Renal Artery Duplex Scan

Renal Artery Duplex ScanA renal artery ultrasound allows visualization of the arteries to the kidneys located in the abdominal area. This evaluation detects any blockage or narrowing by measuring the speed of blood flow through these arteries. This test also includes an evaluation of the abdominal aorta, kidney size and texture (for signs of obstruction of urine flow or atrophy). Blocked kidney arteries can result in severe hypertension or progressive kidney failure leading to kidney failure and dialysis.

Pre procedure instructions:
Nothing by mouth after midnight. You may take your medications with sips of water the morning of the test. You should wear comfortable, loose fitting clothing for your ultrasound. An open necked shirt or blouse is ideal. You will need to remove all clothing in the area to be examined.

What to expect:
For most ultrasound exams, you are laying face up on an exam table. A gel is applied to the area of the body being studied to help the transducer make secure contact with the body and eliminate air pockets between the transducer and the skin. The technologist then presses the transducer firmly against the skin and sweeps it back and forth over the area to be examined. The test usually takes about 30 minutes.
