title: The impact of the pre-transplant renal replacement modality on outcome after cadaveric kidney transplantation: the ghent experience.
abstract: For suitable patients, renal transplantation is still the most preferable renal replacement modality, offering the best outcome in terms of survival and quality of life [Meier-Kriesche, H.U. et al: Semin Dial 2005;18:499-504]. The shorter the period on dialysis, the better the outcome after transplantation seems to be [Meier-Kriesche, H.U. et al: Transplantation 2002;74: 1377-1381]. However, for most patients, a pre-emptive transplantation is not an option by lack of a suitable organ. Therefore, most people have to undergo hemodialysis or peritoneal dialysis (PD) while awaiting a donor kidney. There is evidence that PD positively impacts on the outcome after transplantation [Van Loo, A.A. et al: J Am Soc Nephrol 1998;9:473-481], an effect that could be attributed to a more stable fluid homeostasis, but also to an independent effect of biocompatibility of the dialysis membrane [Van Biesen, W. et al: Transplantation 2000;69:508-514], which is by definition better in PD. Based on these findings, since 1999, all hemodialysis patients at the university of Ghent are dialyzed on a low complement activating dialyzer, and dialysis and especially ultrafiltration in the 24 h preceding the transplantation are avoided as much as possible. A recent re-analysis of the data of the outcome of our transplant program showed that this approach resulted in a reduction of delayed graft function in the hemodialysis patients, allowing to reach an outcome level comparable to that of the PD patients. However, the long-term patient survival still is slightly superior in the PD patients.
