A Renal Arteries/Renal Stent Ultrasound is a scan using ultrasound waves to assess the blood vessels of your kidneys. A common reason for having this examination is that your doctor is investigating your high blood pressure. There are many reasons why this could be occurring and this ultrasound will assist in diagnosis. For more information please see our patient information brochure for this examination.
As there are a range of reasons why you are having this test, it is best discussed with your doctor.
- You will be taken to a private room. A staff member will explain the procedure and answer any questions you may have.
- You will be asked to remove clothing from your abdominal area.
- Gel is placed on the area of interest so that sound waves can pass through to the relevant vessels. You will be lying on your back initially.
- You will then be asked to roll on either side to have a differing view of the blood flow into your kidneys.
- As your kidneys move with respiration, you may be asked to hold your breath.
- You will hear the Doppler ultrasound from time to time as it makes a pulsing noise.
- This examination takes approximately 60 minutes.
