I am 44 female with SLE. For the past 6 months or so I have been having black specks in my urine off and on. Sometimes there are several black specks, sometimes just one, and sometimes none. My urine has a strong smell which my daughter can come into the bathroom after I have gone and complain of the smell. Over this period of time, every time I have had a check up with my doctor there has been blood found in my urine sample. The first time I was treated with antibiotics, but nothing has been done since. I was given a screen to catch these tiny black specks and got 2 of them (one larger than the other) and took them back for observation in the lab. These came back as unable to identify . Since then, my doctor has been assuming these specks are kidney stones. I have no pain when they pass through my urine, and most times I wouldn t even know if I have not gotten into the habit of looking in the toilet every time I pee now. I used to smoke but have quit for 18 weeks.
