Introduction: To determine whether a combination of the long acting local anesthetic, bupivacaine, and lidocaine is better than lidocaine alone in the long-term pain control, which is a short-acting anesthetic.
Materials and methods: In group 1, periprostatic nerve block was applied to both neurovascular areas with 2% lidocaine (5 ml) in an isotonic solution (5 ml). In group 2, the combination of 2% lidocaine (5 ml) and 5mg/ml bupivacaine (5 ml) was used for the PPNB.
Results: In the first 30 minutes the mean VAS scores of groups 1 and 2 were 2.1 ± 0.2 and 1.2 ± 0.1, respectively (p = 0.002). VAS scores of group II determined at 1, 2, 4, 6, and 8 hours after the biopsy were significantly lower since it was (p < 0.05).
Conclusion: While periprostatic nerve block for late phase pain control, applying a combination of a long-acting local anesthetic, such as bupivacaine, is effective in terms of pain control and patient comfort.
