I have a similar problem, and a Foley catheter...

Abdominal pain, but the VA doctors don't seem to be able to isolate the cause.

However, the results of a recent scan indicate "...thickening of the bladder wall and indication of inflammation."

No mention of infection, just "inflammation."

Now for the scary part....

During another recent visit the doctor mentioned, in regard to bladder infections, that antibiotics eventually lose their affect, and infections can be fatal.

I feel certain that my abdominal pain is due to a bladder infection. I need to get a straight answer from the VA, along with what their intentions are.
