[Aneurysm repair in vitro and renal revascularization and renal autogenous transplantation for complex renal artery aneurysm in solitary kidney].
OBJECTIVE
To discuss the safety and feasibility of aneurysm repair in vitro and renal revascularization and renal autogenous transplantation for complex renal artery aneurysm in solitary kidney.


METHODS
A complex hilar renal artery aneurysm involving the bifurcation of renal artery and its branches in a solitary left kidney was diagnosed by computed tomography angiography (CTA). After temporary nephrectomy, aneurysm repair in vitro and renal revascularization were done with the kidney protected by hypothermia and continuous perfusion with preservation solution, and then the kidney was replanted into the right iliac fossa.


RESULTS
The operation was done successfully and there were no significant perioperative complications. Although a serum creatinine level temporarily exceeded above 200 micromol/L after the surgery, it recovered gradually within half a month. CTA two weeks later demonstrated patent reconstructed renal arteries and its branches and patent renal vein in the right iliac fossa, and also a patent reconstructed ureter.


CONCLUSIONS
This technique is safe and feasible to manage complex renal artery aneurysm in solitary kidney and provide an alternative for similar complex renal diseases.
