The relationship between the severity of pain and stone size, hydronephrosis and laboratory parameters in renal colic attack.

Objective: In this study, we investigated the relationship between the severity of pain level and hydronephrosis, hematuria and pyuria presence in the acute renal colic attack and whether there was a correlation between the stone size and inflammatory markers.

Methods: The patients' pain scores determined by Visual Analog Scale (VAS), CRP, WBC and NLR levels from the laboratory results, hematuria and pyuria presence in the urine analysis and hydronephrosis presence in the imaging methods were recorded. Moreover, stone size was measured for the patients for whom computed tomography (CT) method was applied.
