Hydronephrosis in Children: When Is Treatment Necessary?
Hydronephrosis in children is one of the most common congenital urological conditions, characterized by dilation of the renal collecting system due to impaired urinary drainage. Treatment decisions should be based on renal function, the underlying cause of obstruction, and disease progression rather than the degree of dilatation alone. Early diagnosis and timely intervention are essential for preserving long-term kidney function.
