A Case of Complete Renal Pedicle Avulsion With Deceptively Stable Hemodynamics: Critical Diagnostic Pitfall of Misdiagnosis as Ectopic Kidney

Key Points

To illustrate a rare case of renal pedicle avulsion presenting with stable hemodynamics, emphasizing diagnostic challenges.
Patient underwent emergency nephrectomy following a blunt crush injury.
Initial CT scan was misread as a congenital ectopic kidney.
Pathophysiology of hemodynamic stability in severe renal trauma was analyzed.
Surgical intervention confirmed complete renal pedicle avulsion.
Patient achieved a favorable outcome post-nephrectomy.
Misdiagnosis of ectopic kidney risked delay in treatment.

Abstract

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.
