Urinary continence with a Kock or Mainz pouch is achieved by a nipple valve of the invaginated ileum which is usually fixed with metal staples. However, metal staples can cause various complications as a foreign body. The seromuscular stripping method, a new technique to create a nipple valve, was applied to 17 patients with bladder cancer in the construction of a continent urinary reservoir by the ileocolonic pouch (Mainz pouch). Metal staples were not used. The results were satisfactory except for 2 patients who became incontinent because of prolapse of the nipple in one and insufficient valve function due to ischemic change of the nipple valve in the other. Histology of the nipple valve from an autopsy case showed a good double layer nipple valve that functioned well to preserve continence.
使用科克（Kock）或美因茨（Mainz）贮尿囊实现尿控是通过内翻回肠的乳头瓣来完成的，该乳头瓣通常用金属吻合钉固定。然而，金属吻合钉作为异物可引起各种并发症。浆肌层剥离法是一种制造乳头瓣的新技术，在17例膀胱癌患者采用回结肠贮尿囊（美因茨贮尿囊）构建可控性尿液贮器时应用了该技术。未使用金属吻合钉。除2例患者外结果均令人满意，其中1例因乳头脱垂导致尿失禁，另1例因乳头瓣缺血性改变导致瓣膜功能不全而出现尿失禁。1例尸检病例的乳头瓣组织学检查显示为良好的双层乳头瓣，其功能良好，能有效保持尿控。
