histologic examination, and abnormal imaging) 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. Therefore, Stage II Nephropathy is a chronic kidney disease in which irreversible damage to the kidney occurs and usually cannot be cured. However, you can actively treat the primary disease, delay the progression of renal function, control complications, etc.. Patients with chronic kidney disease are advised to visit regular hospitals in time and standardize treatment under the guidance of doctors.
