I have had uti's for 3 years. 2 years ago I had a bladder sling inserted by urogolist that told me that would cure my problem. 2 years later I'm still have uti's, I'm always on antiobiotics, every culture comes back negative & know my new urogolist says I have a enlarged bladder which he says first uro should have caught that when I had the urodymantic test. Now he wants me to cath but with my constant uti's I don't think that is a good idea. I have been on Bactrim, Cipro, Macrobid & augmentin. My last ua showed blood, protein & white cells I don't know what to do could you please give me some advice. Also sex is not an option since the sling was inserted. Please help me.
