WebRI < 0.70 was noted in all children above 6 years of age; however, in younger children, RI > or = 0.70 was observed in 72.5% (37 of 51) of children. Resistance index in early childhood was considerably higher as compared with older children and the adult population: Apparently the RI value drops to adult level at approximately 6 years of age. WebBackground: The pulsatility index (PI) and the resistive index (RI) are used as pulsed-wave Doppler measurement of downstream renal artery resistance. Little information is available on their value in chronic renal failure and their correlation to parameters of renal function and haemodynamics.
