title: [Treatment of hydronephrosis caused by obstruction of the pyeloureteral junction diagnosed before birth].
abstract: From 1981 to 1987, the authors observed 69 patients with ureteropelvic junction obstruction diagnosed by antenatal ultrasound, representing a total of 77 pathological renal units. Seventy renal units were treated by ureteropelvic resection, one renal unit returned to normal without treatment. There were 3 primary nephrectomies and 3 secondary nephrectomies for non-improvement after percutaneous nephrostomy. An early antenatal surgical management of ureteropelvic obstruction after antenatal ultrasound diagnosis does not seem to give better results than when diagnosis is made at a later stage. The interest of the antenatal diagnosis is not as important as for other uropathies such as urecterocele, mega-ureter or posterior urethral valves.
