A toilet seat bidet called Swash 300 made by Brondell , the S300 model can replace a regular toilet seat and helps to keep rectal area clean. Miralax as laxitive is very helpful.
Urologist recommended D-Mannose 1000 mg twice daily to help prevent recurrent UTI.
He said 90% UTI caused by E.Coli and that mannose works by preventing the bacteria from sticking to the bladder wall. I hope you don't ever have these problems but IF you do these are things I have found useful.
