Urinary tract infections in infants and children: Diagnosis and management
Insights
Diagnosing and managing pediatric urinary tract infections (UTIs) involves specific urine collection methods and imaging. Prompt antibiotic treatment is crucial for febrile UTIs, with targeted investigations based on ultrasound findings.
Area of Science:
- Pediatric Nephrology
- Infectious Diseases
- Urology
Background:
- Urinary tract infections (UTIs) are common in children, necessitating updated management guidelines.
- This statement addresses acute UTIs in children over two months without pre-existing urinary tract issues.
Purpose of the Study:
- To outline current best practices for diagnosing and managing acute UTIs in pediatric patients.
- To provide guidance on urine sample collection, antibiotic therapy, and diagnostic imaging.
Main Methods:
- Review of recent studies and clinical guidelines on pediatric UTIs.
- Recommendations for urine sample collection (catheter, suprapubic aspirate, midstream).
- Guidelines for antibiotic duration and route of administration.
Main Results:
- Urinalysis is key; a normal result makes UTI unlikely. Bagged samples are unsuitable for culture.
- Febrile UTIs require 7-10 days of antibiotics; oral treatment is viable for non-critically ill children.
- Renal/bladder ultrasound is recommended after the first febrile UTI in children under two.
Conclusions:
- Diagnostic criteria and urine collection methods are critical for accurate UTI diagnosis in children.
- Imaging (ultrasound) is indicated for specific cases, while voiding cystourethrograms are reserved for select findings.
- Adherence to these guidelines ensures appropriate management and reduces potential complications of pediatric UTIs.
Abstract:
Recent studies have resulted in major changes in the management of urinary tract infections (UTIs) in children. The present statement focuses on the diagnosis and management of infants and children >2 months of age with an acute UTI and no known underlying urinary tract pathology or risk factors for a neurogenic bladder. UTI should be ruled out in preverbal children with unexplained fever and in older children with symptoms suggestive of UTI (dysuria, urinary frequency, hematuria, abdominal pain, back pain or new daytime incontinence). A midstream urine sample should be collected for urinalysis and culture in toilet-trained children; others should have urine collected by catheter or by suprapubic aspirate. UTI is unlikely if the urinalysis is completely normal. A bagged urine sample may be used for urinalysis but should not be used for urine culture. Antibiotic treatment for seven to 10 days is recommended for febrile UTI. Oral antibiotics may be offered as initial treatment when the child is not seriously ill and is likely to receive and tolerate every dose. Children <2 years of age should be investigated after their first febrile UTI with a renal/bladder ultrasound to identify any significant renal abnormalities. A voiding cystourethrogram is not required for children with a first UTI unless the renal/bladder ultrasound reveals findings suggestive of vesicoureteral reflux, selected renal anomalies or obstructive uropathy.
