Abstract
OBJECTIVES: The purpose of this study was to determine the prenatal diagnostic accuracy of 2-dimensional ultrasonography (2DUS) alone versus 2DUS in combination with 3-dimensional ultrasonography (3DUS) for penoscrotal transposition. METHODS: Fetuses suspected of having penoscrotal transposition on the basis of ultrasonographic findings or a family history were examined by 2DUS and then 3DUS. RESULTS: Of a total of 22 fetuses, 14 had penoscrotal transposition at birth. The combination of 2DUS and 3DUS correctly identified more of the penoscrotal transposition cases than 2DUS alone (90.9% versus 63.6%; P < .05). CONCLUSIONS: The combination of 2DUS and 3DUS improved the prenatal detection rate for penoscrotal transposition compared with 2DUS alone.
