Abstract:
Objective To assess the clinical significance of fetal pyelectasis and its changing in utero. Methods One hundred and ninty-seven isolated pyelectasis cases were retrospective reviewed from Jan 2012 to Jul 2014.Isolated pyelectasis was defined as a renal pelvis anteroposterior diameter (RPAPD)of ≥5 mm without other fetal anomaly in second trimester.Persistent or progressive pyelectasis was defined as a RPAPD of ≥10 mm before delivery.They were divided into two groups according to the size of renal pelvis in second trimester:group A (RPAPD 5 - 10 mm)and group B (RPAPD ≥ 10 mm).As the same,there were two groups after 32 weeks of gestation:group C (RPAPD < 10 mm)and group D (RPAPD ≥ 10 mm).Results Totally 1 54 cases were followed up.There were 1 88 cases (95.4%)in group A,with 41 cases lost,141 cases (95.9%)RPAPD <10 mm,6 cases (4.1 %)RPAPD ≥10 mm before delivery.There were 9 cases (4.6%)in group B,with 2 cases lost,remained 7 cases RPAPD ≥ 10 mm before delivery. Conclusions Although most of the fetuses with RPAPD 5 - 10 mm in second trimester will remain the same or resolved before delivery,those with RPAPD ≥ 10 mm may persistent or progress.Prenatal assessment of fetal renal pelvis may provide properly consultation.
