A prostate or rectal ultrasound is an imaging test that uses sound waves to look at your prostate or your rectum.
The healthcare provider uses a device called a transducer to make the images of your prostate or rectum. The transducer sends out sound waves that bounce off your organs and other structures. The sound waves are too high-pitched for you to hear. The transducer then picks up the bounced sound waves. These are made into pictures of your organs.
Your provider can add another device called a Doppler probe to the transducer. This probe lets your provider hear the sound waves the transducer sends out. He or she can hear how fast blood is flowing through a blood vessel and in which direction it is flowing. No sound or a faint sound may mean that you have a blockage in the flow.
A prostate/rectal ultrasound may be used to check the size, location, and shape of the prostate gland and nearby structures. It may be used to look at the prostate gland for signs of cancer. It’s often the next step after a finding of elevated prostate-specific antigen (PSA) during a blood test. Prostate/rectal ultrasound may be used to stage and watch treatment of rectal cancer. It is also used to look at the rectum for other problems.
Your healthcare provider may also use a prostate/rectal ultrasound to help place a needle to take a tissue sample (biopsy). Or he or she may use it to help place radiation "seeds" used to treat prostate cancer.
Your provider may also use the test to see how well blood is flowing to the prostate or find masses.
Your provider may have other reasons to recommend a prostate/rectal ultrasound.
An ultrasound has no risk from radiation. Most people have no discomfort from the transducer moving across the skin.
Tell your healthcare provider if you are allergic to latex. The probe is placed in a latex covering before it is put into the rectum.
You may have risks depending on your specific health condition. Be sure to talk with your provider about any concerns you have before the procedure.
Too much stool in the rectum may make the test less accurate.
You may have a prostate/rectal ultrasound done as an outpatient or during a hospital stay. The way the test is done may vary depending on your condition and your healthcare provider's practices.
Generally, a prostate/rectal ultrasound follows this process:
A prostate/rectal ultrasound is not painful. But you may have some discomfort from having to remain still during the test. The gel will also feel cool and wet. The technologist will use all possible comfort measures and do the scan as quickly as possible to minimize any discomfort.
Before you agree to the test or the procedure make sure you know:
