Resumo
Variações na vascularização renal e na artéria testicular são comuns no corpo humano. No entanto, cálices extrarrenais e artérias renais anteriores à veia cava são incomuns. No presente caso, relatamos a presença de cálices extrarrenais em ambos os rins, duas artérias renais direitas anteriores à veia cava e uma artéria testicular direita aberrante. Os rins e as gônadas se desenvolvem a partir do mesoderma intermediário. As artérias que os irrigam se originam da aorta dorsal. Esse plexo vascular é disposto de forma semelhante a uma escada devido à ascensão dos rins e à descida das gônadas. Qualquer variação no suprimento vascular dessas estruturas deve estar inter-relacionada; por isso, procurou-se esclarecer o aspecto embriológico dessas variações.
