REMINDERS RI normal ~ 06, up to 0.8 = (peak systolic- diastolic) / (peak systolic) Transplanted kidneys RI > 0.9 is a nonspecific marker of transplant dysfunction If elevated RI, look more carefully for renal artery waveform - tardus parvus waveform suggest stenosis at anastomosis Resource on transplanted kidney US |
