A sustainable approach to radiologic follow-up in pediatric UTIs prioritizes selective imaging based on evidence-based guidelines. The goal is to enhance diagnostic accuracy while reducing unnecessary radiation exposure and invasive procedures. Ultrasound remains the primary modality of choice, with more invasive imaging reserved for high-risk patients based on clinical criteria.

Emerging technologies, particularly AI-driven imaging analysis, offer potential to refine diagnostic workflows and improve decision-making. Future research should focus on refining risk stratification models, optimizing imaging protocols, and integrating non-invasive approaches to enhance patient safety and healthcare efficiency.

By adopting a judicious, evidence-based approach, clinicians can improve long-term renal outcomes for pediatric patients while aligning with principles of sustainable and cost-effective healthcare.
