[Results of pyeloplasty in children (author's transl)].

The results of 47 surgically corrected cases of stenosis of the pyelo-ureteral junction in children are presented. The method of Anderson-Hynes is preferred because of the removal of the functionally and morphologically damaged ureter-segment. In 80% of the cases the postoperative x-ray demonstrated a good result. Some of the other patients required a secondary nephrectomy. In 10 patients the technique of Culp-de Weerd was used. Six patients showed good results. Postoperatively the urine was sterile in 2/3 of the examined children. In some of the patients the postoperative follow-up was insufficient Etiology. Diagnostic procedure and indication for surgery are discussed.
