Transrectal prostate ultrasound (TRUS)

How is the examination performed?

• The examination is performed in a lying position.
• A thin ultrasound probe is inserted into the rectum, covered with a protective sheath and lubricant.
• The probe transmits sound waves that create a detailed image of the prostate.

The examination usually takes 5–10 minutes.

It is not a painful procedure, but it may cause a mild feeling of pressure.

What is important to know before the examination?

Usually, fasting is not required.

Inform your doctor if you have:

• rectal diseases
• hemorrhoids in the acute phase
• recent surgery in the rectal area

If the examination is performed together with a biopsy, you will receive separate detailed instructions.

What sensations may occur during the examination?

• Mild pressure or fullness sensation
• Short-term discomfort when inserting the probe

Most patients describe the examination as uncomfortable but not painful.

What to expect after the examination?

If only ultrasound is performed (without biopsy):

• You may continue normal activities immediately
• No recovery time is needed
• No restrictions are required

If a biopsy is performed during the examination, the doctor will give separate instructions.
