Background: Plasma C-Reactive Protein (CRP) is an acute-phase protein whose serum level increases in response to inflammation, as happens in impacted ureteric calculus. Few studies have investigated the efficacy of silodosin, a selective alpha 1-A adrenoceptor antagonist, in medical expulsive therapy (MET) for distal ureteral calculi. The studies showed the efficacy of silodosin 8 mg/day as a potential treatment for distal ureteric calculus expulsion. In this study wedetermined the correlation of CRP Levels at the starting of MET and the success of METwith SILODOSIN after 3 weeks. Materials and Methods: 70 patients with distal ureteric calculus between 5-9 mm size were included in this study. They were divided into 2 groups based on the initial CRP level at the time of first presentation to the hospital.CRP level of 6mg/L was taken as cut-off. Group 1 with 35 patients having CRP value morethan 6and Group 2 with 35 patients having CRP value of less than 6.
