Swiss consensus recommendations on urinary tract infections in children

Area of Science:

• Pediatrics
• Infectious Diseases
• Nephrology
• Urology

Background:

• Urinary tract infections (UTI) are common in children, with fever often indicating pyelonephritis, though distinguishing upper from lower UTI can be challenging in young children.
• Congenital anomalies of the kidney and urinary tract (CAKUT) and bladder-bowel dysfunction are significant risk factors for long-term sequelae after UTI.
• Vesicoureteric reflux (VUR) is a risk factor for UTI but not solely responsible for renal scarring.

Purpose of the Study:

• To develop multidisciplinary Swiss consensus recommendations for the diagnosis and management of pediatric urinary tract infections.
• To provide clear guidance on diagnosis, therapy, imaging indications, and antibiotic prophylaxis based on current data and international guidelines.

Main Methods:

• Development of consensus recommendations by Swiss pediatric infectious diseases, nephrology, and urology societies.
• Review of recent data and international guidelines on pediatric UTI management.
• Incorporation of clinical considerations regarding age, risk factors, and pathogen sensitivity.

Main Results:

• UTI diagnosis requires urinalysis and urine culture; differentiation between upper and lower UTI is crucial.
• Renal ultrasound is recommended after pyelonephritis in all children.
• Antibiotic prophylaxis is generally not recommended; invasive imaging indications are more restrictive.

Conclusions:

• Congenital anomalies of the kidney and urinary tract (CAKUT) and bladder-bowel dysfunction are more critical for long-term sequelae than VUR alone.
• Switching to oral antibiotics early, even in young infants, is advised.
• Recommendations cover diagnosis, treatment duration, antimicrobial options, imaging, and prophylaxis for pediatric UTI.
