Abstract

Variations in the renal vasculature and testicular artery are common within the human body. However, extra renal calyces and precaval renal arteries are uncommon. In the present case we report extra renal calyces of both kidneys, two right precaval renal arteries, and an abnormal right testicular artery. The kidneys and gonads develop from the intermediate mesoderm. The arteries supplying them bud from the dorsal aorta. This vascular plexus is arranged in a ladder-like manner due to the ascent of kidneys and descent of gonads. Any variation in the vascular supply of these structures must be interrelated, hence care has been taken to clarify the embryological aspect of these variations.

Keywords

renal vascular variation; extrarenal calyces; precaval renal artery; accessory renal arteries

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.

Palavras-chave
