Why does my bladder have to be full for an ultrasound?
Since sound waves travel easily through fluid, a full bladder allows them to penetrate deep into the pelvis to image the cervix on an obstetrical exam and the pelvic organs on a regular pelvic ultrasound.
How do you prepare for a bladder ultrasound?
Preparation. Usually, you don’t have to do anything special to prepare for a bladder ultrasound, although the doctor may ask that your child drink lots of fluids before the exam so that he or she arrives with a full bladder.
What if I pee before my ultrasound?
Don’t urinate (pee) before your ultrasound. Having a full bladder will make it easier to see your uterus and ovaries. If close-up views of the lining of your uterus and your ovaries are needed, you may have a transvaginal ultrasound after your pelvic ultrasound.
What happens if you don’t have a full bladder for an ultrasound?
A full bladder in this case would not only distort the image of the uterus but it will also be uncomfortable for the woman. The bladder for this ultrasound needs to be empty. An empty or full bladder can mean the difference in how accurate the ultrasound imaging is.
