Bilateral exvivo repair and kidney autotransplantation for complex renal artery aneurysms: A case report and literature review

We report the surgical management of a bilateral renal artery aneurysm diagnosed in a 41-year-old patient with a history of recurrent abdominal pain. The preoperative contrast-enhanced computed tomography showed a complex saccular aneurysm on both renal arteries within the renal hilum. The characteristics of aneurysms precluded endovascular procedures, and a double-step bilateral ex vivo reconstruction with kidney autotransplantation was planned. The intra- and postoperative period was uneventful. Imaging and laboratory examinations show preservation of renal function, and patient is symptom-free at 10-month follow up. © 2013 The Japanese Urological Association.
