Hi Steph,
I do have a catherer with my neo bladder which was made from my intestine. The catherer stays in for 2-3 weeks after surgery (it is through my penis) so that the new bladder will heal. After it is removed I will urinate just like I use to. I will have to work on controlling it and they say that can take some time. My doctor also told me prior to surgery that there were three options, the first the neo bladder, second a pouch and third an external bag. It is really look and see when they start the surgery to see what will really work the best. Any other questions feel free to ask.
Tim
