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.
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.
