Chi square test used for comparing the categorical variables (Age, gender and side of stone), Student t-test used to compare the mean values of size of stone, CRP, WC and NP. Total number of patients n=192, CRP: C-reactive protein, WC: White blood cell count, NP: Neutrophil percentage, SD: Standard deviation, MET: Medical expulsive therapy
