Abstract
We report a case of metastatic urachal cancer where the immunohistochemical profile's similarities to colon cancer led to treatment with colon cancer specific chemotherapy. Our case is the first to report urachal cancer treated with and responding to modified FOLFOX6. In the age of targeted therapy,...

Abstract
Pathologic stage is an important prognostic factor in urachal carcinoma. Surface urothelial involvement by carcinoma and presence of cystitis cystica/glandularis do not necessarily exclude the diagnosis of urachal carcinoma. Immunostains do not unequivocally discriminate a urachal from a colorectal...

Abstract
Burch's procedure in addition to urachus-cystopexy was better for the treatment of SUI and UUI than Burch's procedure alone in a long term clinical follow-up. Surgical fixation of the urachus to the anterior abdominal wall provides extra support to the bladder and probably reduces its displacement d...

Abstract
A small urachal remnant, especially at birth, may be viewed as physiological. Urachal remnants in patients younger than 6 months are likely to resolve with nonoperative management. However, if symptoms persist or the urachal remnant fails to resolve after 6 months of age, it should be excised to pre...

Prenatally, the umbilicus is of paramount importance, providing the gateway between the mother and the fetus. As the fetus becomes increasingly autonomous at the end of the second month of fetal life, the connections (vitelline, urachal) diminish in significance and involute. Disturbances in this pr...
