Successful ex vivo renal artery reconstruction and renal autotransplantation.
BACKGROUND
The increasing experience with renal allotransplantation has led to continuing development in vascular surgical techniques. These improvements have enabled complex ex vivo renal artery surgery and renal autotransplantation to be performed. The aims of the present study were to describe the results achieved with renal autotransplantation and ex vivo renal artery reconstruction (RAR) at the Newcastle Transplant Unit, John Hunter Hospital, and to review the current indications for such surgery.


METHODS
A retrospective review was performed of patients who required renal autotransplantation with or without RAR at John Hunter Hospital, between 1991 and 1999. Data were obtained from the Newcastle Transplant Unit and the Medical Record Department of John Hunter Hospital.


RESULTS
Two patients required ex vivo RAR and renal autotransplantation for severe fibromuscular dysplasia (FMD) complicated by stenoses and renal artery branch aneurysms. The third patient required autotransplantation for bilateral retroperitoneal fibrosis. There was one postoperative complication of pelviureteric junction obstruction that was treated successfully with a temporary ureteric stent. All patients demonstrated normal graft function and were normotensive on follow up, which ranged from 2.5 to 5 years.


CONCLUSIONS
The present review confirms the long-term benefits of ex vivo RAR and renal autotransplantation that have been demonstrated by previous studies. In transplant units experienced with this surgery it has been shown to be a successful and durable technique for the treatment of a variety of vascular, urologic and other diseases.
