Urological surgery, particularly genitourinary surgery, is associated with considerable postoperative pain in children [1]. In the past little attention was paid to the management of pain in the pediatric age group. This was due mainly to lack of information and fear of narcotic use in children, in addition to the misconception that neonatal and pediatric patients do not experience pain as severely as adults do [2, 3]. During the last decade, there has been growing interest in denning safe and effective techniques for intraoperative anesthesia and postoperative analgesia for infants and children. This has led to investigating how to safely care for the increasing numbers of premature infants undergoing surgery, and to defining the safety and efficacy of a variety of regional techniques and narcotic use in children of all ages [4–6].
