A transrectal ultrasound is used as a diagnostic or screening tool as a way to take images and assess organs and tissues inside the body. The procedure may also be referred to as a prostate sonogram or an endorectal ultrasound.
Preparation
In the days leading up to the ultrasound, make sure your healthcare provider is aware of any allergies you have to medication. It’s especially important to notify them of allergies you have to antibiotics.
Depending on the reason for your test, you may be asked to follow certain instructions to prepare for the exam.
What to Expect
On the day of the ultrasound, wear loose-fitting, comfortable clothing. You’ll likely be asked to remove all or part of your clothing, and you may be asked to wear a gown. Additionally, your healthcare provider might ask you to urinate so that you have an empty bladder before the test.
