The authors retrospectively analysed the ultrasonographic findings of 43 cases of surgically confirmed hypertrophic pyloric stenosis and their postoperative findings of sonograms taken at 1 month(n=40) or 3 months( n=5) after pyloromyotomy. In preoperative study, the thickened pyloric muscle was isoechoic or slight hypoechoic relative to liver on the midline longitudinal view and appeared as a "nonuniform acoustic ring" on the transverse view. The results of measurement in the all cases with hypertrophic pyloric stenosis were the pyloric thickness ≥3.8mm, the pyloric diameter ≥14mm, the pyloric channel length ≥16mm, the pyloric muscle volume ≥2.21Cm
