Outcome of kidney transplantation from living donors with multiple renal arteries versus single renal artery

Receiving a kidney transplant from donors with
multiple renal arteries (MRAs) is suggested to be associated with
higher risk of vascular and urologic complications and poor allograft
outcomes compared to the donors with single renal artery (SRA).
We evaluated survival rates in the recipients from donors with
MRAs compared to those from donors with SRA.
Materials and Methods. In a retrospective study on 115 kidney
allograft recipients, demographic characteristics and the outcomes
of kidney transplantation were compared between the recipients
from donors with MRAs compared to those from donors with SRA.
These included acute tubular necrosis, acute allograft rejection,
hypertension, vascular complications, urologic complications,
kidney function indicators, and allograft survival at 1 year.
Results. There was no significant difference in the recipients’ age,
sex distribution, and weight, donors’ age, donor-recipient familial
relation, urologic complications, and duration of hospitalization
between the two groups. However, MRA was significantly associated
with a higher likelihood of right-side kidney donation, longer
warm and cold ischemia times, and lower glomerular filtration
rate and higher serum creatinine concentrations at discharge and
12 months after transplantation, as compared to SRA transplants.
No significant difference was seen in late complications including
hypertension and renal artery stenosis. One-year graft survival was
slightly poorer in the MRA group than the SRA group.
Conclusions. Our results demonstrate that kidney allografts with
MRAs are associated with risks but have acceptable outcomes
during the 1st year after transplantation, as compared to SRA
kidney allografts
