Background: Arterial RI measurements by duplex Doppler USG have been advocated for the diagnosis of obstruction. In most centres, obstruction is indicated by an RI greater than 0.70 or a difference of greater than 0.10 between the kidneys. Our aim was to evaluate and compare the Doppler waveform alterations in unilateral acute renal obstruction (UARO) with the contralateral normal kidney as a control. Methods: 100 patients presenting to the emergency medical division with symptoms of unilateral acute renal colic were subjected to USG and Doppler USG. The renal RI was calculated in comparison to the collateral normal kidney. Results: The mean resistivity index (RI) was higher in obstructed kidneys in all cases. 80% patients had complete, while 20% had partial obstruction. RI value in completely obstructed kidneys was 0.72 versus 0.71; p
