Abstract/OtherAbstract:
OBJECTIVE: Transrectal ultrasound (TRUS)-guided prostate needle biopsy is the standard procedure to diagnose prostate cancer. It can be associated with significant discomfort and pain. We evaluated if periprostatic infiltration with local anesthetic reduces this discomfort. MATERIAL AND METHODS: 72 patients underwent TRUS-guided prostate needle biopsy. All patients had 12 cores, with four prostatic zones of biopsies. In 25 consecutive patients (G1) with a median prostate size of 47 cc, no anesthesia was given; while in 47 sequential patients (G2) with a median prostate size of 50 cc, 2 ml of 2% lidocaine was infiltrated in the periprostatic area around the neurovascular bundle using 20-cm-long, 22-gauge needle on both sides as guided by color Doppler. Biopsies were performed in standard fashion. Discomfort was graded on a scale from 0 to 10 with 0 meaning no discomfort, 1-3 mild, 4-6 moderate, and 7-10 severe. RESULTS: 12/25 (48%) of G1 patients reported no discomfort compared to 70% in G2 (P=.025). Mild discomfort was reported in 5/25 (20%) patients of G1 and 9/47 (19%) patients of G2. Moderate or severe discomfort was reported in 8/25 (32%) patients and 5/47 (11%) patients in G2 (P=.039). Prostate size did not affect degree of discomfort within each group and between both subgroups. No adverse reactions were observed secondary to lidocaine infiltration. CONCLUSION: Periprostatic infiltration with local anesthesia at the time of TRUS-guided prostate needle biopsy significantly reduces discomfort. It is easy to perform, safe, and should be considered in all patients irrespective of the prostate size.
