Multicenter StudyThe association of albumin/creatinine ratio with postoperative AKI in children undergoing cardiac surgery.
This study determined if preoperative and postoperative urine albumin/creatinine ratios (ACRs) predict postoperative AKI in children undergoing cardiac surgery (CS). ⋯ Postoperative ACR is a readily available early diagnostic test for AKI after pediatric CS that performs similarly to other AKI biomarkers; however, its use is enhanced in children aged ≥2 years and in combination with serum cystatin C.

Association of postoperative proteinuria with AKI after cardiac surgery among patients at high risk.
Preoperative proteinuria is associated with a higher incidence of postoperative AKI. Whether the same is true for postoperative proteinuria is uncertain. This study tested the hypothesis that increased proteinuria after cardiac surgery is associated with an increased risk for AKI. ⋯ Higher levels of proteinuria after cardiac surgery identify patients at increased risk for AKI during their hospital stay.
