A comparison of the results of renal transplantation from non–heart-beating, conventional cadaveric, and living donors.

Background

In an attempt to address the shortage of conventional kidney donors, a non–heart-beating donor (NHBD) organ retrieval program has been established. We compared the results of kidney transplants from NHBDs (N = 77) with those from heart-beating cadaveric (HBD; N = 224) and living donors (LD; N = 49), performed in the same eight-year period.

Methods

Patients dying after failed attempts at resuscitation in the accident department or after intracerebral hemorrhage/anoxia were considered as potential NHBDs. After death, in situ kidney perfusion and cooling were achieved using an intra-aortic catheter inserted via a femoral artery cut down. Kidney retrieval and transplant operations were performed using standard techniques.

Results

The median (range) warm ischemic time for NHBD kidneys was 25 minutes (5 to 53 min). The initial function rates for NHBD, HBD, and LD transplants were 6.5, 76.3, and 93%, respectively. Primary nonfunction occurred in 5 of 75 evaluable NHBD transplants (7%) compared with only 6 out of 224 (2.7%) HBD and 1 out of 49 (2%) LD transplants (P = NS). Eighty-four percent of NHBD kidney recipients required postoperative dialysis for a median of 19 days. The mean (SD) serum creatinine at 12 months was 179 (73) μmol/L in NHBD kidneys compared with 152 (57) μmol/L for HBD kidneys and 138 (44) μmol/L for LD kidneys. The actuarial five-year graft survival rates for NHBD, HBD, and LD transplants were 79, 75, and 78%, respectively. During the period under study, NHBD organs accounted for 22% of the total renal transplant program.

Conclusions

Despite being associated with poor initial graft function, the long-term allograft survival of NHBD kidneys does not differ significantly from the results of HBD and LD transplants.
