Trans-rectal Ultrasound Guided Biopsy of the Prostate (TRUS Prostate)

Where is the prostate gland?

The prostate is a walnut-size gland, situated below the bladder. It completely surrounds the urethra. Its main function is to continuously produce a thin, fluid.

Why am I having this test?

Prostate biopsy is performed if there is a lump in the prostate or if the level of Prostate Specific Antigen (PSA) is high from your blood test. The biopsy will determine if the findings are significant and therefore if any treatment is needed.

How do I prepare for this test?

There is no need to fast for this procedure

Cease Aspirin/warfarin 7 days prior

You will be given a script for six (6) antibiotic tablets; these should be taken one hour prior to eating. Start these the day before the procedure, taking one antibiotic in the morning and one in the evening.

Your bowel needs to be emptied prior to the procedure.

You will need to use the suppository 2 hours prior to the procedure (even if you have opened your bowels naturally).
