K.S.
My mother had this done last year. She had a bad experience where she had to catheterize herself for weeks afterwards. And she occassionally still does when she gets a bladder infection, which is regularly.
My chiropractor said if she had gone to see him, he thinks he could have helped her with it. She was seeing him for a short time anyway, but stopped when her insurance stopped. I would recommend finding a good chiropractor - one you're comfortable with and one who will work with you on payment if your insurance doesn't cover it - and trying that first. It certainly can't hurt!
