Özet
Objectives: To evaluate whether the neutrophil-to-lymphocyte ratio (NLR), can differentiate between urinarystone disease and inflammatory conditions in patients admitted to emergency department having acuteabdominal pain accompanied by flank pain.Methods: Data of 191 patients with acute abdominal pain accompanied by flank pain admitted to emergencydepartment in a single institution during 1 year period was retrospectively reviewed. Complete blood countand urine analysis were evaluated, the definitive diagnosis was established radiologically. The NLR wascalculated as the absolute neutrophil count divided by the absolute lymphocyte count. The cut off value for theNLR in relation to stone status was calculated.Results: Of the 191 patients 51.3% (n = 98) were males, 48.7% (n = 93) were females (p > 0.05). White bloodcounts of the patients according to the presence of stone does not show a statistically significant difference (p> 0.05). NLR measurement of patients according to the presence of stone shows a statistically significantdifference (p = 0.009). NLR of patients with urinary stones were significantly lower than patients withouturinary stones. NLR measurements did not differ significantly according to stone location. A cut-off point of? 2.16 for the NLR was determined according to the stone status of the patients. NLR values were higher inpatients with acute abdominal pain/flank pain due to inflammatory pathologies.Conclusion: As the diagnosis and treatment of urolithiasis take long time and require elaborate methods, NLRmay be used as a simple method in the differential diagnosis of pain due to urinary stone disease orinflammatory condition.
