Caffeine is a diuretic it causes cells to loose water. If you are a regular caffeine drinker, however, this amount of water might not be enough to fill your bladder.
#PELVIC SONOGRAM FULL#
For well-hydrated people, this amount is sufficient to produce a full bladder. The usual bladder prep for this procedure is to drink three 8-oz glasses of water 45 minutes to 1 hour before the start of the exam. Since a full bladder enhances the transabdominal pelvic image, you will need to make sure your bladder is full for this exam. A full bladder allows the sound waves to pass through the abdominal cavity without losing any significant strength, resulting in a clearer picture. As the name implies, the sound waves are beamed through the patient’s lower abdomen in an effort to see the uterus, ovaries, and surrounding areas in one big picture. The transabdominal ultrasound exam provides the “big picture” of the pelvic organs, such as their size, shape, location, and orientation while displaying the presence of any abnormalities. Knowing the purpose of the exam and understanding the preparation and procedure for the first portion will help you to navigate the procedure smoothly. A pelvic ultrasound usually consists of two parts: the transabdominal exam and the transvaginal exam. Unlike other diagnostic tools, ultrasound uses sound waves instead of radiation to produce images of the human body and is particularly useful in evaluating soft tissues, organs, and fluids. If your doctor has ordered a pelvic ultrasound, she is interested in evaluating your uterus, ovaries, and bladder for abnormalities.
