• The technician could ask you to urinate to clear your bladder just before the procedure.

Procedure

You'll probably be asked to lie on your side with your knees bent toward your chest during the test. The ultrasonic probe is covered and lubricated by the doctor. The probe, which is about a finger's width, is then inserted into the rectum by the physician. When the transducer is in place, you can experience pressure or a feeling of fullness in the rectum.
