Bilious vomiting in two neonates due to an urinoma secondary to posterior urethral valves

Bilious vomiting is a common presenting sign of intestinal obstruction in the neonate. Here we report two neonates who presented with bilious vomiting due to compression of the proximal small bowel by an urinoma secondary to posterior urethral valves. Awareness of this differential diagnosis may prevent acute exploratory surgery.
