Randomized Controlled Trial Clinical Trial
Analgesia during extracorporeal shock wave lithotripsy using the Medstone STS lithotriptor: a randomized prospective study.
To investigate and compare the effectiveness of three analgesic protocols for pain management during extracorporeal shock wave lithotripsy (ESWL) in a prospective, randomized clinical trial. ⋯ The use of KT was safe and effective for premedication before ESWL; patients receiving KT before ESWL reported lower pain scores and required less supplemental analgesia requirement than those who received MS or Emla; however, the differences were not statistically significant. Patients receiving Emla recorded the highest pain scores. Patients with ureteral stents had lower pain scores and required less supplemental analgesia.
