The survival time of renal atrophy cannot be generalized and is closely related to the severity of the disease and kidney function. Usually, once a patient progresses to the uremic stage, his or her survival period may only be about 10-20 years. The degree of kidney atrophy varies, as does the severity of the disease and kidney function. Atrophy of one side of the kidney, the most common cause of which is renal artery stenosis, usually has little impact on life expectancy if the patient has no abnormal kidney function. In the case of bilateral renal atrophy caused by chronic glomerulonephritis, hypertensive renal damage, IgA nephropathy, etc., it has little impact on the life expectancy of the patient if the renal function is maintained stable for a long time. However, if the double kidney atrophy combined with renal failure, has entered the uremic phase, the survival time of patients may be relatively shortened, in the active control of the original disease, such as to ensure stable blood pressure or the usual diet more regular, less underlying disease, through dialysis can often maintain 10-20 years of life. Patients with renal atrophy should actively treat the primary disease and can protect the function of both kidneys by taking traditional Chinese medicine. It is also recommended to go to the nephrology department of the hospital for regular checkups, pay attention to lifestyle adjustment and regular medication.
