Abstract: Acute kidney injury is a common complication of critically ill patients,  and itsrecovery is closely related to the shortterm and longterm prognosis. Taking effective monitoring measures to judge its reversibility and the influencing factors is the key to implement effective interventions and improve the prognosis. Renal recoverability rests on many factors such as types and extent of injury,  local renal factors and systemic conditions. In order to facilitate clinical practice,  the article explores  its risk factors,  clinical information,  pathology,  molecular markers,  imaging methods,  renal blood flow status and other aspects.

Key words: acute kidney injury, recoverability
