Bladder infection(s)

OVer the past few years I have had many bladder infections.
BPH was getting worse and finally about 1.5years ago had
a successful PVP. Flow is great, make it through the nites
without waking, everything seems to work just fine.
But....every few months I still end up with a bladder
infection, the doc puts me on antibiotics, it goes away
and then the whole scenario starts over again ! Neither
my Doc or URO can seem to come up with a cause. Last visit
another infection, heavy duty antibiotics and here we go
again. Was told I might have to go on low dose anti's.
Really don't like that option, eventually I would think the
drugs would no longer be effective and if something else major
occured, would be in real trouble.
Anyone out there had similar experiences ? Am looking for
anything that might have been overlooked.
Am 67 and in otherwise good health.
Sorry for the long post, TIA for any help.
