Because my bladder does no communicate with my brain I have no way to empty it apart from inserting a plastic pipe every 4~5 hrs and draining the contents out.
Pushing a foreign body into a normally sterile environment is a sure way to introduce infection however careful I am. So I was always dealing with Urinary tract infections and as the muscle structure of my bladder through lack of use over the years is flabby and very folded/creased it harbours pathogenic bacteria mainly e coli.
Antimicrobial Peptides, Innate Immunity, and the Normally Sterile Urinary Tract
this paper put me on to raising vitamin D status This is probably the best way to top up your vitamin D tank
Country Life, Vitamin D3, 5,000 IU is the form I use as it uses MCT medium chain triglyceride oil as the carrier, This is most easily metabolised, has a long shelf life so less likely to become oxidized, and doesn't add to your omega 6 burden.
Doing that reduced UTI's considerably and I was able to stop the low dose daily anti biotic however I did continue to get regular repeat UTI's.
I've (touch wood) stopped those by using Curcumin
as well as the Vitamin D daily.

It's also important to build up the GOOD bacteria in your digestive system as they out compete the pathogenic flora.
Bifidobacteria beat up Escherichia coli
so eating live yoghurt or other good source of bifidobacteria is a good idea. These bacteria prefer a low inflammatory environment so consuming a low inflammatory diet, low sugar/fructose, no omega 6 industrial seed/grain oils like corn/soy/safflower/sunflower/cottonseed or any foods that contain them, will reduce bacterial infection.
Also it's worth bearing in mind that oral infection, plaque growing on teeth, can be the source of lots of different infection. These bacteria flourish in a high carbohydrate environment. So eating less often and using Xylitol in between will reduce oral infections.
I use a xylitol toothpaste (flouride free) and powdered xylitol both from IHERB code WAB666 $5 introductory discount. Iherb offer cheapest shipping to UK other suppliers may be cheaper for the same products depending on delivery charges.
Drinking green tea (brewed at home using green tea leaves water off boil, 2 minutes only brew time) also has anti microbial properties that works against pathogenic gut flora like e coli.
I think you need to attack UTI infections from all angles at the same time. I don't think you should put all your eggs in one basket. Vitamin d and curcumin work together, green tea adds to their impacts and xylitiol adds an further level of protection as do the diet changes.
