OBJECTIVES: To evaluate the effect of periprostatic infiltration with local anesthesia on the level of discomfort associated with transrectal ultrasound-guided needle biopsy of the prostate. Transrectal ultrasound-guided needle biopsy of the prostate is the standard procedure to diagnose prostate cancer. METHODS: A prospective, randomized, double-blind study was performed on 100 men referred for biopsy of the prostate. Fifty subjects were randomized to periprostatic injection of 10 mL of 2% lidocaine solution without epinephrine, and 50 were randomized to injection of placebo (10 mL of 0.9% NaCl). Each subject completed three 10-point visual analog scales for pain after a series of 15 needle biopsies. Pain was rated during the biopsy, diagnostic investigation, and injection of lidocaine. RESULTS: Patients who received local anesthesia had significantly lower visual analog scale scores compared with the group without lidocaine during the biopsy (mean score 0.76 versus 3.62, P <0.001) and diagnostic examination (mean score 1.08 versus 1.86, P = 0.025). Lidocaine injection caused no adverse effects. CONCLUSIONS: Periprostatic injection of lidocaine represents a simple and safe procedure that significantly reduces discomfort during probe manipulation and biopsy. We recommend this procedure in men undergoingtransrectal ultrasound-guided prostate biopsy.
