Relation between acute kidney injury and pregnancy-related factors

Abstract

Acute kidney injury (AKI) is a serious problem during pregnancy. Once occurred, it brings about devastating maternal and fetal outcomes. Among developed nations, the trend of pregnancy-related AKI (PRAKI) is on a decline due to the advances in obstetrics care and the legality of abortion. On the contrary, this situation remains one of the major health problems in the developing countries. Though some improvements have been observed, PRAKI still causes high maternal morbidity and mortality, leading to fetal losses. This article aims to review current studies with regards to obstetrics related AKI. Most of the studies in this review were carried out in observational, both prospective and retrospective, studies. Results demonstrated a variety of major PRAKI causes such as hypertensive disorders in pregnancy, obstetric hemorrhage, sepsis, thrombotic microangiopathy and acute fatty liver in pregnancy. Aside from awareness of the etiologies of PRAKI, understanding the physiological renal adaptation during pregnancy is crucial for early detection, diagnosis, and proper management to prevent the obstetric complications.
