A A 8-month-old boy with right hydronephrosis, Doppler image depicting resistive index of 0.82 in the affected right kidney, where in the waveform shows a delayed upstroke with reduced frequency, indicating resistance to the vascular flow and signifying obstruction. B Doppler sonography image of the child post-intervention at 6 months depicting, resistive index of 0.60 in the affected right kidney, where in the waveform shows a rapid upstroke with a good amplitude and increase in frequency, indicating least resistance to the vascular flow following relief of obstruction
