AB  - Urine  output  has  been  scant  or  absent  for  24  hours.  One  hundred  percent  of  healthy  premature,  full-term,  and  post-term  infants  void  by  24  hours  of  age.  Oliguria  is  defined  as  urine  output  <1.0  mL/kg/h  for  24  hours.  Anuria  is  defined  as  absence  of  urine  output  usually  by  48  hours  of  age.  Oliguria  is  one  of  the  clinical  hallmarks  of  renal  failure.  Decreased  urine  output  can  be  from  mild  dehydration  or  acute  renal  failure  (ARF)  or  acute  kidney  injury  (AKI).  ARF/AKI  is  an  acute  renal  dysfunction  and  occurs  when  there  is  a  decrease  in  glomerular  filtration  rate,  an  increase  in  creatinine  and  nitrogenous  waste  products  with  the  loss  of  ability  to  regulate  fluid  and  electrolytes.  Incidence  of  neonatal  ARF/AKI  is  around  6–24%.  There  is  a  high  percentage  of  ARF/AKI  in  very  low  birthweight  infants,  infants  postcongenital  heart  surgery,  infants  on  extracorporeal  membrane  oxygenation/extracorporeal  life  support  (ECMO/ECLS)  (especially  with  a  congenital  diaphragmatic  hernia),  and  infants  with  perinatal  depression.
