The Place of Diuretic Enhanced Doppler Sonography in Distinguishing Between Obstructive and Non-obstructive Hydronephrosis in Children

Abstract

Kidneys with severe UPJ obstruction tended to have more elevated RI and PI values than the non-obstructed or equivocally obstructed ones. Again, determination of RIR values for each kidney showed the same elevation in severely obstructed kidneys, while non-obstructive or indeterminately obstructed ones demonstrated statistically insignificant changes.
