One end of the intestinal segment is sealed off. Both ends of the ureter are now implanted into this intestinal segment so that the urine ends up here. The other end of the intestinal segment is drawn through a gap in the abdominal wall and sutured to the skin.
The patient then has a stoma, which is covered by an ostomy bag. It is easy to manage. It cannot be seen under clothing and is odourless. Because the urine does not remain in contact with the intestinal mucosa, the re-uptake of urinary metabolites is minimal.
