Vesicourachal diverticulum

Last revised by Dr Daniel J Bell on 10 Jan 2022

Vesicourachal diverticulum, or just urachal diverticulum, is one of the congenital urachal remnant abnormalities.

It is the proximal equivalent of a urachal umbilical sinus, representing a result of the failure of the urachus to close at the urinary bladder, forming an out-pouching of variable length from the anterosuperior aspect of the urinary bladder, which does not communicate with the umbilicus

This anomaly is identified as a urine-filled anterosuperior extension from the bladder dome on all imaging modalities. 

A urachal diverticulum frequently coexists with congenital obstruction of the lower urinary tract. Rarely a malignancy can arise within the diverticulum: see urachal carcinoma
