title: Urologic Considerations in the Separation of Thoracoomphalopagus Conjoined Twins.
abstract: Conjoined twins are seen in approximately 1/500,000 live births, and therefore surgical management of urologic anomalies in conjoined twins has not been extensively reported. Various degrees of sharing of the urinary tracts and genitalia can be seen in different types of conjoined twins. Detailed preoperative imaging, including magnetic resonance imaging, computed tomography, and voiding cystourethrogram, is essential to define the anatomy and planning of a successful separation. We describe the urologic presentation, evaluation, and treatment of thoracoomphalopagus conjoined twins.
