The invasive interventions such as renal transplantation, interventional radiologic procedures and urologic operations increase awareness of the possible variations of the renal and gonadal arteries which is necessary for adequate surgical management in the aforementioned specialties. We have come across an anomalous origin of right testicular artery from right renal artery which is though not a rarity warrant attention because of the origin and course of the anomalous vessel. The origin of right testicular artery from right renal artery was obscured by inferior vena cava. This vascular variation shows a major significance in renal surgery, in partial or total nephrectomy and in renal transplant. The presence of such variations may become a major risk when this type of gonadal artery represents the single blood supply of the gonad, without a second supply from the aorta or other arterial sources. Thus it becomes imperative to report this case and discuss its embryologic and clinical aspects.
