简要总结
An investigator-initiated, open-label, multi-center, randomized, non-inferiority trial of children aged 3 months to 13 years with acute uncomplicated febrile urinary tract infection. The primary objective is to determine whether individualized antibiotic therapy based on an algorithm (experimental arm) versus standard antibiotic therapy of 10 days (control arm) can reduce the number of days with antibiotic therapy within 28 days after treatment initiation without increasing the risk of recurrent urinary tract infection regardless of the pathogen or death of any cause within 28 days after end of treatment. Children will be randomized 1:1. The medical treatments received are identical in both groups.

入选标准
- •Clinical suspicion of febrile (≥38 °C) urinary tract infection.
- •Positive urine culture of uropathogenic bacteria obtained by either suprapubic bladder aspiration, sterile intermittent catheterization, or midstream urine.
- •Suprapubic bladder aspiration: any growth of bacteria.
- •Sterile intermittent catheterization: monoculture with ≥10^3 cfu/ml.
- •Midstream urine x 2: Monoculture with the bacteria in both tests with ≥10^4 cfu/ml.
- •Midstream urine x 2: Monoculture with the bacteria in both tests with ≥10^5 cfu/ml in one test and 10^3 cfu/ml in another test.
- •Midstream urine x 1 (≥10 years of age): Monoculture with ≥10^5 cfu/ml.
- •3 months to 13 years of age (corrected age in case of premature birth).
- •Parents fluent in Danish or English.
- •Informed consent both parents.
- •All children who do not receive any empirical antibiotic therapy but have a positive urine culture (approximately 48 hours after urine sample collection) can be included if fever (≥ 38.0 °C) is present and the child is initiated with relevant antibiotic therapy. ¨
- •Children can be included regardless of whether intravenous or oral antibiotics were given as empirical therapy.
排除标准

- •Antibiotic treatment in the last two weeks before the primary visit.
- •Three or more episodes with febrile (≥38 °C) urinary tract infection within one year of the primary visit (including the current episode).
- •Previous complicated episode of febrile (≥38 °C) urinary tract infection (e.g., renal abscess or urosepticemia)
- •Non-compliance ≥3 doses of antibiotics during empirical therapy.
- •Elevated creatinine.
- •Prophylactic antibiotic treatment.
- •Known urogenital abnormalities (i.e., obstructing uropathies; vesicoureteral reflux; multicystic dysplasia; renal dysplasia; renal hypoplasia; renal agenesis; duplex kidney; polycystic kidney disease; neurogenic bladder dysfunction; hypospadias).
- •Positive blood culture (if contamination is not suspected).
- •Immune deficiency.
- •Systemic immunosuppressive therapy.
