[Specificities of the treatment of abnormal pyelo-ureteral junction in children].
Pyelo-ureteral junction abnormalities in children are most frequently discovered by prenatal ultrasound investigation. Most pyeloplasties by resection-anastomosis of the pyelo-ureteral junction are performed in young infants, usually with a posterior approach, patient prone. The indication and type of urinary pyelic drain remain debated: simple nephrostomy or double J drain. Ureteral-caliceal anastomosis is an interesting approach to rare surgical reoperations, particularly with major pyelo-ureteral dilatation. Laparoscopic surgery may prove usefulness in less small children. Endopyelotomy gives good results for post-operative stenoses.
