A clean catch urine sample from a child with dysuria and fever shows 50,000 to 100,000 CFU of E. coli. What is the appropriate management?

• A. CBC and CRP testing should be performed.
• B. Sensitivity testing should be done before antibiotics.
• C. Repeat the culture if symptoms persist or worsen.
• D. Treat with antibiotics for urinary tract infection.

Answer: (D)

When a febrile child with dysuria has a clean-catch urine culture showing a substantial amount of E. coli, it confirms a urinary tract infection that should be treated with antibiotics. The presence of bacteria at this level in a symptomatic child is clinically meaningful, and initiating therapy promptly helps reduce the risk of progression to more serious infection and speeds symptom resolution. CBC or CRP testing isn’t required to start treatment in a straightforward UTI in a child; they may be considered if there are signs suggesting systemic illness or complications, but they don’t dictate the need for antibiotics in this scenario. Sensitivity testing before starting antibiotics is not necessary for a simple outpatient UTI—you can begin empiric antibiotics and adjust later if needed based on culture results. Repeating the culture solely if symptoms persist or worsen isn’t the primary step in initial management; you would reassess if there’s no improvement or if there are recurrent episodes.
