dear user about your question i would like to tell you that symptoms of urinary tract infection differ from person to person ...it can be burning sensation...and polyuria which means peeing alot.....itching and mild fever and discharge... urinary tract infection may be due to fungal or viral or bacterial infection.... you had arisk factor to get urinary tract infection as you mentioned you did TURBT plus Ureteroscopy you can take it simply and follow these steps to get worry out....... you need to do urine culture as primary investigative test of bacterial infection as in this case you should have antibiotics for treatment ...althaugh you took azithromycin but it may have no effect as there is bacteria may resist it and urine culture and antibiotic sensitivity test will detect simply the way of treatment and selection of the approbriate antibiotic that will give best results with bacteria detected........discuss with your doctor to do urine culture and antibiotic sensitivity test as it will help alot.......you should drink alot of fluids and avoid any sexual contact till investigations comleted........wish you healthy life
