Renal Scan
Kidney Ultrasound

- 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.

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.
