Abnormal ramification pattern of the renal and testicular vessels

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