Important Factors in Emergence of Cortical Defect after UTI among Children

urinary tract infection (UTI) is one of the most important diseases in children, as respect to its complications, every patient with UTI should be followed. Diagnosis and management of complications can decrease its morbidity and mortality. This study was carried out in Mofid children hospital to determine the important factors in emergence of cortical defect after UTI. all patients who were diagnosed as cases of pyelonephritis were enrolled in this cross-sectional study. Pyelonephritis was diagnosed on the basis of clinical and para-clinical criteria. In addition, cortical defect was diagnosed by DMSA scan. Incidence of kidney defect in each kidney, vesicouretral reflux, age, white blood cell count, ESR, positive history of UTI, and leukocyturia were ascertained and analyzed. 163 patients with UTI had the including criteria of this study. We found cortical defect in 41 kidneys (12/6%). Presence of vesicouretral reflux, increased ESR, positive history of UTI, increase in white blood cell count and age older than 2, were the risk factors for cortical defect after UTI. We found that the emergence of cortical defect after UTI had correlation with above mentioned variables. However, DMSA scan is recommended to follow up pyelonephritis, especially in cases having these risk factors
