Webdiagnosed by no ﬂow in the renal artery. We have included two analyses. Our main analysis includes occlusion in the “greater than” groups so that it is those that have no ﬂow or a PSV equal to or greater than a speciﬁc velocity (eg, no ﬂow or a PSV 285 cm/s for 60% RAS). Another analysis is included where the occlu-sions were excluded. WebMultiple regression analysis confirmed the age dependence of the S/D ratio, PI, and RI of the renal artery in normal children. Renal vascular resistance continuously declines after birth and stabilizes at the age of 102-130 months.
