What do I need to know about a bladder ultrasound?
A bladder ultrasound is a test that uses sound waves to look at your bladder. It can also help your healthcare provider see how much urine is left in your bladder after you urinate. A bladder ultrasound does not expose you to radiation.
How do I prepare for a bladder ultrasound?
Your healthcare provider will talk to you about the test. You will need to drink several glasses of water before your test. After you drink the water, do not urinate until you are told it is okay to do so.
What will happen during a bladder ultrasound?
You will lie on a table. Your healthcare provider will put gel on your lower abdomen. A device called a transducer will be moved over your lower abdomen. The transducer uses sound waves to make images of your bladder. Your provider will ask you to urinate. Then more images of your bladder will be taken when it is empty.
