Neonatal urinary ascites complicated by ileal perforation in a recipient of twin-to-twin transfusion syndrome.

We present a case of iatrogenic neonatal urinary ascites following antenatal amnioreduction in one of the monochorionic diamniotic recipient twin 2 of twin-to-twin transfusion syndrome (TTTS). He had ileal perforation following postnatal abdominal paracentesis. The patient had an uneventful recovery following exploratory laparotomy, resection of perforated segment of ileum with end-to-end anastomosis and open vesicostomy with subsequent closure of the vesicostomy.
