Summary

Hypospadias repair is a urological surgical operation that is very painful in the postoperative period and requires long-term analgesia. A dorsal penial nerve block (DPNB) and pudendal nerve block (PNB), which are regional anesthesia techniques for this operation, are used to provide postoperative analgesia.

Detailed description

The regional anesthesia techniques used for postoperative analgesia in hypospadias repair include the peripheral nerve blocks of pudendal nerve block (PNB) and dorsal penile nerve block (DPNB). Ultrasound (US) has recently become increasingly popular in regional anesthesia practice and is used to aid these two peripheral nerve block applications in various pediatric urological procedures. US-guided DPNB has been shown to provide effective and long-term analgesia when compared to caudal epidural block in a recent study on hypospadias surgery in the pediatric population.

Conditions

• Regional Anesthesia
• Hypospadias

Interventions

Type	Name	Description
PROCEDURE	Pudendal nerve block group	A 22 Gauge 50 mm insulated needle was then introduced in the anterior-posterior direction at the middle of the ultrasound probe's superior edge with an out-of-plane approach and using an inclination of 15° in the sagittal plane. The needle tip's position was identified by direct visualization using the movement of adjacent anatomical structures.
PROCEDURE	Dorsal penile nerve block group	Half of the total 0.2 ml/kg dose of 0.25% bupivacaine was administered while observing its distribution with US. The same procedure was then repeated on the other side of the penis.
