Wahl et al reported the risk of postoperative acute kidney injury (AKI) based on preoperative glomerular filtration rate (GFR) and level of proteinuria. The authors are from multiple institutions in the United States.
Patient selection: surgical
Parameters:
(1) glomerular filtration rate in mL per min per 1.73 square meters
(2) level of dipstick proteinuria (negative, trace, 1+, 2+, 3+)
