Abstract：Objective A ureter obstruction caused by a ureteral stone results in inflammatory changes in the proximal submucosal layer and prevents the spontaneous passage of the ureteral stone. Accordingly, we analyzed the relationship between the spontaneous passage rates of ureteral stones less than 8 mm in size and serum C-reactive protein (CRP) levels and neutrophil percentages. Methods A total of 287 patients who were diagnosed as having ureteral stones less than 8 mm in size and were managed consecutively at Urological Surgery, Department Xinjiang Uigur Autonomous Regional Corps from January 2001 to January 2014 were retrospectively analyzed. Ureteral stone removal was defined as no ureteral stone shown in an imaging test for 4 weeks after diagnosis. The patients were divided into three groups according to the levels of CRP and into two groups according to neutrophil percentage. The associations between these factors and ureteral stone passage rates were then examined.Results The ureteral stone passage rates in the low serum CRP level group, the medium serum CRP level group, and the high serum CRP level group were 94.1%, 70.0%, and 50.0%, respectively. The passage rates of ureteral stones in the group with a normal neutrophil percentage and in the group with a higher neutrophil percentage were 94.5% and 83.1%, respectively.Conclusions When the CRP level and neutrophil percentage in a patient are high, aggressive treatment such as extracorporeal shock wave lithotripsy or ureteroscropy lithotripsy should be considered.
