Clinical significance of ultrasound diagnosis in fetal mild pyelectasis

Objective：To investigate the value of prenatal ultrasound diagnosis and prognosis in fetal mild pyelectasis.Methods：Follow-up observation of 76 cases of fetal mild pyelectasis screened by prenatal ultrasound was performed.Results：Among the 76 cases,there were 41 cases of bilateral fetal mild pyelectasis,37 of 41 cases returned to normal after the birth and 3 cases didn＇t,including 3 cases with chromosomal abnormalities and 1 case with urethral malformations.There were 35 cases of unilateral fetal mild pyelectasis,34 cases from them returned to normal after the birth;the pyelectasis remained unchanged in one case and skeletal malformation was found.Of the 52 cases of 20~33 weeks of pregnancy with fetal mild pyelectasis,48 cases returned to normal after the birth and 4 cases didn＇t.Of the 24 cases of 33 weeks of pregnancy with fetal mild pyelectasis,23 cases recovered after the birth and 1 case didn＇t.Conclusions：Prenatal ultrasound can detect fetal mild pyelectasis and a variety of malformations sensitively and can provide references for clinical treatment and genetic counseling.
