Hello. I have systemic lupus (calm). I usually get lab work done 1-2 times a yr. to check my kidney, etc. due to the lupus.  Three yrs. ago, June 2010 Ive been having occult blood (1) in my urine. I asked my Rheumatalogist and she said I probably took the urine test close to my period or near the end of my period and thats why it showed the occult blood, so I didnt worry anymore. This July I had my lab work done and again the occult blood (1) showed up (as it has been in the last 3 yrs.). This time however my Rheumatologist was concerned and told me to see a urologist. Because I couldnt see a urologist sooner, I went to see my family doctor. He ordered a urine test and an ultra sound of the kidney. He diagnosed me as microhematuria. When I finally saw the urologist, she ordered a urine cytology and recd that I get a cystoscopy esp. because my lab showed  occult blood (1) along with rbc 4-10 . She wanted to make sure that I dont have a bladder cancer or kidney disease so a cystoscopy needed to be done. When I did the urine test that day, I believe the cup was contaminated thats why it showed the rbc 4-10. When repeated, it didnt show rbc 4-10, but normal  rbc 0-2 (below)Results
Hi there, she can affect kidney the best way to detect is RBC in urine examination> 4, urine spot protein creatinine ratio > 0.2 and high DSNA and low c3 levels. Then we call it lupus nephritis.  In your case stone is also present. So RBC can be because of stone also. It is important to rule out SHE nephritis as it is more dangerous. X-ray may not be helpful.  If you wantvimaging study to document stone size and number than ct pub plain should be done. It has no effect on future pregnancy.  If the stone is a single stone of 3 to 5 mm as in the ultrasound.  There is no need of anyvtreatment before pregnancy.  If a problem arises it can be tackled as such chances are very less as it is a very small stone. Chancellor cancer are only there if your age is greater than 50 yrs in that case also ct should be done before cystoscopy. And most likely cystoscopy will not be needed. Best wishes.
