How long can the right kidney atrophy with only one kidney live depends on the function of the patient’s left kidney, his own physical condition and other aspects, which cannot be generalized. If the right kidney is atrophied and the function of the left kidney is completely normal, the patient’s physical condition is better and one kidney can basically meet the physiological needs, which usually does not affect the patient’s life expectancy and can survive for a long time. If the right kidney is atrophied and the function of the left kidney is not normal, it may lead to renal failure or even progress to uremia, hemodialysis or peritoneal dialysis can prolong the life span and the survival time is about 10 years or more. If the right kidney is atrophied and the function of the left kidney is normal, but the patients themselves have underlying diseases such as hypertension and diabetes, or autoimmune diseases such as systemic lupus erythematosus, the survival prognosis may also be affected, and the specific time varies from person to person. Early treatment with TCM can delay the course of the disease. Patients with right kidney atrophy need to review renal ultrasound and renal function regularly in the nephrology department of regular hospitals to find out the problems and deal with them in time; if necessary, the diseased kidney needs to be removed to ensure the function of the healthy side of the kidney.
