Background: The right and left renal veins open into the inferior vena cava at right angle. The left renal vein is 3 times longer as compared to right. The right gonadal vein (testicular in male or ovarian in female) drains directly into inferior vena cava and left gonadal vein into left renal vein.
Method: During the routine dissection teaching of posterior abdominal wall for first year MBBS students in the Department of Anatomy, MSRMC, Bangalore, we found the presence of double right renal veins along with variation in the termination of right testicular vein in an adult male cadaver aged 65 years. All the structures were carefully dissected, measurements noted and photographed using a digital camera.
Observation: In the present case, two right renal veins (superior and inferior) were found to be draining into inferior vena cava separately and right testicular vein into inferior right renal vein
Conclusion: This type of variation will help the radiologists for planning radiographic procedures; the surgeons for planning surgery to avoid intra and post-operative complications and the clinicians in recognition and protection of the variation..
