The management of urinary tract infection in children must rake into a
ccount several factors, namely the type of bacteria, the localization
of the infection, the presence of an uropathy and the age of the patie
nt. In acute pyelonephritis, the risk of renal scarring justifies a fi
rst line treatment with two antibiotics to be administrated intravenou
sly in newborns and infants. Treatment must be maintained for at least
10 days: double antibiotherapy for 4-5 days, followed by oral monothe
rapy according to the antibiogram. Cystitis requires an oral monothera
py for 3-7 days. In any case it is important to search for a cause to
the infection.
