Abstract
In renal vascular anatomy, compared to the regular presence of the main renal artery, one or more additional renal arteries unilaterally or bilaterally are the commonest arterial anatomical variation of the kidneys. The influence of multiple renal arteries (MRA) graft on the vascular transplant and the clinical outcome is not well established.

In renal vascular anatomy, compared to the regular presence of the main renal artery, one or more additional renal arteries unilaterally or bilaterally are the commonest arterial anatomical variation of the kidneys
Contradictory results have been reported if the use of kidney allografts with multiple renal arteries (MRA) adversely affects post-transplant graft and patient outcome or increases the incidence of vascular and urologic complications compared with the use of grafts with a single renal artery (SRA)
In 2007 Gawish and coll., reported their experience in Kuwait in 35 renal transplants with MRA; they concluded that transplantation of MRA grafts might carry a relatively higher risk for complications, it is justified because it gives results comparable with those achieved in SRA [1]
