Randomized Controlled Trial Comparative Study
Comparison of two periprostatic nerve blockade techniques for transrectal ultrasound-guided prostate biopsy: bilateral basal injection and single apical injection.
To investigate the effectiveness of a periprostatic nerve blockade technique that relies on a single apical injection of lidocaine. We compared it with bilateral injections at the base of the prostate to determine the effectiveness of pain control and to compare the technical aspects during transrectal ultrasound-guided prostate biopsy. ⋯ The results of this randomized prospective study suggest that both the single apical injection and the bilateral basal injection techniques are effective in terms of pain prevention during transrectal-ultrasound-guided prostate biopsy. The main advantage of the single apical injection technique is its ease of use and the requirement for one half the amount of local anesthetic agent.
