EAU guidelines on vesicoureteral reflux in children.

Area of Science:

• Pediatric Urology
• Nephrology
• Congenital Abnormalities

Background:

• Primary vesicoureteral reflux (VUR) is a common congenital urinary tract abnormality in children.
• Management strategies for VUR remain controversial, with a primary goal of preserving kidney function.
• Early identification of children requiring intervention is crucial for optimal outcomes.

Purpose of the Study:

• To propose a management approach for pediatric VUR based on early risk stratification.
• To guide clinicians in identifying children at higher risk for renal damage and recurrent infections.
• To balance the need for intervention with the risk of overtreatment for clinically insignificant VUR.

Main Methods:

• A comprehensive literature search and data review were conducted.
• Risk factors for VUR progression and renal scarring were analyzed, including family history, gender, VUR grade, and voiding dysfunction.
• Standard diagnostic imaging and urodynamic studies were evaluated for their role in risk stratification.

Main Results:

• Key risk factors for VUR include family history, gender, laterality, age, presenting symptoms, VUR grade, duplication, and voiding dysfunction.
• Early risk stratification aids in identifying patients prone to renal scarring and urinary tract infections (UTIs).
• Conservative management (antibiotics, bladder rehabilitation) and interventional therapies (bulking agents, reimplantation) are discussed.

Conclusions:

• A balanced approach is essential, distinguishing between clinically insignificant VUR and cases requiring immediate intervention.
• Early screening of siblings and offspring of affected children is recommended.
• Preventing febrile UTIs is paramount, as VUR itself does not damage kidneys when infection-free.
