Acute kidney injury (AKI) has been identified as an independent risk factor for in-hospital mortality. The present study aims to investigate the incidence of AKI and renal recovery of inpatients diagnosed with COVID-19.

Beginning in December 2019, a novel coronavirus, designated as severe acute respiratory distress coronavirus 2 (SARS-CoV-2), has caused an international outbreak of respiratory illness termed coronavirus disease 2019 (COVID-19). Although the clinical manifestations of COVID-19 are dominated by respiratory symptoms, some patients show severe kidney abnormalities. Acute kidney injury (AKI) has been identified as an independent risk factor for in-hospital mortality. The present study aims to investigate the incidence of AKI and renal recovery of inpatients diagnosed with COVID-19.
