title: Progression of mild ureteropelvic junction obstruction in infancy.
abstract: Mild and clinically silent ureteropelvic junction obstruction was observed to progress in severity in 2 infants. Diuretic renography was useful in serial evaluation and documentation of progression. The possible mechanism for such progression of obstruction is proposed. Although mild obstruction in the older child and adult can be followed successfully without surgery, it appears that close follow-up of mild obstruction during the first year of life is necessary to detect and assure treatment of progressive obstruction at an optimum age.
