If there is unilateral renal atrophy, it usually will not develop into uremia; if there is bilateral renal atrophy, it depends on the severity of atrophy, severe atrophy usually may develop into uremia in 3~5 years time, the specific time is related to the condition and the physical and other factors. When patients have unilateral renal atrophy, they generally do not develop uremia. Because when unilateral renal atrophy occurs, the other side of the kidney can be compensated to increase in size and perform the functions of both kidneys, thus ensuring the stability of renal function, therefore, it will not develop into uremia in general. If the patient has bilateral renal atrophy, the impact on the kidney is more serious when it is generally considered and not treated in a timely and appropriate way. After being stimulated by the metabolic waste in the body, patients may develop to uremia in 3~5 years. Patients with renal atrophy should go to regular hospitals in time and choose appropriate treatment to minimize the possibility of uremia.
