ABSTRACT
Objective To investigate the value of procalcitonin (PCT) for urosepsis secondary to ureteral calculus.Methods Samples of 68 ureteral calculi patients who were suspected of urosepsis were obtained for PCT level,C-reactive protein (CRP) level,blood routine examination,urinary sediment,blood culture and urine culture.Sixty-eighy patients were divided into urosepsis group and non-urosepsis group based on the urosepsis diagnostic standard.The age sex,stone location,stone size,blood WBC count,CRP level,PCT level and urine WBC count were compared between the 2 groups.PCT levels before and after treatment were also compared.Results The age,stone size in urosepsis group were significantly higher than those in non-urosepsis group.The PCT levels of patients in urosepsis group and non-urosepsis group were 19.09±25.15 μg/L and 2.09± 1.85 μg/L respectively before treatment,and there was a significant difference between the 2 groups (P＜0.05).The blood WBC counts (× 109/L) of patients in urosepsis group and non-urosepsis group were 11.00± 3.47 and 10.27±2.32 respectively before treatment (P＞0.05).The CRP levels of patients in urosepsis group and non-urosepsis group were 17.41±15.24 mg/L and 15.02±4.94 mg/L respectively before treatment (P＞0.05).The median urine WBC counts (per HPF) of patients in urosepsis group and non-urosepsis group were 54 and 47 respectively before treatment (P＞0.05).The PCT levels of patients in urosepsis group before and after treatment were 19.09 ± 25.15 μg/L and 1.06 ± 0.56 μg/L,and there was a significant difference (P＜0.05).Conclusion PCT has a definite value for early diagnosis of urosepsis,condition assessment and treatment guideline.
