Objective: To Study 4 cases of vascular anatomy of ectopic kidneys about. Clinical cases: The first case is marked by two pelvic kidneys vascularized by an artery of homolateral iliac origin, of which that of the right gives two branches to the left kidney. The second case found a right iliac kidney vascularized mainly by a renal artery from the contralateral common iliac and two accessory arteries, one from the abdominal aorta and the other from the ipsilateral common iliac. The third case, note two iliac kidneys including that of the right received its vascularization of the abdominal aorta by two arteries and that of the left received his of the common iliac ipsilateral, abdominal aorta and one of the arteries right renal. The fourth case, is a right iliac kidney receiving its vascularization of the aorta by two arteries and contralateral common iliac by a branch. Message to remember: The arterial vasculature of the ectopic kidney originates at the level at which the migration stopped. Given the variability in the number, origin, route and termination of ectopic kidney arteries, it is important to know them for the adequate management of renal vascular diseases, especially the renal artery interventional and follow-up. renal transplantation.
