Urachus is the remnant of the embryologic allantois and the fetal bladder, extending form the bladder roof to the umbilicus. It degenerates in the prenatal period into a tissue band known as the median umbilical ligament. Incomplete degeneration may lead to urachal diverticle development. It is difficult to diagnose unless it is considered in differential diagnosis and imaging modalities are employed. This paper describes a patient treated with partial cystectomy for urachal diverticle, and the pathologic examination revealed urachal adenocarcinoma.
脐尿管是胚胎尿囊和胎儿膀胱的残余部分,从膀胱顶部延伸至脐部。它在产前阶段退化为一条称为脐正中韧带的组织带。退化不完全可能导致脐尿管憩室形成。除非在鉴别诊断中考虑到并采用影像学检查方法,否则很难诊断。本文描述了一名因脐尿管憩室接受部分膀胱切除术治疗的患者,病理检查显示为脐尿管腺癌。
