Detailed Description

Postoperative pain continues to be a significant clinical problem. Use of perioperative adjuvants has improved postoperative pain control. The GABA-B receptor agonist, baclofen, is an appropriate drug to trial as such an analgesic adjuvant. Therefore, the investigators will conduct a study designed to determine whether or not a single, oral dose of baclofen given to patients undergoing kidney stone surgery will reduce postoperative opioid requirements measured in the first 24 hours following surgery.
