Randomized Controlled Trial of Single-dose Perioperative Pregabalin in Ureteroscopy.

purposeUreteroscopy is a commonly performed procedure, with postoperative pain that can lead to revisits and opioid prescribing. Perioperative gabapentinoids have shown promise in decreasing pain and opioid use. We hypothesized that single-dose perioperative pregabalin would be safe and efficacious for decreasing pain after ureteroscopy. MATERIALS AND

methodsThis was an Institutional Review Board-approved and registered blinded, placebo-controlled trial conducted at a single institution. Patients undergoing ureteroscopy without histories that would limit use of opioids, gabapentinoids, and nonsteroidal medications were enrolled. Either 300 mg pregabalin or placebo was administered 1 hour before ureteroscopy. Pain was assessed using a visual analogue scale before administration and 1 hour after surgery. Clinical factors, pain scores, a proxy for cognition, patient satisfaction, and opioid prescribing were assessed in the first 30 postoperative days.

resultsA total of 118 patients were enrolled over a 2-year period. Patients who received pregabalin were younger than those who received placebo (median of 44 years vs 57). Postoperative pain scores were higher in those who received pregabalin (3.7 vs 2.0,

conclusionsIn this trial evaluating the efficacy of single-dose perioperative pregabalin in ureteroscopy, pregabalin did not decrease postoperative pain when compared to placebo. Urologists should not routinely use this adjunctive medication in ureteroscopy, as it is unlikely to provide benefit.
