pyuria

Fever without a source, think UTI first
Fever without a source, think UTI firstIn children aged older than 2 months, the pediatrician is often faced with the scenario of fever with no apparent source. Because symptoms in young patients are nonspecific and reliable urine samples require invasive testing, there can be a delay in both diagnosis and treatment of urinary tract infections (UTIs). This delay may be associated with increased risk of renal scarring and a longer duration symptomology for the young child.
Concentration matters in newer urinalysis techniquesIn a retrospective study of 27,000 infants aged younger than 3 months evaluated for urinary tract infection (UTI) with paired urinalysis and urine culture, investigators set out to determine the optimal urine white blood cell (WBC) threshold for UTI when using an automated urinalysis system stratified by urine concentration.
Some uropathogens more associated with pyuria than othersA new study demonstrated that in children with an apparent urinary tract infection, the proportion with pyuria varied significantly depending on the uropathogen associated with the infection.
