    Study Notes

    Urinary Tract Infections (UTIs) in Childhood

    • UTIs are common bacterial infections in children, affecting 8% of girls and 1% of boys in the first 10 years of life.
    • Females are predominantly affected, except in the first six months.
    • Recurrence rates are 50% in girls and 15% in boys.
    • Fever is present in 50% of cases.

    Diagnosis

    • Urine microbiology is the basis of diagnosis.
    • Midstream urine sample (MSSU) or clean-catch urine (CCU) are preferred, with >105 colony-forming units (CFU)/mL indicating infection.
    • If clinical urgency exists, suprapubic aspiration or urethral catheterization may be used, aiming for >10³ CFU/mL.
    • Urine collected in adhesive bags or pads is prone to contamination.

    Pyuria

    • Pyuria (presence of white blood cells in urine) is a useful rapid investigation.

    • 10 white blood cells/mm³ in boys, and > 50/mm³ in girls, is a helpful indicator of UTI.

    • Pyuria may be absent in 25% of recurrent UTIs.
    • Pyuria isn't always indicative of significant bacteruria (bacteria in urine).

    Leucocyte Esterase and Nitrite

    • Combination dipstick urinalysis (measuring leucocyte esterase and nitrite) is faster and less expensive than microscopy.
    • Absence in children older than 2 years can make Urine culture potentially avoidable.
    • This is because urinary tract symptoms become a more reliable indication of infection in older individuals.
    • Sensitivity is lower in infants.

    Infectious Agents

    • Escherichia coli is the leading cause of community-acquired UTIs in children (up to 75%).
    • Enterococci, Klebsiella, Proteus, Serratia, and others account for the remainder.
    • UTIs usually ascend from the urethra, with urinary stasis (urine retention) contributing to risk.

    Conditions Contributing to UTIs

    • Anatomical obstructions
    • Vesicoureteric reflux (VUR)
    • Incomplete or inefficient voiding habits
    • Low fluid intake
    • Constipation

    Upper and Lower Tract UTIs

    • Upper tract: Fever, lethargy, general malaise, vomiting, loin pain.
    • Lower tract: dysuria, urgency, frequency, wetting, frank haematuria, non-specific abdominal pain.

    Treatment

    • Antibiotics should initially be selected based on a educated guess, followed by culture and sensitivity.
    • Oral administration (Trimethoprim, Co-amoxiclav, Nitrofurantoin, Cephradine)
    • IV therapy may be required in infants and young children , more seriously ill or those who aren't responding.
    • Third-generation cephalosporins (cefotaxime, ceftazidime, ceftriaxone) or aminoglycoside and amoxicillin combinations can be used in hospitalized patients
    • Antibiotics are given for 7-10 days for both upper and lower tracts.
    • Prophylaxis may be needed until the urinary tract is fully investigated.

    Vesicoureteric Reflux (VUR)

    • Retrograde flow of urine from bladder to ureter.
    • Common in UTI patients (30%).
    • Occurs in ~1% of healthy neonates.
    • Related to underlying conditions such as urethral obstruction or neuropathic bladder dysfunction.

    Long-Term Implications

    • Children with high-grade VUR with scarring, and those with high-grade VUR with malformations might have long-term complications such as acute pyelonephritis.
    • Data suggest risk of hypertension or chronic renal insufficiency with bilateral renal scarring but is limited likely occurs only in those with renal dysplasia.
