Abstract
Purpose:
To determine the efficacy of periprostatic nerve block (PPNB) for control of transrectal ultrasound (TRUS)‐guided multicore prostate biopsy‐related pain.
Methods:
A total of 106 cases with suspicion of prostate cancer underwent TRUS‐guided multicore prostate biopsy under local anesthesia using a total of 10 ml of 1% lidocaine for each patient. Lidocaine was injected around the neurovascular bundle at the base of the prostate just lateral to the seminal vesicle‐prostate junction. The pain score was assessed using visual analog pain score from 0 to 10. All patients were questioned for whether they would accept repeat biopsy or not, if necessary.
Results:
Pain score ranged from 0 to 5 (mean: 1.4). Thirty‐five percent (37/106) of patients reported a score of 0, whereas 17% (18/106), 32% (34/106), 8.4% (9/106), 6.7% (7/106), 0.9% (1/106) reported pain scores of 1, 2, 3, 4, and 5, respectively. There were no pain scores of 6–10. Answers for the question “would you accept repeat biopsy or not, if necessary?” was “yes” for 82% (87/106) of the patients.
Conclusions:
PPNB prior to multi‐core TRUS‐guided prostate biopsy is an easy, safe, and effective technique for the control of procedure‐related pain. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound, 2011
