Thank you for checking up. I am not good at navigating sites such as this but I do receive email notices from this site that I go into, i.e. this post from you. Since Good Friday my urine has returned to normal....normal color, very little bubbles in urine only periodically, and no pain in side or back. On March 29 my urologist did agree to give me a prophylactic nitrofurantoin mono 100 mg prescription to take nightly to keep infection at bay although he said it was not infection because it did not culture. I still believe this was infection. I am going to give it another week then stop nitro.mono and see what happens. He wants to do a repeat cystoscope May 11 and has ordered a CT urogram (waiting to hear from hospital for schedule) even though CT scan (without contrast) and subsequent ultra sound showed nothing abnormal, as did his first cystoscopy. I am debating whether to undergo all this extra testing if urine continues to be "normal". I have no symptoms of bladder cancer, etc.
