Collagen Bulking agents as a help with incontinence.

Body: 

After having biofeedback treatments, neuromodulation treatments, insertion of a trans-obturator sling to support my urethra, and watching diet closely, doing my Kegels daily, I still have incontinence. Now, I am wondering about the help of a bladder sphincter bulking agent to lessen the urinary leakage. Does anyone have suggestions? Thanks you. Sally

why the incontinence, that is.
I can only assume that *if* the problem is an underdeveloped sphincter, if there is such a thing, than maybe a bulking agent would prove useful. in my (uneducated) mind, you'd want to be sure not to overbulk it or you'd end up unable to void.
my ds is having bladder incontinence troubles and we're going down the diagnosis road. I know a 7 yo boy is way different than a woman with a prolapse, but I think that the principle of proper diagnosis before shot-in-the-dark treatment is a good idea either way.
with my ds, everything's been ruled out thus far, aside from a 'tight internal sphincter' which they can't assess without very invasive techniqe. the recommendation now is an alpha-blocker to relax the sphincter. thought is, that after working so hard to get the urine past a tight sphincter, the bladder has lost its tone and is no longer responding normally to the neural feedback systems. I wonder if a similar thing happens with a prolapse. the bladder tips and has to work harder to void and then 'forgets' how to function properly.
just a thought, probably useless, but interesting to me nonetheless.
