[Diagnostic and surgical errors in congenital hydronephrosis in children].

34 children with congenital hydronephrosis, operated upon for erroneosly diagnosed acute appendicitis (17), malignant tumor (11), and ileus (8), were under observation. To prevent from unwarranted surgical interventions in dubious cases excretory urography and other x-ray and instrumental methods of examination must be used widely. After the removal of an unchanged vermiform process in children, suffering from abdominal pain, the examination of the urinary tract is indicated. Such patients should be under dispensary observation of a children's surgeon.
