The surgeon will take a segment of large intestine and a small portion of the ileum to make an internal pouch into which the ureters flow. The short piece of small intestine is brought to the surface of the abdomen (the stoma). There is no external pouch and the stoma is very small, and can be covered with a bandage. A catheter inserted into the stoma is used several times per day to empty the pouch.
Advantages: No external pouch, no odours, no body image issues.
Disadvantages: Longer surgery time, the need for catheterization, possible risk of leakage from the stoma, scarring of the stoma making catherization difficult, stones in the pouch.
