Adolescent idiopathic ureteral stricture: A multimodal diagnostic and surgical approach in resolving hydronephrosis

This case highlights chronic inflammation as a potential driver of idiopathic ureteral strictures in adolescents, contrasting with fibrosis-dominated adult cases. It validates multimodal imaging and surgical resection as effective diagnostic and therapeutic strategies while emphasizing anatomical vulnerability at the fifth lumbar vertebra. The findings advocate for pediatric-focused research to explore inflammatory biomarkers, genetic predispositions, and minimally invasive alternatives.
