ABSTRACT
Objective To explore diagnostic value of the serum and urine procalcitonin (PCT) detecting in the urinary system infection.Methods The serum and urine PCT levels in 45 urinary system infection patients with clear pathological diagnosis (exclude other system infections) who were outpatiented or hospitalized in the People's Hospital of Zhongshan between March and November 2016 (including 21 cases of upper urinary tract infection and 24 cases of lower urinary tract infection) and 35 healthy adults who went through physical examinations at the hospital during the same period,were measured using electrochemiluminescence immunoassay (ECLIA) on Cobase 601 Immunoassay Analyzer and analyzed to compare the differences of PCT levels in the three groups.Results The urine PCT level in upper urinary tract infection group was 0.243± 0.123 ng/ml.It was significantly lower than lower urinary tract infection group (0.486±0.232 ng/ml,t=4.11,P=0.000) and control group (0.454± 0.253 ng/ml,t=3.96,P=0.000).The serum PCT level in upper urinary tract infection group was 0.062±0.014 ng/ml.It was obviously higher than that in lower urinary tract infection group (0.043±0.020 ng/ml,t=3.56,P=0.01) and control group (0.032±0.013 ng/ml,t=7.38,P=0.000).In all groups,the urine PCT levels were significantly higher than their serum PCT levels (t =9.48,9.12,6.79,P< 0.01),and significant differences were observed in them.The sensitivity,specificity,positive predictive value and negative predictive value of serum PCT for diagnosing upper urinary tract infections were 81.5%,84.2%,80.6% and 85.6% respectively,and the urine PCT were 86.4%,80.7%,88.4 % and 83.1 % respectively.Conclusion Detection of serum and urine PCT has important accessory diagnostic value for identifying upper and lower urinary tract infections.
