Renal Artery Ultrasound

Duplex ultrasound of the renal arteries to evaluate renal artery anatomy and stenosis as a culprit for uncontrolled hypertension.

INSTRUCTIONS FOR A RENAL  ARTERY  ULTRASOUND

• The test takes approximately 1 ¹/₂ hours.
• NOTHING TO EAT OR DRINK AFTER MIDNIGHT (or at least 6 hours before test).
• You will be asked to lie on your back, turning onto your right and left sides and possibly lying on your stomach during the exam. There is generally a great deal of “pushing” (which may be somewhat uncomfortable at times), which is done to achieve an ideal ultrasound picture.
