A ureterostomy is the creation of a stoma (a new, artificial outlet) for a ureter or kidney. The procedure is performed to divert the flow of urine away from the bladder when the bladder is not functioning or has been removed. Indications may include: bladder cancer, spinal cord injury, malfunction of the bladder, and birth defects such as spina bifida ==Types== There are two basic types of urostomies. The first features the creation of a passage called an "ileal conduit." In this procedure, the ureters are detached from the bladder and joined to a short length of the small intestine (ileum). The other type of urostomy is cutaneous ureterostomy. With this technique, the surgeon detaches the ureters from the bladder and brings one or both to the surface of the abdomen. The hole created in the abdomen is called a stoma, a reddish, moist abdominal protrusion. The ileal conduit is not painful; it has no sensation. The ureterostomy stoma retains sensation. Since it has no muscles to regulate urination, urine collects in a bag. There are four common types of ureterostomies: *Single ureterostomy. This procedure brings only one ureter to the surface of the abdomen. *Bilateral ureterostomy. This procedure brings the two ureters to the surface of the abdomen, one on each side. *Double-barrel ureterostomy. In this approach, both ureters are brought to the same side of the abdominal surface. *Transuretero-ureterostomy (TUU). This procedure brings both ureters to the same side of the abdomen, through the same stoma. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ureterostomy」の詳細全文を読む スポンサード リンク
