The distance between the distal rectal pouch and the perineum (pouch\u2010perineum distance) was measured by both sonography and prone cross\u2010table radiography. A previously established pouch\u2010perineum distance of 10\u2009mm was used as the cutoff for diagnosis of a low\u2010type imperforate anus. The fistula location was also determined with sonography. We then compared the diagnostic accuracy of the imaging methods for a low\u2010type imperforate anus using the cutoff value of the pouch\u2010perineum distance alone and both the cutoff value of the pouch\u2010perineum distance and fistula location.
