Clinical differentiation between acute renal infarction and acute ureteral stone in the emergency department: A single-center retrospective case-control study.

Background: Few studies have compared renal infarction (RI) and ureteral stone (US), so there is insufficient evidence for emergency clinicians (ECs) to quickly suspect RI during the first assessment. Therefore, we compared the initial clinical presentation and laboratory findings of these diseases in the emergency department (ED) to determine a factor that may indicate RI.

Methods: This single-center retrospective case-control study included 42 patients with acute RI and 210 with US who visited the ED from 2014 to 2020.
