Transrectal prostate biopsy is a common ambulatory procedure that can result in pain and anxiety for some men. Low-dose, adjustable nitrous oxide is increasingly being used to improve experience of care for patients undergoing painful procedures. This study seeks to evaluate the efficacy and safety of low dose (<45%) nitrous oxide, which has not been previously established for transrectal prostate biopsies.
