Abstract
We demonstrate an aberrant ramification pattern of the renal and testicular vessels. On both sides, the anterior and posterior renal veins emerged from the renal. On the right side, the anterior renal vein collected the right testicular vein and drained into the inferior vena cava, while the posterior one directly drained into the inferior vena cava. Two retrocaval testicular arteries originated from the aorta. On the left side, the perinephric vein drained from the abdominal wall and adrenal gland and joined the anterior renal vein. The anterior renal vein also collected the testicular, suprarenal, and inferior phrenic veins. The posterior one received the other testicular vein and the first three lumbar veins. These renal veins converged, passed anteriorly to the aorta, and drained into the inferior vena cava. Knowledge of the varied anatomy of these vessels will contribute to safe surgical approach to the kidneys.
