Transrectal ultrasound scan (TRUS) of the prostate

This procedure uses ultrasound to produce cross-sectional images of the prostate. Different tissues reflect the ultrasound waves emitted by the ultrasound probe (transducer) in different ways. The information this generates is used to create 2-dimensional images which are displayed on a screen. In TRUS, the probe is inserted into the rectum and the size, shape and composition of the prostate assessed.
This procedure is very good at evaluating the size and shape of the prostate. It is of only limited value for detecting prostate cancer, as small cancers in particular do not look very different from normal healthy prostate tissue on an ultrasound scan.

Shear wave elastography of the prostate

This is an additional procedure performed in tandem with transrectal ultrasound, which is carried out in the same way.

This procedure uses a computer to measure the speed of ultrasound waves, providing information on tissue stiffness. This allows better and more accurate identification and visualisation of any changes in the prostate, particularly where prostate cancer is suspected. Elastography is particularly useful for identifying areas of the prostate for biopsy.

We offer this procedure as part of our urology consultation service.
