Multicenter Study Observational StudyTransient versus persistent acute kidney injury and the diagnostic performance of fractional excretion of urea in critically ill patients.
To evaluate the performance of fractional excretion of urea (FeU) for differentiating transient (T) from persistent (P) acute kidney injury (AKI) and to assess performance of FeU in predicting AKI in patients admitted to the ICU. ⋯ FeU does not seem to be helpful in differentiating T- from P-AKI in critically ill patients and it is a poor predictor of AKI.
