Case report

A  16-year-old patient, G2P1, was referred to our unit at 28 weeks due to fetal bladder dilatation and bilateral pyelectasis seen at 24 weeks. Our ultrasonographic examination found:

  • Dilated urinary bladder with normal thickness of its wall;
  • Marked bilateral pyelectasia with bilateral ureteral dilatation (a renal cortico-medullar differentiation was not distinguishable);
  • Megaurethra with intraluminal dilatation;
  • Atrioventricular septal defect;
  • Polyhydramnios;
  • Fetal stomach was not observed.

An amniocentesis was done and revealed normal karyotype (46, XY). The parents opted for the continuation of the pregnancy, but they move back to their home island and lost from our follow up monitoring, but the findings could fit to the VACTERL (VATER) association.
