INTRODUCTION: The aim of the study is to estimate whether ureteral stones are impacted by using acute phase reactants
METHODS: Between January 2017 and December 2017, the data of 110 patients
having single ureteral stone receiving medical expulsive therapy (MET) with tamsulosin 0.4 mg/day, diclofenac 75 mg upon analgesic requirement and at least 3 liters fluid per day during one month were evaluated prospectively. Patients underwent ureteroscopy and were divided into two groups according to impaction. The two groups were compared with statistical analysis. The preoperative WBC, RDW, CRP, SED, MPV, NLR values in non-impacted stone group 1(N=59) and impacted group 2 (N=51) were compared.
RESULTS: There was no statistically significant difference in terms of age, stone diameters, body mass index (BMI), grade of hydronephrosis and stone localizations between both groups. WBC, RDW, MPV values differences were statistically significant between groups 1 and 2 (0,035, 0,035 and 0,005 respectively). MPV with a cut off value of 9.55 was defined in group 2 with 66% sensitivity and 62% specificity. There was no statistically significant difference between two groups regarding CRP, Sedimentation and NLR values. (p=0,44, 0,76, 0,54 respectively)
DISCUSSION AND CONCLUSION: Evaluation of serum MPV may predict ureteral stone impaction with the cut-off value of 9.55.
