I feel for you. I have had chronic utis and recommend seeing a urologist to get a cystoscope (where they look into your bladder to see what's going on). I had a bunch of polyps and they stretched my urethra in the office and it helped. Also, they can do cultures and make sure they get the right antibiotics for you. This is important because obviously the problem is resistant to the antibiotics--though they work some. My docs kept giving me the same dose of the same thing over and over and it didn't work. My situation is different though. If your urine fails to culture than you may have an infection the culture wont grow or you have another type of chronic problem. Personally, I prefer a female urologist because they are more sympathetic and often specialize in our more complicated biology. Male urologists are really good with prostates, but the two I went to didn't do well at all with my situation. I ended up getting treatment at an ER at Mayo clinic when it progressed to being really really really bad.
