title: The diagnosis of yo-yo reflux with dynamic renal scintigraphy in a patient with incomplete ureteral duplication.
abstract: The diagnosis of yo-yo reflux in patients with incomplete upper collecting system duplications is difficult. We report a case with recurrent urinary tract infections and ultrasonographically detected duplication in the left collecting system in which the presence of yo-yo reflux is demonstrated with dynamic renal scintigraphy.
