Renal Artery Ultrasound: What to Expect

Renal artery ultrasound is a non-invasive imaging technique used to examine the blood vessels that supply the kidneys. This procedure helps in diagnosing conditions such as renal artery stenosis, aneurysms, and renal artery thrombosis. If your doctor has recommended a renal artery ultrasound, you may be wondering what to expect during the procedure. Here is an overview of what happens during a renal artery ultrasound and some frequently asked questions about the procedure.

What to Expect During a Renal Artery Ultrasound:

Before the Procedure:
Before the renal artery ultrasound, you will be asked to change into a hospital gown and lie down on an examination table. It is important to inform the technician if you have any metal implants or are pregnant, as these may interfere with the procedure.

During the Procedure:
A gel will be applied to your abdomen or groin area to help transmit soundwaves. The technician will then use a device called a transducer, which emits high-frequency soundwaves, to capture images of your renal arteries. The transducer will be moved around the area to obtain different angles and images. You may be asked to hold your breath briefly during the procedure to minimize movement.

After the Procedure:
Once the ultrasound is complete, the gel will be wiped off, and you can get dressed. The images will be analyzed by a radiologist, who will provide a report to your doctor. Your doctor will then discuss the results with you and recommend any further diagnostic tests or treatments if necessary.
