Abstract
Objective: To assess the effectiveness and safety of caudal block on the pain associated with digital guided transrectal Tru-Cut biopsy of the prostate.
Subjects and Methods: Over a two year period, from July 2013 to June 2015, a cross-section of one hundred and forty men undergoing digital guided transrectal prostate biopsy under caudal block were recruited into the study. 15 ml 1% lignocaine was injected for caudal block. Pain scores, anal sphincter tone and patient satisfaction were assessed and complications recorded.
Results: The mean ± SD (min-max) biopsy time was 12.1 (8-16) minutes. The mean ± SD (min-max) pain score on visual analogue scale (VAS) was 1.2±1.6 and 85% of patients reported excellent satisfaction. There was no statistical significance between pain score and age (P= 0.185) or the number of biopsies taken (P= 0.164). Malignancy was found in 37.1% of patients.
Conclusion: Caudal block is an effective and safe method of anesthesia for digital guided transrectal prostate biopsy.
