title: Crossed renal ectopia with colic. A clinical clue to embryogenesis.
abstract: A clinicopathologic correlation of 2 patients with crossed renal ectopia presenting with ureteric colic and 4 cases collected from the literature is presented. The correlation serves to reaffirm the theory of ureteral and not renal, migration as the primary aberration resulting in this defect.
