You must have a full bladder for the test. Do not empty your bladder until after the ultrasound.
Description of Test
You will lie on a table. A gel will be put 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. It 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 images are examined. A photograph of them may be made.
Your images will be viewed by your doctor or radiologist. Problems in your organs may be detected. Blockages may be seen in the ureters. In this case, more tests may be done to find the exact problem and cause.
