kidney and the difference between the mean resistive indices of both kidneys were calculated before and after administration of 0.5 mg furosemide per kilogram of body weight. A receiver operating characteristic curve was generated to determine the discriminatory resistive index value for diagnosing obstruction. Resistive indices were not significantly different between kidneys with non-obstructive dilatation and normal kidneys before and after diuresis. Significant differences in resistive indices before and after diuresis were seen between kidneys with obstructive dilatation and kidneys with non- obstructive dilatation and between normal kidneys. Kidneys with obstructive dilatation showed a significant increase in resistive index after administration of furosemide. In the indeterminate kidneys, furosemide had a heterogeneous effect on the resistive indices, indicating obstructive resistive indices in five kidneys and non- obstructive resistive indices in four kidneys. Receiver operating characteristic analysis revealed a diuresis resistive index of O. 75, which resulted in an accuracy rate of 95 in diagnosing renal obstruc- tion. The authors conclude that Diuresis Duplex Doppler Sonography is accurate in the differentiation of obstructed from non-obstructed kidneys and may facilitate the distinction between obstructive and non- obstructive hydronephrosis, notably in kidneys classified as indeter- minate according to diuretic renography.
