Newborns who pass stool but not urine do not need to worry about it for the time being if it happens within 1-2 days after birth. In general, 93% of newborns pass urine within 1 day after birth; 99% of newborns pass urine within 48 hours after birth, which means that a few percent of newborns may not pass urine within 1-2 days after birth. If the baby has not urinated for more than 48 hours, it is recommended to have an ultrasound of the urinary system to rule out the presence of urinary abnormalities. In addition, it is important to note that feeding can be intensified, such as giving formula, increasing breastfeeding, and increasing hydration to promote urination, and also by massaging the bladder to promote urination.
