Brief summary

In this retrospective study, the authors assess long term renal outcome in renal transplant recipients after cardiac surgery with cardiopulmonary bypass, and research factors associated with poor long term renal outcome.

Detailed description

Post-operative mortality after cardiac surgery is increased in renal transplant recipients, compared with general population of cardiac surgery, or with kidney transplant recipients not undergoing cardiac surgery. If the survival of this specific population is now well studied, the long-term renal outcome is much less studied. Previous studies show a trend for increased risk of allograft dysfunction and need for permanent dialysis. This study proposes to compare long term renal outcome between renal transplant recipients and non-renal transplant recipients.
