Low antithrombin levels accompanied by high urine protein/creatinine ratios are predictive of acute kidney injury among CS patients with preeclampsia

Previous acute kidney injury (AKI) is reportedly a risk factor for future preeclampsia (PE), and PE in current pregnancies may trigger the onset of AKI. In this study, we identified risk factors for AKI among Cesarean section (CS) patients with PE.We performed a retrospective study at a single center. Among 4602 deliveries between January 2017 and July 2018, 944 women underwent CS. Of these, 90 women had hypertensive disorders during their pregnancies, with 53 diagnoses of PE and 37 diagnoses of gestational hypertension. Medical records of the 90 women were reviewed retrospectively.The rate of AKI was significantly higher in the PE group than in the GH group (17 versus 3%,These data demonstrate that lower preoperative serum albumin levels, ATIII activities, and heavy proteinuria among CS patients with PE are risk factors for AKI.
