Laboratory parameters can be used to differentiate renal infarction and urolithiasis in patients who are admitted to the emergency department with flank pain

Abstract

Abstract Aim We aimed to determine the predictive value of laboratory parameters for the distinction between urolithiasis (UL) and renal infarction (RI) in patients presenting to the emergency department with flank pain complaint. Methods In our retrospective study, the files of 73 patients who presented to the emergency department (ED) with flank pain and whose costovertebral angle tenderness was positive were reviewed. Routine blood tests and the results of contrast-enhanced abdominal computed tomography were obtained. The patients were divided into two groups as RI and UL according to the results of computed tomography. Accordingly, 8 patients were found to have RI, and 65 had UL. Results LDH and PLR values were significantly higher in the RI group compared to the UL group (p
