Randomized Controlled TrialSubcutaneous bupivacaine infiltration and postoperative pain perception after percutaneous nephrolithotomy.
Recent studies have shown a significant decrease in patient reported pain scores when the nephrostomy tube size is decreased from 22 to 10Fr. We hypothesize that patient reported pain and narcotic use could be further decreased for patients with post-percutaneous nephrolithotomy nephrostomy tubes if the incision is infiltrated with a local anesthetic. ⋯ In this preliminary pilot study no significant differences in patient reported pain scores were observed. However, a trend toward decreased postoperative narcotic use was seen in patients receiving subcutaneous Marcaine administration around the nephrostomy tube tract. Further studies are warranted to define additional measures to reduce discomfort in those requiring nephrostomy tube drainage following percutaneous nephrolithotomy.
