title: [Examination of acute kidney injury after abdominal aortic aneurysm surgery].
abstract: BACKGROUND
  Either suprarenal or infrarenal aortic clamping markedly reduces renal blood flow. This aortic clamping may cause postoperative acute kidney injury(AKI).
  
  
  METHODS
  Fifty-four patients undergoing open abdominal aortic aneurysm (AAA) surgery were included in a retrospective study. Postoperative AKI defined as an absolute increase in serum creatinine (Cre) of more than or equal to 0.3 mg x dl(-1) or an increase in Cre of more than or equal to 50% within 48 hours after the end of the procedure.
  
  
  RESULTS
  Thirteen patients developed AKI, but none of them required dialysis. The patients with AKI had higher preoperative Cre, longer operation, longer clamp time and more use of diuretics intra- and postoperatively.
  
  
  CONCLUSIONS
  AKI occurred in 24.1% of patients undergoing AAA surgery. Risk factors for AKI were preoperative Cre, operation time, clamp time and use of diuretics.
