Pregnancy-related AKI is a global health problem and is associated with a higher risk of both maternal and fetal morbidity and mortality. Risk factors for developing AKI during pregnancy include older age, history of preeclampsia, and comorbidities like diabetes. Hyperemesis gravidarum is a common cause of AKI during the first trimester, and conditions such as preeclampsia, acute fatty liver disease of pregnancy, thrombotic thrombocytopenic purpura, hemolytic uremic syndrome, and placental abruption are important causes of AKI later in the pregnancy. Diagnosis of pregnancy-related AKI is challenging due to the lack of standard criteria and overlap of clinical manifestations among different etiologies. Timely diagnosis of pregnancy-related AKI is instrumental. Specific treatment includes steroids and immunosuppressive therapy for glomerulonephritis, prompt delivery for severe preeclampsia and acute fatty liver of pregnancy, plasmapheresis for thrombotic thrombocytopenic purpura, and eculizumab for the atypical hemolytic uremic syndrome. Due to the high complexity, management of pregnancy-related AKI should be performed by a multidisciplinary team consisting of a nephrologist, obstetrician, and neonatologist.
