Except 58 cases missed and 5 cases induced abortion, we followed up 163 cases(241 kidneys) in different gestational age and postnatal period. Among them, 209 kidneys (86.72%) were discovered pyelectasis between 5mm to l0mm. The pyelectasis of 30 kidneys(12.45%) was between l0mm to l5mm, and that of 2 kidneys(0.83%) was thicker than 15mm. Follow-up result is as follow: 137 cases(214 kidneys) were recovered in normal in fetus period or postnatal 15 months. Their pyelectasis was thinner than 5mm(88.80%). Among them, 16 cases(2l kidneys) were recovered in fetus period(8.71%). 121 cases(193 kidneys) were recovered in postnatal 15 months(80.09%). The rest 20 kidneys' pyelectasis was between 5mm to l0mm(8.30%). 4 kidneys' pyelectatis was between 10mm to l5mm(1.66%), and 3 kidneys' pyelectasis was thicker than l5mm(1.24%).
