A Renal Duplex uses ultrasound to evaluate the blood flow to the kidneys. This non-invasive test does not use needles, drugs or dyes. The test will be performed by a highly skilled ultrasound technologist.
Gel is placed on the skin over the area to be studied. A hand held transducer is used to make the pictures. The pictures will show the walls of the arteries, the blood flow through the arteries and the kidneys. The velocity of the blood flow will be measured. This will pinpoint the level and severity of disease, if any. The doctor may order additional testing if this study is abnormal. Patient Instructions:
- Allow 1 hour for the test.
- Wear two-piece clothing.
- Take all of your regular medications, unless otherwise instructed by your physician.
- Do not eat or drink anything after midnight the night before the test.
- Your physician will be notified of the results.
If you need to reschedule the test or have any questions regarding these instructions, please call our office.
