Abstract

|
|
In hydronephrosis, it is very important for its management to determine. RI value using Dopler sonography is one of the least invasive modality available for differentiating the obstructed from the nonobstucted dilated upper urinary tract and
particulaly useful in following the patient who has hydronephrosis. However its normal value and discriminating point were not established yet in children. To assess better utility of RI in diagnosis of obstructive hydronephrosis, we evaluated 66
undilated renal units with the intention of establishing a nomogram of RI values in children. There was no significant relationship between the RI value was 0.74±0.07 in this study and 22 of 66 undilated kidneys (33.3%) had RI values above 0.7,
which
has thought to be discrminatory value in abult. We think that RI values of normal kidneys need to be evaluated further in children.
