One of the follow-up solutions to a cystectomy is the creation of a neobladder (one form of which is named Studer's Ileal Neobladder or the Studer Pouch). A neobladder is a loop of intestine that is surgically fashioned into a pouch and placed in the location of the original bladder. It is then attached to the ureters and the urethra , thus simulating the function of the original organ. The kidneys filter the urine into the neobladder which can often be emptied by muscle control. There are side effects of this complex surgery, including partial shut down of the digestive system (in response to removal of the piece of intestine), incontinence , and the loss of the nerves that signal a full bladder.
