TREATMENT

A patent urachus or superior sinus should be excised using either an open or laparoscopic technique. It is essential to remove all abnormal urachal tissue because there is a small risk of later malignant transformation. Thus, in addition to the urachus, a cuff of surrounding bladder tissue should be removed as well.

An asymptomatic urachal cyst or inferior sinus can be managed with careful observation since spontaneous resolution is possible. If resolution does not occur, however, or if symptoms emerge, all urachal tissue should be carefully excised.
