Some studies have shown that The Urinary Uric Acid \/ Cr (UUA\/Cr) ratio may be used as an additional marker for perinatal asphyxia.This study intend to investigate the relationship of this ratio with outcomes of preterm infants admitted to NICU.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This case\u2013control study was carried on 102 preterm newborn infants with gestational age of 30\u00a0weeks to 33\u00a0weeks and 6\u00a0days admitted in the neonatal intensive care unit.The case group, consisted of 51 premature neonates with a history of intubation, cardiopulmonary resuscitation, mechanical ventilation and Nasal continuous positive airway pressure (NCPAP) at birth, were compared with 51 matched neonates. The UUA\/Cr ratio was measured in the first 24\u00a0h after birth.

The UUA\/Cr ratio were significantly higher in females, cesarean section delivery, Apgar score\u2009\u2265\u20098, neonates without any complication and neonates with less than 10\u00a0days of hospitalization.
