43- yr old female. recurrent uti's. usually after marital sex (despite voiding and cleaning afterward). is cystoscope really necessary? options?

Cystoscopy: Can be helpful in understanding recurring vs incompletely treated cystitis. Largely depends on how far apart your infections were and how well documented they were with cultures. Also, not everything that causes red or white blood cells in the urine is infectious. I would encourage you to have the cysto, especially if its a flex cysto in the office with local anesthetic. It's brief and simple.
