urachal diverticulum

urachal diverticulum

a usually asymptomatic type of vesical diverticulum resulting from a urachus that has closed at the umbilical end but not at the bladder end. It is seen most often in children, those with prune-belly syndrome, and persons with a bladder outlet obstruction.

urachal

pertaining to urachus.

urachal abscess
a mass palpable in the abdomen dorsal to the umbilicus to which it is usually connected by a fistula that drips pus continually.
urachal cyst
symptomless fluid-filled cavities in the urachal ligament.
urachal diverticulum
visible with contrast radiography as an extension of the bladder at the vertex. See also vesicourachal diverticulum.
urachal inflammation
usually results from an extensive infection of the umbilicus. The urachus may or may not be pervious. Cystitis or urachal abscess may follow.
persistent urachal ligament
maintains tension on the bladder leading to incomplete filling and emptying. The elongated bladder with a pointed vertex is readily visible radiologically.

Urachal anomalies may be present in 2% of general population and they are classified into four anatomical categories-patent urachus-50%, urachal diverticulum -3 to 5%, umbilical urachal sinus-15%, and urachal cyst--30%.
Persistence of the urachus may be partial giving rise to urachal cysts, urachal diverticulum or sinus, or may be complete allowing communication with the bladder.
Incomplete closure of this embryological communication may result in a urachal fistula, urachal sinus, urachal cyst or urachal diverticulum (Fig.
