Renal Artery Ultrasound An Overview
A renal artery ultrasound is a non-invasive imaging procedure that uses sound waves to create images of the renal arteries. The renal arteries carry oxygen-rich blood to the kidneys.
Why is a renal artery ultrasound performed?
A renal artery ultrasound is performed to look for blockages or narrowing of the renal arteries. Your physician may also order a renal artery ultrasound to monitor existing renal artery disease or as a follow up after surgery.
Renal Artery Ultrasound What to Expect
How To Prepare
Your physician will explain all aspects of your testing during your visit. In most cases, patients will be asked to not eat or drink 8 hours before the ultrasound. Fasting before the ultrasound provides clearer visibility for the technician and physician.
What To Expect
During a renal artery ultrasound, you will lie on your back on an exam table. Your technician will apply gel to the transducer and carefully move the transducer around the abdomen to produce images on the renal artery. Your technician may ask you to roll over, hold your breath, or move during the testing to get a clearer image of the renal artery. The entire procedure takes about 60 minutes to complete and is typically performed in the morning.
Once the ultrasound is completed, your technician will wipe any excess gel from the abdomen. The renal artery ultrasound is a painless, safe procedure that generally takes one hour to complete.
