A urachus is a vestigial tubular structure that connects the urinary bladder to the allantois during early embryonic development. Urachal remnants are classified as patent urachus, urachal sinus, urachal cyst, and urachal diverticulum. Ten patients with urachal remnants underwent surgery at our institution between 2015 and 2019. Six patients had a urachal sinus, and four had a urachal diverticulum. Two patients with urachal sinus underwent excision of the urachal remnant, from the umbilicus to the urinary bladder, using an umbilical approach. The other four patients with urachal sinus underwent laparoscopic surgery with excision of the urachal remnant, from the umbilicus to the urinary bladder. All patients with urachal diverticulum underwent open excision of the diverticulum through a Pfannenstiel incision. Pathologic examination of all urachal remnants showed no evidence of neoplasm and complete excision. All patients had an uneventful postoperative course and are doing well.
脐尿管是一种退化的管状结构，在胚胎发育早期将膀胱与尿囊相连。脐尿管残余物分为开放性脐尿管、脐尿管窦、脐尿管囊肿和脐尿管憩室。2015年至2019年间，有10例脐尿管残余物患者在我院接受了手术。6例为脐尿管窦，4例为脐尿管憩室。2例脐尿管窦患者采用脐部入路，从脐部至膀胱切除脐尿管残余物。另外4例脐尿管窦患者接受了腹腔镜手术，从脐部至膀胱切除脐尿管残余物。所有脐尿管憩室患者均通过Pfannenstiel切口进行憩室开放切除。所有脐尿管残余物的病理检查均未发现肿瘤迹象且切除完整。所有患者术后过程顺利，恢复良好。
