Renal Artery Ultrasound

A renal untrasound is conducted on a patient to check blood flow to the kidneys.

Renal ultrasound is a test which utilizes high frequency sound waves to obtain images of your renal arteries. This test is used to determine if there are any problems with the vessels that supply blood flow to the kidneys. The technologist applies an acoustic gel on your abdomen over the area to be viewed. A painless instrument called a transducer is then gently moved across that portion of your body to visualize the inside of the arteries that carry blood to the kidneys.

Renal Artery Ultrasound

How is the test completed?

During the test you will be asked to lie on your back (if possible), while a trained technician records the images made by the ultrasound. The test usually takes less than 90 minutes. Renal aretery ultrasound does not hurt and there are no documented complications from the use of this type of ultrasound. During the test you may hear several strange noises coming from the machine. Do not become alarmed; these noises are actually the sound of blood moving through your body.

Are there any special preparations?

For three hours prior to the exam you should not smoke or use nicotine products. Avoid coffee, tea and all caffeine products. This test requires twelve hours of fasting and twenty four hours of fasting from dairy products. Please wear clothing that allows easy access to your abdomen.

How will I learn the test results?

The technician will not discuss any findings or conclusions about the test with you. Your personal physician is responsible for providing you with this information.
