Renal Scan

What to expect

The process takes approximately 20 to 30 minutes to complete. The sonographer will ask you to lie down on the examination table. Once you’re comfortable, a gel will be applied to the kidney area, which helps to send sound waves from a probe.

The ultrasound technology encompasses a microphone that gives off sound waves. These waves bounce off the kidney and gallbladder and are picked up by the microphone. A computer is linked to the microphone, allowing your sonographer to see the sound waves on a screen. This gives a clear picture of the internal structure of the kidneys and gallbladder.

When your sonographer examines the quality of the blood flow to your kidneys, it’s normal to hear a ‘swooshing’ sound. You may also feel a little pressure as your sonographer moves the ultrasound probe over the area where your kidneys sit. Once the procedure is over, there’s no recovery period needed.

You will receive a same-day report outlining the findings of your renal ultrasound scan.

Kidney-related symptoms

Several symptoms could suggest your kidney function is impaired including:

• Pain when you pass urine.
• Cloudy urine.
• Breathlessness.
• Itchy skin.
• Swollen ankles, feet and hands (due to water retention).
• Increased need to pee during the night.
• Muscle fatigue.

We may perform a blood test prior to a renal ultrasound scan to identify if these symptoms are associated with kidney problems as opposed to other organs and functions in the body.

Treating renal-related symptoms & health problems

Once we have a picture of your kidney health, your sonographer can advise you on the next steps to treat and manage any problems and symptoms. You may also be sent for further tests.

The main treatments for kidney problems are:

• Medication to control conditions such as high blood pressure and high cholesterol (which can both cause kidney problems).
• Lifestyle changes.
