title: [Primary vesico-ureteral reflux of the newborn].
abstract: Vesico-ureteral reflux (VUR) and urinary tract infections (UTI) are more common in male than female infants. It was demonstrated that Voiding Detrusor Pressure (VDP) is higher in healthy males than healthy females and more in males with VUR versusmales without VUR. Baby boys with severe reflux may present also hypercontractility. During infancy, VDP and hypercontractility generally decrease: this is essential for reflux resolution.
