text: why does my urine smell so bad? everytime i go to the bathroom, it's embarrasing to me because my urine smells really bad. i have pielonefritis 3 years ago and now i think i am ok but it's already been like 2 years like this and i would like to know what it is and what to do, i've tried everything... even odorizer for my friends bathrooms when i am visiting. here is an answer in espanol since you used the spanish word for the kind of kidney infection you had.  http://www.umm.edu/esp_ency/article/000522.htm  see especially olor de la orina. i hope this helps. the pages can be read in either english or spanish. select the one that is most comfortable at the top of the page.
