[Operative correction of primary megaureter in children (author's transl)].

Sixty-seven children with congenital megaureter were treated by surgically. Nephroureterectomy was performed in 12 cases (17.9%). Fifty-five children were selected for surgical correction. In 23 patients, a bilateral ureteroneocystostomy with submucosal tunneling was performed. These latter patients were examined in the postoperative period for the following criteria: unobstructed flow urine, improved or stable renal function and absence of infection, 69.23% of these patients met these criteria. Because the primary goal is conservation of the kidney the indication for surgical correction is quite liberal. Thirty percent were failures partially due to previous surgery. The need for detailed preoperative study and long-term follow-up is stressed.
