Prostate ultrasound is a simple diagnostic procedure which is done in the urologist's office. It is commonly performed to investigate male infertility, pain during ejaculation, blood in the semen, or to measure the size and shape of the prostate prior to treatment of an enlarged prostate (BPH). If a patient has an elevated PSA test or an abnormal prostate examination the prostate ultrasound and biopsy are performed to rule out prostate cancer.
Prostate ultrasound uses an ultrasound probe which is inserted into the rectum the same way a finger is used to examine the prostate. The ultrsound probe uses sound waves to take a detailed picture of the size and shape of the prostate. There may be a small amount of discomfort when the probe is inserted, but usually not much more than with a finger exam. No biopsies are performed with prostate ultrasound.
Transrectal prostate ultrasound
If you move your bowels regularly then no special preparation is necessary for prostate ultrasound. If you do not have a bowel movement daily then a gentle laxative or fleets enema would be a good idea 1-2 hours before your appointment.
There are no signigicant risks associated with prostate ultrasound. Prostate ultrasound is not a test to diagnose prostate cancer, this requires a prostate needle biopsy.
