“…Some reports have indicated that the lymphatic cysts are more likely to occur when there are multiple renal arteries (22)(23)(24). This is likely because of the large number of lymphatic vessels around the renal hilum.…”

OBJECTIVE.: Renal transplantation is generally accepted as one of the most effective treatment options for the end-stage renal disease. However, donor kidneys with multiple renal arteries represent a surgical challenge. For these cases, the surgical strategy is to directly anastomose multiple renal arteries to the internal iliac artery or the external iliac artery. However, this approach is complicated by the difficulty in performing the anastomoses, bleeding, stenosis, and a high incidence of false aneurysms. METHODS.: By applying the method of ex vivo reconstruction of the donor renal artery with the recipient internal iliac artery, we repaired five cases of donor kidneys with more than three renal arteries and excessively short renal arteries during transplantation and treated three cases of renal aneurysms with renal autotransplantation. RESULTS.: In all the cases, the surgery was without complications. At a minimum follow-up of 4 years, all patients showed normal renal function, and color Doppler ultrasonography indicated no thrombus or aneurysm formation or obstruction in the renal artery or its branches. CONCLUSIONS.: The ex vivo reconstruction of the donor renal artery with the recipient internal iliac artery is a feasible and effective surgical procedure for the transplantation of donor kidneys with multiple renal arteries and the autotransplantation of kidneys for the treatment of renal artery aneurysms.

“…Authors of these studies did not find differences in the outcomes when comparing the patients who received a multiple artery graft with those who received a single pedicle kidney (1, 10-16). Some authors even concluded that every anomaly or injury in the extraction had to be overcome in bench surgery (4).…”

BackgroundMultiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. Our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft.ObjectivesTo find our the differences in the outcome and complications in patients undergoing kidney transplantation with one single artery or with multiple arteries.Patients and MethodsWe analyzed 147 kidney transplantations, (all performed in our hospital over a 3 year period). population divided into two groups: group A for those who presented with only one renal artery, or group B for those with more than one renal artery. Homogeneous vascular reconstructions and implantation rules were applied in all patients. We compared the rates of renal failure between the two groups, urinary and vascular complications, patient and graft survivals and the levels of creatinine clearance during the first year of post-transplantation.ResultsNo significant differences were found between the two groups regarding to the values analyzed.ConclusionsAs many other authors, we do believe that the presence of multiple renal arteries in kidney grafts should not be considered as a predictive factor of transplantation failure.

“…The frequency of MRAs is between 18 and 30% in cadaveric series and these can be successfully transplanted even with laparoscopy [4] . In renal allotransplantations with MRA kidney the ischemia period is lengthened and there is the need to anastomose more than one vessel resulting in theoretically higher rates of complications and rejections.…”

Aim: To evaluate the effect of multiple renal artery (MRA) presence on the success and complication rate of renal allotransplantation. Patients and Methods: We retrospectively analyzed 187 cases (128 men and 59 women) who were transplanted in our department from 1997 to 2005. 28 of these cases had MRA. Of MRA kidneys, 6 were obtained from cadavers and 22 from live donors. When the types of anastomoses for MRA cases were examined, 4 cases were anastomosed after being connected to the main polar artery with ex vivo bench surgery; the others had in vivo anastomosis. The patients were divided into two groups as single (group 1) and MRA (group 2) groups. Following the transplantation, creatinine levels, ATN ratios, development of hypertension, patient and graft survivals and vascular and urological complications were compared between the two groups. Results: Patient and graft survival rates were compared between the two groups in the first and third post-operative years. In the first year, graft survival rates for groups 1 and 2 were 94.9 and 92.9% respectively, whereas in the third year these were calculated as 88 and 85.7%. Concerning patient survival, first year results for groups 1 and 2 were 92.5 and 89.2%, for the third year these were found to be 84.9 and 82.1%. Mean creatinine levels of both groups were compared in the first and third years. The results for groups 1 and 2 were 1.41 ± 0.37 and 1.46 ± 0.46 mg/dl respectively for the first year. In the third year these were found to be 1.60 ± 0.43 and 1.69 ± 0.49 mg/dl and there was no statistically significant difference between the groups. Vascular and urological complications were observed in only 6 out of 187 cases (3.2%). Conclusions: No significant difference has been observed between single and MRA kidneys considering the success and complication rates of renal allotransplantation.
