Preparation: -Bowel preparation: Purchase one (1) Fleet enemas from the Pharmacy (the Fleets are over the counter). Before your ultrasound test, administer one Fleet enema at home on the morning of your exam. 

Note: A fleet enema is a bottle with 133 ml of liquid in it.  It has a nozzle that is covered with gel. Apply it while lying on your side, inserting the nozzle into the anus and squirting the full content of the bottle into the rectum.  An urge to go to the toilet will follow the application.  Try to wait for 3 to 5 minutes before going to the toilet. After this, your rectum should be completely empty optimizing ultrasound images.
