Transrectal ultrasound guided biopsy of the prostate (TRUS) is a procedure where tissue samples are taken from the prostate gland via an ultrasound probe that has been inserted through the rectum.
This test is either performed under local or general anaesthetic.
The procedure is done to assess for the presence of prostate cancer. The indications for the procedure are an abnormal PSA (prostate specific antigen) or alternatively an abnormal DRE (digital rectal examination).
The procedure usually takes around 15 minutes to perform. Tissue samples are sent to a pathology laboratory where they are examined under a microscope to assess for the presence of prostate cancer. Results are usually available within 2 weeks.
