title: Robotic correction of Östling folds as a rare cause of ureteropelvic junction obstruction in children.
abstract: Östling folds are considered to be normal variants of ureteral growth at a quicker rate than body lengthening and, therefore, have been reported to be of no clinical significance. We report a robotic correction of the first documented cases of Östling folds causing a persistent ureteroplevic junction obstruction in children.
