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.
