Summary

This trial investigates whether a caudal nerve block, a common pain-relief method for children, increases the chance of a fistula (an abnormal opening) after surgery to correct hypospadias, a birth defect where the urine opening is on the underside of the penis. About 80 boys aged 6 months to 5 years will be randomly assigned to receive either general anesthesia alone or general anesthesia plus a caudal block. Researchers will track fistula rates, pain levels, and other complications over 3-6 months to guide safer surgical practices.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: bupivacaine hydrochloride (caudal block)
What this could lead to: If results show caudal block increases fistula risk, surgeons may avoid it, reducing complications for thousands of boys.
What could go wrong: This is a small, early-stage trial (80 patients) that may not apply to all hospitals or techniques. The link between caudal block and fistula is still uncertain.
