Periprostatic local anesthesia eliminates pain of office-based transrectal prostate biopsy.
Up to 96% of patient who undergo prostate biopsy report pain. We performed periprostatic local anesthesia injection in an effort to improve patient acceptance of prostate biopsy. Sixty patients were randomized to receive either local injection of lidocaine in the periprostatic nerves or no anesthetic. Lidocaine was injected through a 7-inch spinal needle placed through a transrectal ultrasound biopsy guide. Ten-core biopsies were immediately performed. Following biopsy, all patients gave a Visual Analog Scale (VAS) assessment of their pain experienced during biopsy.A majority of patients reported Visual Analog Scale (VAS) scores in the moderate (28.6%) or severe (28.6%) ranges unless local anesthesia was given. Only one of 27 patients (3.7%) receiving local anesthetic reported moderate pain, and none reported severe pain. Mean VAS pain scores were 1.4 in the anesthetic group and 4.5 in the control group (P<0.0001). No difficulty was encountered from scarring in the five patients who underwent nerve spring radical retropubic prostatectomy following local anesthetic injection. Periprostatic injection of local anesthetic essentially eliminates pain from prostate biopsy. Nerve-sparing radical retropubic prostatectomy is not more difficult as a result.
