To the Editor,
We read with great interest the article by Kamali et al [1] entitled "Renal transplantation in allografts with multiple versus single renal arteries," published in your valuable journal. This retrospective study focused its message on whether grafts with multiple renal arteries (MRAs) have impact on the outcome of living donor kidney transplantation. Delayed graft function (DGF) was more frequently seen in patients with grafts having MRAs compared to those who received grafts with single renal artery (SRA), [1] which was consistent with other reports. [2],[3] Although it is reasonable that presence of MRAs may lead to increase in operation time which may contribute to the development of DGF, we found no significant difference in the warm ischemia time between recipients with MRAs and patients with SRA. [4] Overall, warm and cold ischemia times in our previous report were shorter than those reported in other studies. [2],[5],[6]
It is of interest that Kamali et al [1] did not find a higher rate of acute rejection in recipients with MRAs when compared to patients receiving allografts with SRA, which was consistent with the report of Benedetti and co-workers. [7] However, the incidence of acute rejection episodes was significantly higher in the MRAs' group than the SRA group among our patients. [4]
In addition, renal artery stenosis (RAS) was more likely to occur in patients receiving kidneys with MRAs than SRA, [1] which was similar to that reported earlier. [8],[9] However, Kamali et al [1] found no significant differences in the occurrence of postoperative complications such as renal artery thrombosis and hematoma in the two groups, as has been reported by previous studies; [4],[7] it can be attributed to the fact that multiple arteries were converted to a single artery by bench reconstruction. [7] In contrast, a number of investigations carried out previously have suggested that grafts with MRAs are associated with a higher risk for vascular complications, especially hemorrhagic complications and arterial thrombosis. [3],[8],[10],[11],[12]
We agree that patients receiving kidneys with MRAs have a favorable short-term patient and graft outcome. [1],[7],[8],[13] Although we showed that using grafts with two arteries is safe and yielded the same 1-year patient and graft survival as those with SRA, grafts with three arteries had unfavorable outcome, [4] which was consistent with other reports. [5],[6],[8]
Some authors have previously reported that kidneys with MRAs are a relative contraindication for transplantation because of the increased incidence of vascular and urologic complications. [10],[12] However, other studies have indicated that living donor kidney transplantation using grafts with MRAs is safe and results in acceptable patient and allograft outcome. [1],[4],[5],[6],[8]
