Outcomes of Transrenal Artery Perfusion Versus Transrenal Vein Perfusion Using LifePort for Deceased Donor Kidney Transplantation

West China Hospital108 enrolled

Overview

The main objective of this study is to compare the outcomes of transrenal artery perfusion versus transrenal vein perfusion using LifePort for deceased donor kidney transplantation. Patients registered in the National Dialysis and Transplant Registry awaiting deceased donor kidney transplantation were included. Delayed graft function (DGF) or primary nonfunction (PNF) may occur after deceased donor kidney transplantation. Compared with static cold storage, the application of LifePort can significantly reduce the incidence of DGF and PNF in deceased donor kidney transplantation. Transrenal artery perfusion is currently the mainstream but confronts multiple renal arteries, resulted in prolonged cold ischemia time. Transrenal vein perfusion is expected to be a solution. However, whether the clinical outcomes of transrenal vein perfusion is inferior to transrenal artery perfusion remains unknown. In this study, values of urine volume and creatinine, incidence and duration of DGF, and incidence of PNF within 1 week after surgery are recorded and compared between the transrenal artery perfusion group and the transrenal vein perfusion group. Monthly eGFR and creatinine values, the incidence of acute rejection within 1 year after transplantation and 1-year graft and patient survival are also recorded and compared.

Outcomes

Primary Outcomes

Delayed graft function

Delayed graft function is defined as the need for dialysis (for any cause) within the first week posttransplantation.

Time frame: Within one week posttransplantation

Secondary Outcomes

Graft loss

Graft loss was defined as re-establishment of long-term dialysis or estimated glomerular filtration rate (eGFR) of \<15 ml/min.

Time frame: One year after transplantation

biopsy-confirmed acute rejection

biopsy-confirmed acute rejection was diagnosed clinically based on a significant increase in serum creatinine levels of 50% or more within 3 days, which was not explained by other reasons and confirmed by biopsy.
