title: Bilateral duplex ectopic ureters terminating in the seminal vesicles: sonographic and CT diagnosis.
abstract: A 15-year-old boy presented with a short history of right-sided flank pain was found to have bilateral duplex renal systems with obstructed upper poles. Sonographic examination and contrast-enhanced delayed computed tomography (CT) performed at the conclusion of the excretory urography (EU) demonstrated termination of both obstructed ureters in the seminal vesicles. These noninvasive studies allowed accurate preoperative diagnosis of this abnormality.
