Renal Doppler Ultrasound

What is a Renal Doppler Ultrasound?

A Renal Doppler Ultrasound is a non-invasive test used to measure the blood flow through the arteries that supply blood to the kidneys.

How does it work?

Ultrasound gel will be placed on your abdomen. The Sonographer will use a small hand-held device that emits sound waves to produce images of your arteries on your abdomen and ribcage. From those images, an assessment is made and then reviewed by a Vascular Surgeon.

How do I prepare for the test?

You will need to fast for 8hrs NBM (nil by mouth) prior to having a Renal Doppler Ultrasound. DO NOT fast if you are a Diabetic. To ensure your kidneys are well hydrated for the ultrasound, you must drink plenty of water prior to your test appointment so that your bladder is full.  Take your medication as usual. Wear clothing that can be easily removed from the waist up.

How long does the test take?

A Renal Doppler Ultrasound takes approximately 30 minutes.
