You will lie on a table. Your doctor will put a gel on your belly over your bladder and kidneys. The gel helps the sound waves travel between the machine and your body.
The ultrasound machine has a hand-held instrument called a transducer, which looks like a microphone or wand. The transducer is pushed against your skin where the gel was applied. The transducer sends sound waves into your body. The waves bounce off your internal organs and echo back to the transducer. The echoes are converted into images that are shown on a screen. The doctor examines the images. He may make a photograph of them.
The gel will be wiped from your belly.
A radiologist will look at the images to make sure everything appears normal.
If your doctor or radiologist detects any problems with your organs or blockage in any of the tubes, more tests may be done to find the exact problem and cause. The doctor may also decide that the renal ultrasound provides enough information to make up a treatment plan for you.
Call your doctor if you have any questions about the test, your condition, or your test results.
