Just a word of caution, Anne. When a doctor says that he doesn’t recommend or do a particular procedure, I wouldn’t chose him to do one. From past experience (not with a bladder issue) I have found that when things do not work out the response is “I told you so” rather than work toward a solution. If an Indiana is desired, your mother needs to find someone who is 100% invested in the success of that diversion.
And, by the way, what IS your mother’s preference? She is the one who will be living with/dealing with the result and it is a very personal issue.
