specializes in men's genital and urinary problems (urologist) in
the doctor's office, a day surgery clinic, or a hospital operating room.
Before your prostate biopsy, you may be given
antibiotics to prevent infection. You may be asked to
take off all of your clothes and put on a hospital gown.
Transrectal ultrasound (TRUS) is commonly used to
guide the placement of the needle during a prostate biopsy.
Through the rectum (transrectal biopsy)
positions are possible for this method. You may be asked to kneel, lie on your
side, or lie on your back with your feet resting in stirrups. Your doctor may
inject a local anesthetic around the prostate gland before the biopsy is

and removes a tissue sample. Between 6 and 12 samples are taken from different
areas of the prostate.

local anesthesia may be used.
scope (cystoscope) is inserted into your urethra. It allows
your doctor to look directly at the prostate gland. A cutting loop is passed
through the cystoscope to remove small pieces of prostate tissue.
A transurethral biopsy usually takes about 30 to 45 minutes.
Through the perineum (transperineal biopsy)
Transperineal biopsy is not done as commonly as transrectal or
transurethral biopsy. You will lie on an examining table either on your side or
on your back with your knees bent. General or local anesthesia may be
