Renal ultrasound for suspected high blood pressure, etc.

Duplex ultrasound testing of the renal (kidney) arteries is quick, easy and painless and it does not involve radiation. It is also very reliable.

What does the test involve?

Ultrasound is an excellent method for examining the branches of the renal arteries. Doppler ultrasound can be used to detect and measure dilatation (aneurysm) or narrowing (arteriosclerosis) of the arteries.

How does the test work?

The ultrasound transducer is placed on the skin of the abdomen. The transducer produces images (cross-sections) of the arteries. Doppler technology transforms blood flow into both audio and visual signals. The test can be carried out in a matter of minutes. During the test, the patient lies comfortably on his or her back.

Who should be tested?

Patients who are at risk for arterial problems, especially patients with high blood pressure, should have the renal arteries tested at regular intervals. High blood pressure may be caused by narrowing (stenosis) of the renal arteries. After surgery or stent placement, the postoperative results should be monitored regularly. In patients with a pathological condition, regular follow-up may be necessary.

How should I prepare for testing?

Abdominal ultrasound produces more accurate results if the patient has fasted beforehand. This prevents gas from accumulating that may obscure the image. For this reason, abdominal ultrasound appointments should be made for the early morning.

Treating stenosis of the renal arteries

The professional medical associations have drawn up guidelines for this treatment. Stenosis of the renal arteries can be treated very successfully with catheterization. Treatment should take place at a specialized center. Our practice will refer you to the appropriate treatment partner.
