Abstract
Introduction: Computed tomography (CT) is a key method for various disorders. Image can be more quality with intravenous contrast media, however in some cases may be accompanied by a risk of kidney impairment.
Objectives: This study aimed to investigate the association between acute kidney injury incidence and intravenous contrast media for CT in emergency patients.
Methods and Materials: Search strategies were performed using standard keywords across international databases such as Web of Science, Scopus, Cochrane, PubMed, and Embase. Dimension, OpenGrey, DOAJ, CINAHL, and Google Scholar search engines were searched for a complete search. Additionally, manual searching was conducted using the references of related articles. Studies that reported the correlation between acute kidney injury incidence and intravenous contrast media were included in this systematic review.
Results: First, 1185 studies were identified. After duplication, 533 studies remained and 417 were excluded. Out of 116 evaluated studies for retrieval, 49 were eliminated and 67 were assessed for eligibility. Ultimately, 28 studies with 48878 patients were included in the final review. Most of the studies were retrospective cohorts and have found no significant correlation between the incidence of acute kidney injury and intravenous contrast media administration (ICMA) for CT.
Conclusion: Intravenous contrast media with a conventional dose for CT does not cause acute kidney injury unless in the presence of a particular condition.
Registration: This study was compiled following the PRISMA checklist and its protocol was registered on the PROSPERO (CRD42023448461) and Research Registry (UIN: reviewregistry1690) websites.
