title: Extension of right renal vein in renal transplant from deceased donors: cohort study.
abstract: OBJECTIVE
  Throughout the world, 45 000 kidney transplants are performed per year. Graft and overall survival vary according to the type of donor (living or deceased donor). Anastomosis of a short renal vein with iliac vein or common external iliac vein has been associated with technical problems such as angulation of the vein or tension on the anastomosis, which could limit visualization and control of bleeding from the graft. The main objective of our study was to analyze patients undergoing deceased-donor kidney transplant and compare results in patients who had extension of the right renal vein with a patch of vena cava from the same donor versus patients who received the left kidney.
  
  
  METHODS
  A prospective cohort study was performed from December 31, 2007 to December 31, 2009. We compared 2 patients groups. We used statistical software (R, Version 2.5.1). The analyzing team was blinded to the surgical technique, and informed consent was obtained from all patients.
  
  
  RESULTS
  There was no statistically significant difference in surgical time (P > .85) or ultrasonographic parameters between groups, but it was possible to perform an easier vein anastomosis with the vena cava graft in right kidney transplant.
  
  
  CONCLUSIONS
  We recommend considering our procedure with the vena cava graft in right kidney as an alternative option to decrease warm ischemia time, perform an easier vein anastomosis with the vena cava extension, and make the procedure comfortable for the surgeon.
