Doppler ultrasound of the renal arteries

Duplex Doppler ultrasound of the renal arteries is a non-invasive examination to assess the renal arteries, blood flow in the renal arteries and intrarenal flow. The test uses the Doppler effect to assess the speed and direction of blood flow in the blood vessels.

Indications for the examination include:

• diagnosis of hypertension in young people,
• arterial pressure resistant to pharmacological treatment,
• diagnosis of renal artery aneurysms and fistulas.

The test is also performed after kidney transplantation and after stent implantation and balloon angioplasty.

The doppler ultrasound examination of the renal arteries is similar to other ultrasound examinations. The examination is performed through the abdomen – the patient lies down during the examination. The doctor places the head of the device on the patient’s body and moves it around while assessing the image seen on the monitor.

This examination is non-invasive and painless. Once it is completed, you can return to your daily activities straight away.
