Urinary imaging findings in young infants with bacteremic urinary tractinfection.

Abstract

Background: The Urinary Tract Infection (UTIs) is one of the most widely acquired bacterialinfections in infants. UTI sometimes accompanied by bacteremia. Bacteremia is characterising as thedevelopment of a pathogen within the blood culture. Imaging tests, such as a Renal Ultrasound (RUS)and Avoiding Cystourethrogram (VCUG) use to diagnose UTIs. Aim: We aimed to describe RUS and VCUG findings in young infants with bacteremic urinary tractinfection and to determine the association between imaging findings and other variables at a tertiaryhospital in Jeddah, Saudi Arabia. Methods: We retrospectively studied the medical records of 30 infants from both genders who haddiagnosed with bacteremic UTIs at a tertiary hospital in Jeddah, Saudi Arabia. Infants were excludedif they had known urologic abnormalities at the time of presentation, required intensive unite care andinfants with immunocompromised diseases. Data was analyzed by SPSS program. Results: Of the 30 infants, 70% were boys, 50% aged from 0-3 months while the other 50% aged >3months, 14 (46.7%) were Saudis while 16 (53.3%) were non-Saudis, 61.1% were non-febrile, 58.62%had standard creatinine value. All infants 100% underwent RUS, 96.2% of them had RUSabnormalities (18 males and seven females) while only 3.8% (1 male) had typical RUS result. 37.9% ofinfants underwent VCUG, 18.2% (2 miles) of them had normal VCUG, while the majority 81.8% (7males and two females) had abnormal findings. 17.9% presented with VUR. There was no significantassociation between RUS results with sex, age group, creatinine value and urine cultures. On anotherhand, there was a significant association between RUS abnormal result and blood culture. Also, nosignificant association found between VCUG results with sex, age group, creatinine, blood and urinecultures. Conclusion: In conclusion, the prevalence of RUS and VCUG abnormality in our cohort found to behigher than other studies. There was a significant association between RUS finding and blood cultureresults; on another hand, there was no significant association between RUS and VCUG findings withother variables that could suggest bacteremic risk in UTI infants.
