Renal vascular deformity (RVD) happens during the embryonic period when kidneys ascend into the lumber region. However, the exact etiology of this deformity remains unknown. RVD is not a rare congenital anomaly in urology as many cases with vascular deformity have been reported.However, no case has been reported with unilateral kidney almost in the normal position, but with several different branches of ectopic arteries-one even receiving the arterial supply from the contralateral iliac artery-and ectopic veins, one of which forms a collateral circulation with the portal vein. Moreover, it is quite interesting that this case of RVD is combined with another abnormality-duplex pelvis and renal malrotation. We will present this extremely rare case of multiple malformation of the right renal vascular deformity combined with duplex pelvis and malrotation.
