the prostate biopsy what to expect

You will be asked to lie on your side with your knees pulled up to your chest. You might be asked to lie on your stomach. After cleaning the area and applying gel, your doctor will gently insert a thin ultrasound probe into your rectum.

Transrectal ultrasonography uses sound waves to create images of your prostate. Your doctor will use the images to identify the area that needs to be numbed with an injection to reduce discomfort associated with the biopsy. The ultrasound images are also used to guide the prostate biopsy needle into place.

Once the area is numbed and the biopsy device is situated, your doctor will retrieve thin, cylindrical sections of tissue with a spring-propelled needle. The procedure typically causes a very brief uncomfortable sensation each time the spring-loaded needle takes a sample.

Your doctor may target a suspicious area to biopsy or may take samples from several places in your prostate. Generally, 10 to 12 tissue samples are taken. The entire procedure usually takes about 10 minutes.
