Study finds best way to drain urine after penile surgery in boys
NCT ID NCT07421271
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 86 children who had surgery to fix a common birth defect where the urine opening is on the underside of the penis (distal hypospadias). The goal was to find the best way and length of time to drain urine after surgery to prevent a leak (fistula). Researchers compared using a tube in the urethra alone versus adding a tube through the belly, and draining for one week versus two weeks.
