Hi Debbie,
The procedure you had is called a Cystoscopy. I have also had this done a few years ago and everything came back normal.
There have been many times through the years where more than one antibiotic has to be tried before the UTI is gone. I just finished a second antibiotic recently for another asymptomatic UTI.
This explains a Cystoscopy, the reason for having one and what it can show:
