Urinary Tract Infections, Pediatric
Basics
Description
Description
- Bacteria colonize via retrograde contamination of rectal or perineal flora:
- Infants – often hematogenous spread
- Older children – vesicoureteral reflux (VUR) major risk
- UTI is defined by culture of a single organism of >50,000/mL on a catheterized or suprapubic specimen. Other collection techniques are not routinely used in young children for definitive diagnosis
- By 6 yr of age, 2% of boys and 8% of girls have had a UTI
- In infants 0–3 mo old, UTI is associated with a 30% incidence of sepsis
- Predisposing factors:
- Poor perineal hygiene
- Short urethra of female
- Female > male
- Infrequent voiding
- Constipation
- Sexual activity
- Male circumcision probably reduces risk
- Vesicoureteral reflux (VUR)/obstruction to flow
- Bladder dysfunction
- Hypercalciuria
