Transrectal prostate ultrasound

"An elevated PSA value in itself is not a diagnosis of prostate cancer, since it is also associated with other pathologies such as benign prostatic hyperplasia or prostatitis".


Transrectal ultrasound is a test that uses ultrasound and not X-rays.

Multiple studies have shown that these ultrasounds are harmless and can be used safely in patients who need a diagnosis of prostate problems such as prostate cancer or benign prostatic hyperplasia.

In certain cases, an ultrasound or CT scan may be indicated to obtain the diagnosis. However, the specialist will indicate the most appropriate type of study.

How is transrectal prostate ultrasound performed?

With the person lying on their side and their legs bent, a cover is placed over the ultrasound device (transducer) and inserted into the rectum. Images are taken at different angles, and measurements are taken to calculate the weight of the prostate and other possible morphological findings.

If suspicious images appear, a needle biopsy can be taken in the same scan. By seeing the image of the prostate live, it is possible to direct it very well and take the biopsy of the most appropriate area.

The study can take about 20 minutes or more if the biopsy is taken. No harm is done, just a little bit when the biopsy is taken and the patient can leave on his own and go home without problems. 

An enema is indicated before the study is performed to allow the rectum to be clean when the ultrasound emitter is introduced.

A full bladder is also required, then several glasses of water should be drunk prior to the exploration.
