Prenatal sonographic diagnosis of ureteroceles usually involves clearly duplicated
urinary collecting systems associated with ectopic ureters draining the upper renal
moieties. We present an unusual case in which an initial sonographic examination was
consistent with bilateral orthotopic ureteroceles in association with bilateral single
renal systems. The possibility of single systems raised perinatal considerations unique
to this anomaly. Repeat prenatal sonography was suggestive of duplex systems and subsequently
confirmed as such by neonatal ultrasound and voiding cystourethrogram. At the age
of 1 month, the infant underwent bilateral ipsilateral ureteroureterostomy with conservation
of the bilateral dilated upper renal moieties. We discuss the possible pathophysiology
underlying the different conflicting sonographic findings and address current management
of such lesions.
