Pelvic Kidney With Contralateral Renal Vascular Variants: A Rare Anatomical Case From Djibouti.

A pelvic kidney is a rare congenital renal ectopia frequently associated with vascular anomalies. Knowledge of these variations is essential for diagnostic evaluation and surgical planning. We report the case of a 35-year-old man in whom a right pelvic kidney with unusual vascular variations was detected on computed tomography urography. A single renal artery arising from the anterior aspect of the aortic bifurcation supplied the ectopic kidney, which was drained by three right renal veins. In addition, the contralateral kidney, located in its normal anatomical position, also exhibited vascular variations, including two left renal arteries and two left renal veins. Pelvic kidneys are often associated with complex vascular patterns, as demonstrated here. Therefore, knowledge of these anatomical variations is crucial for accurate diagnosis and for safe surgical or interventional procedures, particularly in the management of renal vascular diseases and in the context of kidney transplantation.
