Acute kidney injury (AKI) is a major health concern because it is associated with increased morbidity and mortality. While therapies for AKI have improved in recent years, the prevalence of this condition is still high and continues to increase. Considering these clinical issues, the appropriate detection and management of risk factors related to AKI are important issues for clinicians managing AKI patients. This book discusses the forms of detection, predictors and long-term outcomes for acute kidney injuries.
