Umbilical urachal sinus

Umbilical-urachal sinus is a congenital disorder of the urinary bladder caused by failure of obliteration of proximal or distal part of the allantois, and the presentation of this anomaly is more common in children and rarer in adults. In contrast to a urachal diverticulum (patent urachus), it is characterised by focal dilatation of the umbilical portion of the remnant urachal tract.

It is thought have been first described by Cabriolus in 1550.

Complications

Infection, with possible abscess formation.
Concurrent occurrence of a tumour.
