Recommendations for the user prostate biopsy

What is it? 

A prostate biopsy is a procedure to remove samples of suspicious tissue from the prostate. The prostate is a small, walnut-shaped gland in men that sits just below the bladder and produces a fluid that nourishes and transports sperm. It is performed to examine it and detect or not the presence of any disease​.

How the exam is done

There are three main ways to perform a prostate biopsy. 

Transrectal prostate biopsy- through the rectum. This is the most common method.

  • You will be lying on your side with your knees bent and will remain still.

  • A finger-sized ultrasound probe will be inserted into your rectum, which allows images of the prostate to be seen, and an anesthetic will be injected around the prostate. You may feel some discomfort or pressure.

  • Then, using ultrasound to guide the biopsy needle, the needle is inserted into the prostate to take the sample. This can cause a brief stinging sensation.

  • Approximately 10 to 18 samples are taken. The samples will be sent to the laboratory for examination.

  • The entire procedure will take approximately 10 minutes.


Other methods are used to perform prostate biopsies; however, they are not used very often. These include:


transurethral - through the urethra.

  • An anesthetic is given to numb you so you don't feel pain.

  • A flexible tube with a camera at the end (cystoscope) is inserted through the opening of the urethra at the tip of the penis.

  • Tissue samples are taken from the prostate through the cystoscope.

Perineal - through the perineum (the skin between the anus and the scrotum).

  • An anesthetic is given to numb you so you don't feel pain.

  • A needle is inserted into the perineum to collect prostate tissue.
