Bilateral variations of the testicular vessels: Embryological background and clinical implications

Variations of the testicular vessels were observed during routine dissection of the posterior abdominal wall in a male North Indian cadaver. On the right side, the testicular vein drained into the right renal vein and the right testicular artery passed posterior to the inferior vena cava. The left testicular vein was composed of the lateral and medial testicular veins which drained into the left renal vein independently. Left renal vein had received an additional tributary, first lumbar vein, and the left testicular artery had hooked this additional tributary to run along its normal course.
