Megaureter associated with severe renal dysplasia

The diagnosis of megaureter can usually be made quite easily with ultrasonography. A large anechoic tubular structure can be seen with communication to the kidney and/or bladder demonstrated. We present a case in which massive megaureter was found in association with severe renal dysplasia. Inability to demonstrate a connection of the megaureter to the rest of the urinary system caused difficulties in accurate radiologic diagnosis.
