The testicular vein exhibits variations in number, course, and insertion. Such differences may enhance the risk of varicocele and complication in patients by impairing testicular drainage. The following is a case report of the abnormal drainage of the right testicular vein (RTV) draining into the right renal vein (RRV). The incidence, course, insertion, and termination angle of the testicular veins were measured with a 150 mm digital Vernier dial microcaliper, and photographs were taken by Canon EOS 70D using a 100mm macro lens. In one out of seven cadavers (14.28%), the right testicular vein (RTV) drained into the right renal vein (RRV) (Type III) rather than into the inferior vena cava (IVC) at a 90° angle 0.4 cm from the IVC. The double (medial and lateral) left testicular veins (LTV) drained into the left renal vein (LRV) at a 62° angle 5 cm from the IVC. The understanding of type III RTV drainage or course can provide crucial data for surgeons in order to prevent complications during right-sided varicocele surgery.
