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.
