My ultrasound said abnormal resistive index on r kidney suggesting medical renal disease or renal stenosis. my kidney blood levels were all low?

High Resistive Index: I have two questions, why did your doctor order a resistive index on you? Do you have hypertension (BP) that is difficult to control? If you do not have any bp, then you likely do not have a renal artery stenosis (ras). If you do have bp, you may need a renal artery angiogram to see if your BP is caused by a ras. See a nephrologist for more answers. Good luck.
