Mild hydronephrosis was detected in 103 kidneys during routine prenatal ultrasound. After birth, 71 affected neonates were prospectively followed for 36 months. When kidney volumes were normal at birth, a normalizing trend characterized their evolution: within 6 months, 51% and within 3 years, 80% of the cases of hydronephrosis underwent spontaneous resolution. All cases of mild hydronephrosis could be caused by ureteropelvic junction immaturity. Sixty-seven percent of kidneys with volume greater than normal at birth, needed surgery.
