In this group of patients difference in differential function on renogram is not a reliable way of predicting the need for surgery as both the renal units may have deterioration of function which would not be reflected in the percentage difference in function.

The important questions to be answered during follow up of these infants are: This area, where the dilatation has stabilized in the early childhood, has hitherto not been investigated thoroughly and further studies are awaited to look into the fate of those kidneys later in life. In a normal kidney one expects a rapid transit with more or less homogenous kidney filling in about 2 min.

Correlation of hydronephrosis index to society of fetal urology hydronephrosis scale. Therefore, features such as calyceal dilatation and parenchymal thinning should also be considered in grading the severity of hydronephrosis.
