The aim of this prospective randomized study is to assess the analgesic efficacy and duration of Pudendal block compared with Caudal block for pediatric patients undergoing hypospadias surgery concerning intraoperative analgesic and also postoperative total analgesic consumption within 24 hours.
In this prospective study, patients will be randomized into 2 groups, either receiving Caudal Block(CB) or nerve stimulator-guided Pudendal Nerve Block(PNB). Analgesic consumption will be assessed during the first 24 hours postoperatively. The "CHEOPS pain scale" will use to assess postoperative pain.

nerve stimulator-guided Pudendal block
caudal block
postoperative pain intensity measure
pain scores are recorded (postoperative within 24 hours) the investigators use CHEOPS pain scale for evaluation pain intensity. When pain score is 7 or higher than 7, pain treatment is evaluated as inadequate.
Time frame: 24 hours
time to to first use of analgesic
Time frame: 24 hours
parental satisfaction
Parent satisfaction was scored as: 1. definitely unsatisfied; 2. satisfied; 3. definitely satisfied.
Time frame: 24 hours
the incidence of side effects
Time frame: 24 hours
intraoperative analgesic requirement
intraoperative remifentanil infusion requirement ( If heart rate and/or blood pressure increase 20% than first measure, we will start remifentanil infusion)
Time frame: intraoperative
postoperative total analgesic requirements
Time frame: 24 hours
