Pleural effusion was supposed to be a risk factor for acute kidney injury (AKI). Incidence of AKI in NMPE patients and whether there is correlation between the size of effusions and AKI is unknown.<h4>Objective</h4>To assess the incidence of AKI in NMPE inpatients and its association with effusion size.<h4>Study design and method</h4>We conducted a retrospective cohort study of inpatients admitted to the Chinese PLA General Hospital with pleural effusion from 2018-2021. All patients with pleural effusions confirmed by chest radiography (CT or X-ray) were included, excluding patients with diagnosis of malignancy, chronic dialysis, end-stage renal disease (ESRD), community-acquired ABMC nephrologyAcute kidney injury in hospitalized patients with nonmalignant pleural effusions: a retrospective cohort study.PMC10983765No.32141005, No.82274327No.2022YFC3602005, No.2021YFC3002203Li CFeng ZCao XWang DLi PZhang LChen XLiu FNiu YChen DCai GfalseAcute kidney injury in hospitalized patients with nonmalignant pleural effusions: a retrospective cohort study.<h4>Background</h4>Nonmalignant pleural effusion (NMPE) is common and remains a definite health care problem.
