Hi red,
I had severe cervical and lurabar stenosis and had surgery for both in April and May this year (neck,which was much more serious, first). I have bladder problems, but not as severe as full incontinece. I was told, after urodynamic testing post-operatively, that my bladder issues stem from my cervical stenosis, not my lurabar, but I think it can be caused by either, depending on where the stenosis is impinging nerves.
I would definitely contact your neurosurgeon to move your surgery date up and also contact a urologist (urogynecologist if you are female). Even if surgery does not improve your bladder situation, there are other things than may be able to improve it, depending on your situation. I have also been told, like marcia, that when you have something severe (like full incontinence) show up, you need to be taken care of promptly so as to increase the chances of avoiding permanent damage. Don't be afraid to be the 'squeaky wheel' here and get that surgery moved up. And, don't forget that your bladder problems may have another way of being resolved or at least aided, if surgery does not help.
As for your electric wheelchair. I wasn't as 24/7 with my walking problems, but I was using a seated walker before my surgeries. I could walk very short distances on my own, but pushed my walker or used a cane for that. I would use my walker as a wheelchair when I couldn't walk anymore (hubby pushed me in it). I do not need it anymore, although I use my son's wheelchair if I am going to be out for a long outing (my son doesn't need it all the time, same as me). I have used a wheelchair only twice since my back surgery in May, once for a 6hour day at the state fair where I would walk a long stretch, then sit and rest in the chair -and once for a friend's son's bar mitzvah (to have softer seating and my legs extended since the seating provided was not going to be something I could manage longer than 15 minutes or so).
I didn't get 'the old me' back after my surgeries, but I am MUCH improved from where I was and I was 'saved' from further problems I was heading toward. I have very much benefitted from both surgeries and am muuuuch more mobile than I was (and believe I'll continue to improve with this even more as I move further into 'long-term' recovery).
I wish you only the very best outcomes possible! Take care.
