My MS clinic makes UTI screening mandatory whenever a relapse is suspected. Even if we swear up and down that we don't have a UTI. They also make sure the urine gets sent for a culture each time instead of just the dipstick test. They tell me that they routinely find UTIs this way.

I just had an asymptomatic/near asymptomatic UTI that I got tested for only b/c of flare up. Second UTI in my life. I didn't catch it in time and it sent me into mild relapse.

No personal experience, but I've read that if the bladder is not fully emptying it can lead to UTIs. Apparently the solution to this is intermittent self catheterization.

I'm thinking I should actually find out of there are home UTI testing kits.
