To the Editor.—
I am interested in the article entitled "Neonatal Bladder Injury Occurring After Umbilical Artery Catheterization by Cutdown."1 I think that if the bladder is empty, one may prevent perforation of the bladder during umbilical artery cutdown. If an 8-F (or smaller) feeding tube is used temporarily to keep the bladder empty, urethral injury can be avoided even in a male newborn.
