PURPOSE: The critical organ shortage has increased demand for marginal donor kidneys. Although previously a contraindication to live kidney donation, advanced age donors (>60 y.o.) have become more common, raising concerns about their long-term health.
METHODOLOGY: All donor and recipient records of DN performed between 1975 and 2014 were reviewed. Donor and recipient demographics, intraoperative parameters, complications, and short- and long-term outcomes were compared between contemporaneous donors >60 y.o. and <60 y.o. in a matched-control design.
RESULTS: Between 1975 and 2014, we performed 3,752 DN: 2,275 open (ODN), 1,477 laparoscopic DN (LDN). Among donors, 167 (4.5%) were >60 y.o. On univariate analysis, >60 y.o. donors were more likely to have had prior abdominal surgery (p<0.001) and have documented hypertension (p<0.001); and less likely to smoke (p<0.001). Baseline estimated glomerular filtration rate (eGFR) was different between >60 y.o. (80+16) and <60 y.o. donors (101+26; p<0.001). Intraoperative and post-operative complications were similar among the 2 groups, with the exception of <30 day ileus, which was more frequent among >60 y.o. donors (p=0.02). Post-operative Length of stay (LOS) was longer for >60 y.o. donors (p=0.005). On multivariate analysis, <30 day ileus (HR 1.50, 95%CI 1.28-1.77) and LOS (HR 0.4, 95%CI 0.2-0.7) were greater for >60 y.o. donors. After >20 years post-DN, systolic blood pressure was significantly higher among >60 y.o. donors (142+21 vs 125+16; p<0.001) and HTN was diagnosed earlier post-DN (9 vs 14 years; p<0.001). Estimated glomerular filtration rate (eGFR) was significantly lower for >60 y.o. donors (Figure 1) but slope of eGFR or rates of end-stage renal disease (ESRD) did not seem to be significantly different >20 years after DN (p=0.26).
CONCLUSION: Kidney donation among carefully-selected >60 y.o. donors poses minimal perioperative risks and a no added risk of ESRD.
