Can Doppler index–RI be a predictor of renal colics impending obstruction in acute and emergency clinical settings.
To compare the results of RI in cases of obstructive, nondilated and normal kidneys.
A total of 90 patients were included in this prospective study. The patients were grouped into three categories based on the clinical settings. Group 1 with acute unilateral obstruction were 44, group 2 who were presented with flank pain without stone disease were 26 and group 3 were 20 patients with sonologically normal kidneys.
Grey scale ultrasonography and colour Doppler study carried out in all the groups and index – RI value were compared.
The study showed differences in RI values among the groups (0.726±0.04, 0.63±0.039 and 0.608±0.03 respectively).
In acute and emergency clinical setting, grey scale ultrasonography and interrogation with colour Doppler index– RI improved the assessment and detection of impending obstructive uropathy.
