According to the latest medical statistics, approximately one in every three infants and adolescents has unilateral renal hypoplasia. For most patients with no apparent symptoms, treatment or surgery is not required, and their quality of life can remain normal.

However, children should pay special attention to reducing kidney burden in their daily diet to avoid excessive strain on the kidneys.
