Transrectal Ultrasound Biopsy (TRUS)

A TRUS prostate biopsy is normally undertaken if the patient’s PSA is found to be raised and a physical examination via digital rectal examination (DRE) reveals an irregularity in the prostate.  Your GP may perform a DRE or he may refer you to a urologist who will insert a gloved, lubricated finger into the rectum to feel the prostate.  This is one of the tools used to detect early prostate cancer.  When this is done in asymptomatic patients it is called screening.

A TRUS biopsy uses an ultrasound probe inserted into the rectum to provide an ultrasound image of the organs in the pelvis.  It is a very useful tool in assessing the prostate gland.  The ultrasound is utilised to assist in the diagnosis of prostate cancer, benign prostatic hyperplasia (BPH), prostatitis as well as to guide the needle used to take a biopsy of the prostate.  A fine needle is pushed through the wall of the rectum where it meets with the prostate and a biopsy is taken.  The biopsy is then sent to a pathologist for analysis.  The procedure usually takes about 10 minutes; it can be done under local or general anaesthetic.
