AB  - Oliguria  and  anuria  are  defined  as  urine  output  less  than  0.5  mL/kg/h  and  less  than  50  mL/d,  respectively.  Frequently  observed  in  the  postoperative  period,  oliguria  and  anuria  may  be  the  initial  presenting  sign  of  acute  kidney  injury  (AKI),  a  condition  associated  with  significant  perioperative  morbidity.  Acute  renal  failure  (ARF)  in  the  perioperative  setting  is  a  serious  surgical  complication  as  over  50%  of  acute  hemodialysis  patients  have  perioperative  ARF.  The  mortality  rate  for  perioperative  ARF  remains  in  the  range  of  20%–80%  depending  upon  patient  comorbidities.  More  than  90%  of  perioperative  ARFs  result  from  relative  hypovolemia  with  inadequate  renal  perfusion.  The  Kidney  Disease  Improving  Global  Outcomes  (KDIGO)  criteria  for  AKI  are  defined  in  Table  90-1.
