This article is from BMC Urology, volume 14.AbstractBackground: Urinary infections are a common type of pediatric disease, and their treatment and prognosis are closely correlated with infection location. Common clinical manifestations and laboratory tests are insufficient to differentiate between acute pyelonephritis and lower urinary tract infection. This study was conducted to explore a diagnostic method for upper and lower urinary tract infection differentiation. Methods: The diagnostic values of procalcitonin PCT and C-reactive protein CRP were analyzed using the receiver operating characteristic curve method for upper and lower urinary tract infection differentiation. PCT was determined using chemiluminescent immunoassay. Results: The PCT and CRP values in children with acute pyelonephritis were significantly higher than those in children with lower urinary tract infection 3.90 ± 3.51 ng-ml and 68.17 ± 39.42 mg-l vs. 0.48 ± 0.39 ng-ml and 21.39 ± 14.92 mg-l. The PCT values were correlated with the degree of renal involvement, whereas the CRP values failed to show such a significant correlation. PCT had a sensitivity of 90.47% and a specificity of 88% in predicting nephropathia, whereas CRP had sensitivity of 85.71% and a specificity of 48%. Conclusions: Both PCT and CRP can be used for upper and lower urinary tract infection differentiation, but PCT has higher sensitivity and specificity in predicting pyelonephritis than CRP. PCT showed better results than CRP. PCT values were also correlated with the degree of renal involvement.
