The urachus, derived partly from the allantoic canal, tethers the apex of the bladder to the umbilical ring. This vestigial structure, though constant in man, is formed by a whole series of embryologic mechanisms which are still controversial. Total or partial persistence of the lumen of the urachal canal, when sufficiently extensive, becomes manifested by characteristic clinical features. Moreover, it is frequently associated with malformational urogenital involvement, which must be routinely sought. The sole form of treatment consists of total surgical excision of the urachus.
脐尿管部分源自尿囊管，将膀胱顶部与脐环相连。这个退化结构在人类中虽恒定存在，但其形成涉及一系列胚胎学机制，目前仍存在争议。脐尿管腔完全或部分持续存在，当范围足够广泛时，会表现出特征性临床症状。此外，它常与泌尿生殖系统畸形相关，必须常规排查。唯一的治疗方式是对脐尿管进行完全手术切除。
