Prostate Ultrasound

prostate ultrasound

What is it?

Prostate Ultrasound is a minimally invasive procedure that is done trans rectally (through the rectum). It uses high-frequency sound waves to produce a picture of your prostate gland.

It does not use x-ray or other radiation. And, unlike radiation, standard diagnostic ultrasound has no know side effects. This type of imaging is also in "real time". That means you can see the movement of the prostate gland as well as the blood flowing through the prostate. It is a great aid that helps physicians diagnose the condition of the prostate gland.

Safe and Non-Invasive with Superior Results

Ultrasound imaging is unlike prostate biopsy (needle biopsy), which is highly invasive and can cause more harm than good. Needle biopsy can release normally contained cancer cells into the blood stream where they can then settle into bones and other organs to cause further cancers.

Ultrasound does not have that associated deadly risk.

And, unlike x-rays, Prostate Ultrasound causes no known health problems and can be repeated as often as necessary.

It is also superior to x-ray. It gives a clear picture of soft tissues which do not show up well on x-ray film.

Ultrasound is also much less expensive than an MRI.

What It Shows

Transrectal ultrasound imaging of the gland is used to detect abnormalities within it such as:

  • Tumors
  • Enlargement
  • Male infertility

Physicians may want to see an ultrasound image if they feel a lump during a digital rectal exam or if the PSA level was high.


The procedure for ultrasound imaging here is very simple.

Usually you will be given an enema shortly before the test to empty out your bowel. Also you will probably be asked to drink many glasses of water so that your bladder will be full. A full bladder helps to view the prostate.

Then a covered lubricated instrument called a transducer will be inserted into your rectum. Inaudible high frequency sound waves will be emitted from this.

The imaging will usually be performed from different angles to give the best possible view of the gland. The entire exam usually only lasts about 20 minutes.

The Way It Works

The way it works is just like sonar on a ship. The sound waves are sent out from the transducer and they bounce back from the objects (organs) they hit. Like an echo. These "echoes" come back like a mirror image, but in sound. The transducer then also records these "echoes".

A computer then translates these sound wave "echoes" into pictures immediately visible on the computer screen.

The pictures are in "real time". That means, with prostate ultrasound, you can actually see your gland as it is functioning in that moment!

The entire video is usually videotaped so the physician can use it later to diagnose the condition of the gland.

This is the same procedure used in a woman's vagina to view a developing baby.


Physicians who use Prostate Ultrasound imaging will typically call for a needle biopsy if any tumors are found. This may or may not be something you wish to do when you know the dangerous and possibly life threatening risks connected to a needle biopsy.

Prostate Ultrasound has many advantages over a needle biopsy when diagnosing tumors.

In any case, Prostate Ultrasound seems to be an effective and relatively harmless way to get a good look at this gland. And, unlike x-ray or biopsy, it can safely be used repeatedly.
