Is this trial a fit for you?

Likely a good fit

Male children 6–60 months scheduled for elective distal hypospadias repair, whose guardians provide informed consent.

Probably not a fit

Children with non-distal vs proximal hypospadias, prior hypospadias repair, or contraindications to caudal block may not benefit from this approach.

What this trial studies

This is a prospective, multicenter randomized trial enrolling 80 male children aged 6 to 60 months undergoing distal hypospadias repair. Participants are randomized 1:1 to receive caudal block with general anesthesia or general anesthesia alone, with outcomes including fistula formation, wound healing, pain scores, analgesic use, and length of stay tracked for 3–6 months postoperatively. Data on demographics, surgical details, and complications will be collected and analyzed using standard statistical tests. The study aims to clarify whether caudal anesthesia influences postoperative complications in this surgical population. It is conducted across four centers with centralized data analysis.

Why it matters

Potential benefit: If successful, the findings could guide anesthesia choices to minimize postoperative fistula risk after distal hypospadias repair.

How similar studies have gone: Previous observations suggested potential associations between caudal block and postoperative fistula, making this trial a needed, more definitive assessment.
