“…Thus, multi-slice Angio-CT has replaced the conventional arteriography in the evaluation and study of vascular anatomy and diagnosis of vascular diseases of the kidney. Smith et al 15 showed that Angio-CT correctly identified renal arterial anatomy in 41 out of 42 patients undergoing preoperative evaluation for nephrectomies. According to Rubin et al 16 , this method has 100% sensitivity in the identification of renal arteries.…”

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.

“…Traditionally, renal angiography and excretory urography have been used to evaluate the anatomy of renal arteries and renal function, respectively, in potential kidney donors. However, several studies have shown that helical computed tomography (CT) angiography can replace renal angiography and excretory urography in the evaluation of potential kidney donors (3)(4)(5)(6)(7)(8)(9). Hence, helical CT angiography has become an accepted method for the evaluation of living donors before they undergo laparoscopic nephrectomy.…”

Rapid Estimation of Split Renal Function in Kidney Donors using software developed for Computed Tomographic Renal Volumetry AbstractPurpose: To evaluate the speed and precision of split renal volume(SRV) measurement (SRV), which is the ratio of unilateral renal volume to bilateral renal volume, using a newly developed software for computed tomographic (CT) volumetry and to investigate the usefulness of SRV for the estimation of split renal function (SRF) in kidney donors.Method: Both dynamic CT and renal scintigraphy in 28 adult potential living renal donors were the subjects of this study. We calculated SRV using the newly developed volumetric software built into a PACS viewer (n-SRV), and compared it with SRV calculated using a conventional workstation, ZIOSOFT (z-SRV). The correlation with split renal function (SRF) using 99m Tc-DMSA scintigraphy was also investigated.Results: The time required for volumetry of bilateral kidneys with the newly developed software (16.7 ± 3.9sec) was significantly shorter than that of the workstation (102.6 ± 38.9 sec, p<0.0001). The results of n-SRV (49.7 ± 4.0%) were highly consistent with those of z-SRV (49.9 ± 3.6%), with a mean discrepancy of 0.12 ± 0.84%. The SRF also agreed well with the n-SRV, with a mean discrepancy of 0.25 ± 1.65%. The dominant side determined by SRF and n-SRV showed agreement in 26 of 28 cases (92.9%).Conclusion: The newly developed software for CT volumetry was more rapid than the conventional workstation volumetry and just as accurate, and was suggested to be useful for the estimation of SRF and thus the dominant side in kidney donors.
