This review of the effects of treatment for urinary tract infection in children and of preventive interventions is one of over 60 chapters in the first issue of Clinical Evidence, published by the BMJ Publishing Group.
Treating symptomatic acute urinary tract infection in children with an antibiotic is accepted clinical practice and trials would be considered unethical
We found little evidence on the effects of delaying treatment while awaiting microscopy or culture results, but retrospective observational studies suggest delayed treatment may be associated with increased rates of renal scarring
One systematic review of randomised controlled trials (RCTs) has found that antibiotic treatment for seven days or longer is more effective than shorter courses
We found no convincing evidence of benefit from routine diagnostic imaging of all children with a first urinary tract infection, but subgroups at increased risk of future morbidity may benefit from investigation. Because such children cannot currently be identified clinically, investigating all young children with urinary tract infection may be warranted
Two small RCTs found that prophylactic antibiotics prevented recurrent urinary tract infection in children, particularly during the period of prophylaxis. The long term benefits of prophylaxis have not been adequately evaluated, even for children with vesicoureteric reflux. The optimum duration of treatment is unknown
One systematic review and a subsequent multicentre RCT found no difference between surgery for vesicoureteric reflux and medical management in preventing recurrence or complications from UTI
Definition: Urinary tract infection is defined by the presence of a pure bacterial growth >105 colony forming units/ml. Lower counts of bacteria may be clinically important, especially in boys and in specimens obtained by urinary catheter. Any growth of typical urinary pathogens is considered clinically important if obtained by suprapubic aspiration. In practice, three age ranges are usually considered on the basis of differential …
