Opioid-free percutaneous nephrolithotomy: an initial experience.

The opioid epidemic in the United States is an ongoing public health crisis that is in part fueled by excessive prescribing by physicians. Percutaneous nephrolithotomy (PCNL) is a procedure that conventionally involves opioid prescriptions for adequate post-operative pain control. We aimed to evaluate the feasibility of a non-opioid pain regimen by evaluating post-operative outcomes in PCNL patients discharged without opioids. As a quality improvement measure to reduce opioid consumption our department began routinely prescribing oral ketorolac instead of oxycodone-acetaminophen for pain control after PCNL. We retrospectively compared patients undergoing PCNL who had received ketorolac prescriptions (NSAID) to those who received oxycodone-acetaminophen prescriptions (NARC). Demographic, operative, and post-operative factors were obtained and compared in both groups. Peri-operative factors and demographics were compared using either Chi-squared tests, Mann-Whitney U tests. Surgical outcomes were compared between the two groups using Chi-squared tests and Fisher's exact tests. Multivariate logistic regression analysis was performed to determine whether ketorolac use was an independent predictor of post-surgical pain-related encounters. Primary outcome was unplanned pain-related healthcare encounters inclusive of office phone calls, unscheduled office visits, and emergency department (ED) visits. Secondary outcome measures were non-pain-related healthcare encounters, hospital readmissions, pain-related rescue medications prescribed, and post-op complications. There were similar demographics and peri-operative characteristics amongst patients in both cohorts. There was no significant difference identified between NSAID and NARC regarding unplanned pain-related encounters (8/70, 11.4% vs. 10/70, 14.3%, p = 0.614). However, NARC experienced more unplanned phone calls (42, 60% vs. 24, 34.3%, p = 0.004). Multivariate analysis revealed only prior stone surgery was predictive of pain-related encounters after PCNL (p = 0.035). Our results show that there were no significant differences in pain-related encounters between those who received ketorolac and oxycodone-acetaminophen following PCNL. A non-opioid pathway may mitigate the potential risk associated with opioid prescription without compromising analgesia. Prospective comparative studies are warranted to confirm feasibility.
