RT Journal Article SR Electronic T1 Bilateral additional renal arteries and an additional right renal vein associated with unrotated kidneys JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 535 OP 537 VO 24 IS 5 A1 Alp Bayramoglu A1 Deniz Demiryurek A1 Kadriye M. Erbil YR 2003 UL http://smj.org.sa/content/24/5/535.abstract AB We report a rare anomaly of the kidneys and its vessels, which were found during the routine dissection of a 68-year-old male cadaver. The anomaly consisted of bilateral additional renal arteries originating from the abdominal aorta and an additional right renal vein accompanying the additional right renal artery. These anomalies were associated with unrotated kidneys with extrarenal calices and pelves. All the additional vessels were located posterior to the ureter with a close relationship to the ureteropelvic junction on the right side. Additional renal vessels arise as a result of the complicated development of kidneys and variations in the positional anatomy of the kidneys, and their vascular supply are of clinical importance.
