Which pain block is best for little boys after penile surgery?
NCT ID NCT07306806
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two ways to numb pain after hypospadias repair in 30 boys aged 1-8 years. One group got a shot near the tailbone (caudal block), the other near the penis (dorsal penile block). The caudal block worked better for the first few hours and reduced the need for extra pain medicine, but it delayed walking. Both methods were safe and effective.
