I've Been Misled a Lot on Renal Duplex Ultrasound

The other option obviously is renal duplex ultrasound and I feel like I've been misled a lot of times by either regular ultrasound or duplex ultrasound. If you have a high suspicion for bilateral stenosis the key is repeat the imaging because if their kidney is truly ischemic it can really shrink rapidly. The patient that I saw from an outside location nephrologist was appropriately concerned about it did an ultrasound kidneys were normal size sent them to my clinic. Within a couple of months the kidney had really shrunken to basically a non-functional size so it was very clear that they had something and a vascular insult to that kidney.
