Incidence of Congenital Urinary System Anomaly in Newborns with Urinary Tract Infection

Özet

Introduction: Childhood urinary tract infection (UTI) is one of the most important causes of renal failure in adult age. The presence of congenital urinary malformation should be investigated. In this study, by evaluating new-borns with UTI who were hospitalized in our clinic, we aimed to find clues that will help clinicians for choosing the right imaging methods. Methods: This research includes 137 neonates who were hospitalized with the diagnosis of UTI or diagnosed as UTI after hospitalization in Zeynep Kamil Gynecologic and Pediatric Training and Research Hospital NICU-2 between January 2009-October 2012. All patients’ demographic characteristics and urinary tract imaging were evaluated. Results: Of the 137 neonates included in this study, 78.8% of them was male, and 21.2% of them was female. In 19% of the patients, abnormalities were detected with urinary tract ultrasonography. The most frequent abnormality was hydronephrosis and ectasia 13.9%. In 39 of the patients, three imaging technique was performed. Of the patients with abnormal urinary system ultrasound, 47.1% of them had pathologic voiding cystourethrography, and 58.8% of them had pathologic DMSA scintigraphy. Abnormal VCUG and DMSA rates were 9.1% in patients with normal urinary system ultrasonography. Discussion and Conclusion: Urinary tract USG should be performed to each patient who was diagnosed as urinary tract infection in the newborn period because of this may be a signal of the urinary system abnormality. Choice of the advanced imaging modalities should be decided according to the patient's characteristics.
