Variations in initial renal transplant function by type of organ retrieval.

Area of Science:

• Nephrology
• Transplant Surgery
• Organ Donation

Background:

• Numerous factors influence early kidney function and graft survival post-transplantation.
• Limited data exist comparing outcomes based on single versus multiorgan donation types.
• Understanding retrieval type impact is crucial for optimizing renal graft outcomes.

Purpose of the Study:

• To analyze the association between the type of organ retrieval and early renal graft function.
• To investigate the relationship between kidney-only (KO), kidney-liver (KL), and multiorgan (MO) retrievals and delayed graft function (DGF) and early graft failure (EGF).

Main Methods:

• Retrospective analysis of 287 kidney transplantations from deceased donors (2004-2012).
• Categorization of retrievals into kidney-only (KO), kidney-liver (KL), and multiorgan (MO).
• Univariate and multivariate logistic regression analyses to assess DGF and EGF associations with retrieval type.

Main Results:

• Delayed graft function (DGF) rates were similar across retrieval types (KO 20.5%, KL 24%, MO 25.8%).
• Early graft failure (EGF) at 3 months was significantly higher in kidney-only (KO) retrievals (17.6%) compared to multiorgan (MO) retrievals (5.3%).
• Multivariate analysis identified donor age and sex as significant factors for DGF, but not retrieval type; however, KO retrieval was significantly linked to EGF.

Conclusions:

• Early graft function at 3 months is reduced in kidney-only retrievals compared to multiorgan retrievals.
• This difference may be attributed to less favorable donor and recipient characteristics associated with kidney-only retrievals.
• The type of organ retrieval, particularly kidney-only, is a significant factor in early kidney transplant outcomes.
