INTRODUCTION: Persistent urinary extravasation after high-grade renal trauma is uncommon but may require intervention. Minimally invasive, kidney-preserving options are particularly desirable in young patients.
CASE PRESENTATION: An 18-year-old man sustained blunt trauma in a motorcycle accident. Contrast-enhanced computed tomography revealed renal injury with urinary extravasation. Emergency transcatheter arterial embolization was performed for hemorrhage control. Despite subsequent ureteral stenting and percutaneous drainage, urinary leakage persisted. Fistulography demonstrated a small fistulous tract between the urinoma cavity and the lower calyx. Selective embolization using N-butyl-2-cyanoacrylate (NBCA) was performed, resulting in immediate resolution without complications.
CONCLUSION: Selective NBCA embolization is a safe and minimally invasive treatment option for persistent urinary fistula after renal trauma.
