Objectives To assess the efficacy of local anesthetic cream compared with nalufin for pain control during extracorporeal shock wave lithotripsy (SWL). Background Local anesthetic is a method of pain control for various procedures. Patients and methods This is a prospective randomized study of patients diagnosed with renal or ureteric stones and should receive SWL as treatment. A total of 80 patients were divided into two groups, with 40 patients each: eutectic mixture of local anesthetics (EMLA) group (group A) received EMLA cream and received nalufin intravenous injection on demand if pain was intolerable, and nalufin group (group B) received nalufin intravenous injection before SWL. Data were coded and entered to the International Business Machines Company for Statistical Package for Social Science, version 23. Results Group A tolerated more intense pain (P = 0.027), group B received more doses of nalufin (P = 0.000), patients of group B expressed more intense feeling of pain by face scale (P = 0.011), numerical pain score was more for the group B (P = 0.004), group A patients were more satisfied (P = 0.030), group A had less time in the hospital stay (P = 0.000), and group B experienced more percentage of complications (P = 0.000). Conclusion Using EMLA during SWL was successful for pain control and patient comfort and significantly reduced use of nalufin and reduced complications and hospital stay.
