“…The authors analyzed 124 patients who underwent LDN, 83 patients with a single artery, 33 with two arteries and 8 with three arteries, with 1-year graft survival rates of 96.1%, 90.9% and 90%, respectively (17). Similar results were published by other authors (16,17,19). In the other hand, Paramesh et al when analyzing 278 LDN during a 10-year period, showed in a multivariable logistic regression analysis that MA was an independent risk factor for acute rejection.…”

ARTIcLE INFO _________________________________________________________ ___________________Purpose: We evaluated our experience with laparoscopic donor nephrectomy in patients with multiple renal arteries, comparing operative outcomes and early graft function with patients with a single renal artery. Materials and Methods:From January 2003 to February 2009, 130 patients underwent laparoscopic donor nephrectomy at our institution, 108 (83%) with a single renal artery and 22 (17%) with multiple arteries. Donor and recipient outcomes for single artery and multiple arteries allografts were compared. Results: The LDN operative time was similar between the single artery and multiple arteries groups (162 vs 163 min, respectively, p = 0.87). Allografts with multiple arteries had significantly longer warm ischemia time (3.9 vs 4.9 min, p = 0.05) and cold ischemia time (72 vs 94 min, p < 0.001) than those with single artery. The conversion rate was similar between single and multiple arteries groups (6% vs 4.5%, respectively, p = 0.7). Multiple arteries grafts had a non statistically significant higher rate of poor graft function when compared to single artery grafts (23% vs 12%, respectively, p = 0.18). Five patients in the single artery group (4.6%) and one patient in the multiple arteries group (4.5%) needed dialysis during the first postoperative week. Overall, recipient complication rates were similar between single and multiple arteries groups (12.9% vs 18.1%, respectively, p = 0.51). Conclusion: Laparoscopic donor nephrectomy with multiple arteries was associated with a non statistically significant higher rate of poor early graft function. The procedure appears to be safe in patients with multiple arteries, with similar complications rates. Multiple arteries should not be a contraindication for laparoscopic donor nephrectomy.

OBJETIVO: Verificar a prevalência e a distribuição das artérias renais e de seus ramos in vivo, relacionando as particularidades encontradas nas artérias renais com o sexo e sua lateralidade. MÉTODO: Duzentos pedículos renais foram estudados por meio de angiotomografias e suas artérias analisadas de acordo com número, posição de origem, calibre, comprimento e trajeto em relação aos segmentos renais. Sua frequência e lateralidade foram pesquisadas quanto ao sexo e idade. RESULTADOS: Foram observadas múltiplas artérias em 61,5% dos pedículos (56% à direita e 67% à esquerda), ocorrendo em 65% dos homens e 58% das mulheres. A origem aórtica para as múltiplas artérias foi mais frequente à direita e, com maior frequência, as artérias renais se originaram entre as vértebras L1 e L2 como divisões pré-hilares da artéria principal. O comprimento médio da artéria principal foi maior em rins direitos com artéria única. Não houve diferença entre o diâmetro da artéria renal principal. CONCLUSÃO: Existe maior prevalência das múltiplas artérias renais do que aquela descrita na literatura, sem diferença entre os sexos ou lateralidade. As artérias renais originaram-se com maior frequência entre as vértebras L1 e L2, como divisões pré-hilares da artéria principal e com trajeto ao hilo do rim. O comprimento médio da artéria principal é maior à direita e nos rins com artéria única. Não houve diferença no diâmetro da artéria renal principal entre rins com artérias únicas e múltiplas.

“…However, arteries supplying the lower pole of the kidney must be preserved and reconstructed to avoid compromising blood flow grafts with MRA had no incidence of thrombosis [21]. Additional morbidities documented as being associated with MRA grafts include prolonged ischaemic time resulting in higher incidence of acute tubular necrosis, DGF and increased risk of rejection.…”

Multiple Renal Arteries in Live Donor Renal Transplantation; Impact on Graft Function and Outcome: A Prospective Cohort Study

Introduction: The presence of multiple renal arteries (MRA) in the donor allograft was once a contraindication to transplantation. Despite concerns about risks, these allografts are being increasingly used to overcome a shortage of renal donors. Objectives: To compare the outcomes of live-donor renal allografts with multiple and single renal arteries (SRA) in terms of overall ischemia times, early and late graft function, and vascular and urological complications. Methods: A prospective, non-randomized cohort study was conducted including all live donor renal transplants done by the Vascular and Transplant
