Insights
Urinary tract infections (UTIs) in children often have vague symptoms. Early diagnosis and treatment are key to preventing kidney damage and scarring.
Area of Science:
- Pediatric Nephrology
- Infectious Diseases
Context:
- Urinary tract infections (UTIs) present diverse clinical forms in children, influenced by infection severity, location, and age.
- Non-specific symptoms are common in pediatric UTIs, complicating early recognition.
Purpose:
- To outline diagnostic approaches for pediatric UTIs, emphasizing key investigations and their roles.
- To discuss factors influencing UTI development, common pathogens, and the significance of early intervention.
Summary:
- Gram-negative enteric bacteria are the primary UTI pathogens. Urine culture identifies the organism and its antibiotic sensitivity, while urinalysis and leukocyte count assess inflammation intensity.
- Ultrasonography (USG) detects urinary stasis. DMSA scans identify acute pyelonephritis and renal scars. Normal USG/DMSA may obviate the need for voiding cystourethrography (VCU).
- Vesicoureteric reflux (VUR) does not always lead to renal damage. Prompt UTI treatment (within 24 hours) reduces acute renal involvement but not scar formation.
Impact:
- Highlights the importance of timely diagnosis and treatment in preventing long-term renal sequelae in children with UTIs.
- Underscores the role of diagnostic imaging like USG and DMSA scans in managing pediatric UTIs and guiding further investigations.
- Emphasizes preventive measures including hygiene, voiding, hydration, and constipation management for UTI prophylaxis in children.
Abstract:
Urinary tract infections (UTI) could present with different clinical forms dependent on intensity and localization of infection and child's age. The symptoms could be non specific in children. Condition that provoke to urinary stasis, especially voiding dysfunction is the favourable factor for UTI appearance. Gram-negative enteric bacteria is the most common pathogen. Urine culture is the basic investigation that allow to identify pathogen and its drug sensitiveness but simultaneous urinalysis is necessary to recognize the inflammation of urinary organs. In addition, the number of leukocytes gives an idea about inflammation intensity. Ultrasonographic (USG) scan is necessary to examine urostasis. DMSA study performed during febrile UTI allow to identify children with acute pyelonephritis and when repeated 6 months later - those with renal scars. A normal USG and DMSA scan during infection makes voiding cystourethrography (VCU) unnecessary in the primary examination. The presence of vesicoureteric reflux (VUR) not always predispose children to renal lesions. Early and appropriate treatment of UTI, especially during the first 24 hours, diminishes the likelihood of renal involvement during the acute phase of infection but does not prevent scar formation. The proper hygiene of the urethral meatus, voiding and drinking habits and preventing of constipation are crucial in UTI prophylaxis.
