title: Surgery of megaureters--modification of Hendren's operation.
abstract: It was Hendren's contribution to introduce an aggressive restorative procedure for the entire urinary tract in children with the megaureter syndrome. Our own experience in applying this method enabled us to more critically assess its value and prompted us to introduce some modifications. Instead of longitudinally resecting the dilated ureter we applied a method in which the dilated ureter wall is folded. This prevents injury to the ureter wall and its necrosis. We have given up excessive shortening of the elongated ureter, since the elongation proved to be spurious. We have also given up reconstruction of the upper part of the ureter.
