Use of the vena cava to extend the right renal vein for cadaver transplantation is controversial. Right renal vein extension permits an easier anastomosis and possibly better positioning of the kidney, but may create a low flow or turbulent state. We studied whether use of a vein extension had an impact on outcome. Between January 1986 and April 1993, 305 cadaver transplant recipients received a right kidney. Of these, 76 received a graft with vein extension. None of the 76 experienced technical vascular complications versus 5 of the 229 (2.2%) without vein extension. There was no difference in 1- and 2-year graft survival for those with versus without extension. We conclude that there is no increased risk with use of the vena cava extension and recommend that the donor team routinely provide the right kidney with the vena cava attached. This allows the recipient team to determine whether an extension is appropriate for the particular recipient.
