13. A 21-year-old man is brought to the emergency department 30 minutes after being involved in an automobile collision. Findings on physical examination are within normal limits. Routine urinalysis shows a trace amount of blood. An excretory urogram shows no evidence of genitourinary injury, however, the lower poles of the kidneys are indistinct, the renal long axes are directed medially and inferiorly, and some of the calyces are oriented medially. An x-ray is shown. These findings are most consistent with which of the following? OA) Crossed ectopia with fusion OB) Crossed ectopia without fusion OC) Duplication D) Horseshoe kidney E) Simple ectopia F) Simple malrotation
