Lithotripsy, Nephrolithiasis, Analgesia


Introduction: Nephrolithiasis is a disease characterized by the formation of a crystalline mass in the renal excretory pathways, whose treatment was revolutionized with the implementation of shock wave lithotripsy (ESWL), which in a non-invasive manner, has good effectiveness and morbidity. The pain experienced during a ESWL is directly related to worse post-surgical morbidity. However, there are no guidelines for pain management during the procedure. Objective: To assess pain in patients with ESWL with different models of preemptive analgesia. Methods: This is a non-randomized clinical trial. A total of 30 patients were divided into three groups, group A with 30g of 2% lidocaine gel 30 minutes before the procedure; group B, 550 mg of sodium naproxen was administered orally 45 minutes before the procedure; and group C both associated. Results: There was an average of maximum pain of 6 in the group of patients who received naproxen sodium and 2% lidocaine gel, in contrast to those who did only local analgesia (6.8) or oral (6.2) only. One patient required supplemental analgesia in group A, but none did in the other groups. The average wave was 2492.2 ± 320,62 for group A, 2507.4 ± 242.23 for group B and 2434 ± 227.25 for group C. Statistically, there was no difference about energy average be-tween groups. Conclusion: There was no difference between the models of analgesia used.
