Visual analog pain scores decreased from 3 to 2.7 to 2 at 12- and 24-hours postoperatively. In addition, the total intravenous morphine equivalent dose and PCA pump demand was approximately 13% lower in the PVB group. Furthermore, significant differences (p < 0.001) were found for time to first analgesic administration (120 vs. 20 minutes, PVB and placebo, respectively) and rate of supplemental PO narcotic use (30 vs. 62%, PVB and placebo, respectively). Interestingly, there was a near 20% in the amount of anti-emetics required for the PVB group.
Following the presentation, Dr. Baldea commented that a majority of PCNLs were performed with lower pole access and there was no significant difference in pain outcomes with respect to variable access sites. In addition, a single anesthesiologist supervised and performed a majority (>80%) of the PVBs; however, PVB experience is an important consideration if it is to be utilized for PCNL.
