Why Have a Renal Ultrasound?

Renal ultrasounds are usually used to assess the bladder, kidneys and other related structures. The real time images created by the ultrasound machine can identify stones, tumours and other urinary disorders. Ultrasounds are completely safe and cause no pain or discomfort and so are usually the first tests to be taken to understand why symptoms are being experienced.

Who performs the examination?

Ultrasounds are performed by specialist staff called Sonographers. All X-Ray & Imaging Sonographers have extensive clinical ultrasound experience.

What happens during the examination?

In most cases you will be asked to remove any clothing that obstructs your pelvic area and wear one of the gowns provided. Once changed, the Sonographer will apply a cool gel to your skin in the area being examined. Once this has been applied, the Sonographer will pass a marker shaped instrument called a transducer over the gel creating images of internal organs that appear on a screen in front of you. This may take several minutes. Once the Sonographer is happy with the accuracy of the images the examination is over. The images are then assessed and reported on by a radiologist, this report will be sent straight to your doctor. Once you have your films you are finished. Remember to take your films to your next doctor’s appointment. In most cases the whole process takes less than an hour from entering the building and leaving with your results.

What does it show?

Renal ultrasounds are very good at showing the presence of kidney stones, renal blockages, cysts and tumours. This can provide important information as to why possible symptoms exist and kidney function.
