Hi Steph,
The neo Bladder as you know is made out of 24 inches of your small intestine. the problem with using the intestine as a bladder is that the intestine produces a "mucus" and it can clog you up if you don't drink enough fluids they leave the catherer in for 3-4 weeks for two reasons one to allow time to heal and also to allow you to irrigate the mucus that the neo bladder will produce. Three or four times a day, sometimes more you will fill a large syrgine like device with sodium chloride irrigation solution to flush the catherer. You put the solution in and draw it back out until the solution is clear (no mucus in the syrgine). After about a year the neo bladder will stop producing this mucus. It looks just like egg drop soup, something we will never eat again.
