With this method, after you pee, the nurse will hold the ultrasound wand against your belly. Pictures of your bladder will show up on a monitor, and your doctor will use them to measure the urine there.
This method has a few advantages over the catheter method.
But an ultrasound might not work for some people. For example, if you’re obese, the machine may not be able to get clear pictures of your bladder.
- Because nothing goes inside your body, there’s no chance of injury or infection.
- The sound waves are painless.
- The nurse doesn’t need to see your private parts.
- It’s safer for children and doesn’t stress them out as much.
