- Rule out renal & bladder conditions
- Diagnose kidney problems
- Detect signs of chronic kidney disease
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.
Several symptoms could suggest your kidney function is impaired including:
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.
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:
Very little preparation is needed before the ultrasound. You will need to drink 700ml water an hour or more before the procedure. No fasting is necessary.
We may recommend a renal ultrasound if we believe you are suffering from the following:
Yes. As kidney failure changes the shape and size of the kidneys, the scan will identify advanced damage and kidney failure immediately. When both kidneys are less than 6cm in length, this is classed as kidney failure.
