This is a prospective randomized multi-center non-inferiority trial conducted through the Pediatric Regional Anesthesia Network study sites to determine if caudal block increases the incidence of urethrocutaneous fistula following distal or mid shaft hypospadias repair compared with penile nerve block.
Small retrospective series are in conflict about whether there is an association between caudal block and urethrocutaneous fistulas after hypospadias repair. The most common alternative to caudal blockade is a penile nerve block. The investigators will test the following hypothesis: There is no difference in the incidence of urethrocutaneous fistula formation following single stage hypospadias repair with caudal anesthesia compared with penile nerve block. The investigators will use a prospective randomized controlled design where subjects will receive either a caudal block or a penile nerve block to provide postoperative analgesia. Meatal anatomy will be graded by the urologist in the anesthetized child according to the HOPE (Hypospadias Objective Penile Evaluation) score, a validated scoring system. Both the total score and the individual component scores will be recorded. The operating urologist will determine the presence or absence of a fistula at the postoperative visit about 12 weeks after surgery, with subsequent follow up at 6 months and again at 12 months.

Incidence of urethrocutaneous fistula
Presence of a urethrocutaneous fistula at postoperative visit up to 1 year after surgery.
Time frame: 1 year
Degree of efficacy of caudal block
Blocks will be graded for efficacy using the following scale: Successful, Probably Successful, Probably Failed, or Failed.
Time frame: 1 hour after arrival in Post Anesthesia Care Unit (PACU) post surgery

Time frame: 1 hour after arrival in PACU post surgery
Need for supplemental analgesics
Administration of opioid in the first postoperative hour will be determined
Time frame: 1 hour after arrival in PACU post surgery
