title: [Ureteropelvic junction syndromes: antenatal diagnosis].
abstract: Seventy-four hydronephrosis by uretero-pelvic obstruction, discovered by antenatal real-time ultrasound, have been managed on sixty-one children. Three groups, with a specific management, are distinguished. The minimal forms have been only watched over (15 cases). The average forms have been operated (49 cases); considering the results (3 immediate complications and 2 early stenoses), it seems better to wait for 4 months to operate and to place a drain in renal cavities. In major forms (silent kidney on IVP), the diagnosis and therapeutic management use the percutaneous nephrostomy (10 cases). The interest of antenatal diagnosis of uretero-pelvic obstructions is to allow to operate, not only before the renal deterioration emphasizes, but principally before septic complications.
