Prostate Ultrasound with Biopsy
During a prostate ultrasound, a probe about the size of a finger is placed a short distance into the
rectum. This probe creates images of the prostate gland. The probe helps your doctor see the
size of your prostate and detect any abnormal growths.
During a prostate biopsy, ultrasound helps to guide the small needle through the rectum into
areas of the prostate where abnormal tissues may be detected. The needle is used to collect tissue
samples from these areas.
While lying on your left side, with your knees drawn up, the ultrasound probe will be placed into
the rectum and the biopsies are taken. You may feel pressure as the samples are taken. It takes
about 5 minutes to get the samples. After the biopsy is done, you may need to stay until you are
able to urinate.
