During a prostate biopsy, a needle is guided through the rectum into the prostate. Although
patients are given antibiotics before the biopsy, there is still a risk of bacteria getting
from the rectum into the bladder, prostate and bloodstream during the biopsy. For most
surgical procedures, the surgical field is cleaned with antiseptic solution, but this is not
common practice for prostate biopsies. In this study patients undergoing prostate biopsy will
be randomly assigned to either receive an antiseptic preparation of the rectum or no
preparation prior to biopsy, and the rate of infection after the biopsy will be determined.
