RENAL ABNORMALITIES IN CHILDREN WITH HYPERTROPHIC PYLORIC-STENOSIS - FACT OR FALLACY

Retrospective review of the abdominal ultrasound (US) examination of 2 74 children studied for hypertrophic pyloric stenosis (HPS) was undert aken to determine if there is an increased incidence of renal disease as previously reported. Five major abnormalities were detected in the 126 children with HPS. Three lesions were newly diagnosed and two had been diagnosed previously. Five children had abnormalities classified as minor or normal variants. Renal abnormalities were found in six of the 148 children who did not HPS. Only three of these were newly diagn osed and medically important. Eight children without HPS had minor abn ormalities or normal variants of the kidneys. Newly diagnosed medicall y important renal lesions were present in 2.4% of children screened fo r HPS. The incidence of the finding was the similar in children with a nd without HPS.
