Intermittent catheterization means removing urine from the bladder by placing a tube into the bladder. Pedicatric catheters are typically 4-6 French (diameter) in newborns, 6-8 French in infants, 10-12 French (diameter) in prepubertal girls, and up to 14 French (diameter) in adolescents. They are typically used 4-6 times a day.
