Abstract
Urinary tract infection (UTI) is defined as the growth of microorganisms in a sterile urine culture in a patient with compatible clinical symptoms. The presence of bacteria without any symptoms is known as asymptomatic bacteriuria, and does not require any treatment. In neonates and infants, fever is the guiding sign to suspecting a UTI. Classic urinary tract symptoms become more important in older children. Urine cultures collected before starting antibiotics is always required for diagnosis. Clean-catch (midstream) specimens should be collected for urine culture. In the case of non-toilet-trained children, specimens must be obtained by urinary catheterisation, or suprapubic puncture in neonates and infants. Specimens collected by urine bag should not be used for urine culture. There are no significant differences in the clinical evolution and prognosis between oral versus short intravenous followed by oral antibiotic. Empirical antibiotic therapy should be guided by local susceptibility patterns. Second-generation cephalosporin (children under 6 years) and fosfomycin trometamol (over 6 years), are the empiric therapy recommended in this consensus. In the case of pyelonephritis, recommended antibiotic treatment are third-generation cephalosporins (outpatient care) or, if admission is required, aminoglycosides. Ampicillin should be added in infants less than 3 months old. Antibiotic de-escalation should be always practiced once the result of the urine culture is known.
