[Results of follow-up studies in children with megaureters]

It is reported on the results of after-examinations in children with megaureters. The average interval between first operation and last after-examination is 8.1 years (1 to 14 years). Of altogether 63 children ten died, eight of their disease, including the postoperative complications. Eleven children were nephroureterectomized. In spite of the time of satisfying results concerning the renal function the prognosis is uncertain, particularly of the children with bilateral malformation. The number of the infections of the urinary tract is large and the deterioration of the function due to pyelonephritis is not to be foreseen. Changes or modifications of the operation technique and a strict dispensary care of the children let us hope for an improvement of the results during the next years.
