ABSTRACT

Background: The kidneys lie in the retroperitoneal space on the posterior abdominal wall on either side of the T12-L3 vertebrae.The right kidney usually lies more inferior than the left kidney because of the presence of the liver on the right side. Congenital variations of the testicular vein include variation in the course, areas of drainage and termination. The anatomical variations of the testicular veins are attributed mainly to their embryologic origin. The right testicular vein usually drains into IVC just below the renal vein, but sometimes drains into the right renal vein. In the present study, bilateral variations of the testicular vessels were observed and these variations are of some clinical significance. The bifurcated right testicular vein might be a predisposing factor for the right sided varicocele.
Materials and Methods: Presenting variations were found at the department of anatomy, Southern Medical University, Guangzhou P.R, China, during our routine Anatomy dissections.
Discussion: The right testicular vein drains blood into the inferior vena cava, while the left testicular veins drains into the left renal vein. The anomaly discovered was that both the left and right testicular veins drained into the left renal vein. Testicular venous drainage is done through the pampiniform plexus, which in the region of the internal inguinal ring gives pathway to the testicular vein. The left testicular vein discharges in the left renal vein in a straight angle, whereas the right testicular vein discharges directly in the inferior vena cava in an oblique angleAn anomalous path of the right testicular vein was observed on the cadaver. In our dissections also we identified The right testicular vein bifurcated into two veins just before its termination and both the branches terminated into Right renal vein instead the inferior vena cava during our dissections and as usual the left testicular vein drained into Left renal vein.
Conclusion:  The Variations can influence testicular drainage and even lead to varicocele, one of the causes of male infertility. Variations in the number and in the local of termination are frequent. Abnormalities of testicular vessels may lead to loss of gametogenesis and hormone Production. Testicular vessels may be clinically, radiologically, surgically and functionally important.
Key words: Testis, Right Testicular Vein, Inferior Vena Cava, Right Renal Vein.
