Summary
Patients at risk for having prostate cancer usually undergo a biopsy of their prostate. This
is most often done in the private urology office. Recent studies have suggested that
injection of local anesthesia (lidocaine) near the nerves of the prostate will improve pain
sensation during the biopsy procedure. Local anesthesia can be given through a separate
needle through the rectal probe just prior to biopsy. However, many urologists to date
perform their biopsies without anesthesia. Some claim that the needle used for anesthesia
causes pain itself. Others claim that the pain is so minimal that the additional use of
lidocaine (and extra time) is not necessary. We plan to reexamine the use of lidocaine and
perform the first study where each patient will receive lidocaine and placebo on separate
sides of their prostate.
