Identification of an aberrant testicular vein draining the right kidney
Journal Title: International Journal of Anatomical Variations - Year 2018, Vol 11, Issue 1
Abstract
The Venous drainage of the testicles is asymmetric. The left testicular vein drains into the left renal vein while the right vein drains into the inferior vena cava (IVC). However, this textbook pattern is commonly complicated by anatomical variations in the number of veins draining each testicle and their sites of termination. Herein, we describe a specimen with three right testicular veins. The medial two veins terminated by joining the IVC. The third, lateral testicular vein coursed superiorly and laterally, received a tributary from the lateral aspect of the right kidney, and then joined the right subcostal vein. Histological examination of the vein emerging from the lateral aspect of the kidney revealed this vessel penetrated beyond the renal capsule into the renal cortex. Such a variation appears to be extremely rare, but has clinical application in surgical approaches and might provide an additional route for metastasis of testicular cancer.
