Case report describes renal avulsion misdiagnosed as ectopic kidney, highlighting critical diagnostic pitfalls.
We report a 42-year-old female with AAST Grade V renal trauma from blunt crush injury, who presented with hemodynamic stability despite surgically confirmed complete renal pedicle avulsion. Initial CT mimicked congenital ectopic kidney, risking misdiagnosis. The patient underwent emergency nephrectomy with favorable outcome. We elucidate the pathophysiology of this paradoxical phenomenon, and highlight its diagnostic pitfalls and management principles.
