ObjectiveIn 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.MethodsThe 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.ResultsMean age of the 275 patients was 41.0 ± 14.9 and 61.1% of them were male. The patients' mean VAS score was 73.3 ± 16.5.The mean VAS score of the groups of which hematuria and pyuria were positive and which have hydronephrosis finding was statistically higher than those whose were negative. The mean stone size was 5.2 ± 2.1 mm, and those with signs of hydronephrosis on their CT (n = 66) were 5.4 ± 2.3 mm, while those with no signs of hydronephrosis (n = 57) were 4.9 ± 1.7. No statistical difference was found in stone size between patients with hydronephrosis and those without. Not any correlations were determined between the stone size and VAS pain score of the cases.ConclusionsWe detected that the pain level was not correlated with the stone size and big stones were not statistically riskier in the hydronephrosis development. However, we think that the risk of complications such as hydronephrosis is higher in the patients whose pain level are higher and the infection may be accompanied by this group.Copyright © 2019 Elsevier Inc.
