Abstract:

Objective: To evaluate the perinatal consequence after fetal pelvic-amniotic shunt for bilateral antenatal hydronephrosis. Methods: A retrospective analysis of 35 fetuses with bilateral hydronephrosis was made in the Obstetrics Department of Henan Provincial People′s Hospital from January 2017 to October 2020 through multidisciplinary consultation. 7 cases in the intrauterine treatment group were given pelvic-amniotic shunt on the severe side of hydronephrosis, and 28 cases who had regular reexamination of the degree of hydronephrosis were conservative group, to analyze the relief of hydronephrosis and amniotic fluid volume after shunting, and the perinatal outcome, neonatal survival rate and operation rate of the two groups were compared. Results: Fetal hydronephrosis was relieved after shunt in 4 cases, accounting for 57.14% (4/7), and amniotic fluid volume improved in 6 cases, accounting for 85.71% (6/7). The compression of hydronephrosis on the fetal kidney parenchyma had remitted in different degrees after vesicoamniotic shunting, the 28-day survival rate of newborns and the operation rate in the intrauterine treatment group were significantly higher than that of the conservative group(P<0.05). There was no significant difference in the half-year survival rate and 1-year survival rate of the two groups(P>0.05). Conclusions: Pelvic-amniotic shunt can reduce the compression of hydronephrosis on the fetal kidney parenchyma, improve amniotic fluid volume, and can improve the 28-day survival rate of newborns.
