Comparison of pudendal and caudal nerve blocks for transrectal prostate biopsy in patients with anorectal disease

Both PuNB and CaNB techniques provided effective analgesia during TRUS-guided prostate biopsy in patients with anorectal disease; however, the caudal nerve block was associated with significantly lower pain scores during the tissue sampling phase, suggesting it may offer superior pain control in this specific patient population. These findings support the consideration of CaNB as a preferable anesthetic approach in cases where conventional methods are insufficient due to anorectal comorbidities.
