### input:
I had a UA that was positive for bilirubin and leukocyte esterase. Also had red and white blood cells, epithelial cells, bacteria and mucus. Free hemoglobin was also detected.Was surgically treated for left ureterovesical reflux and periureteral diverticulum, and a right ectopic ureter.  This was in 1996 when I was 8. I had recurrent infection and scarring at the time of surgery. Since then I have had multiple U.T.I.s and kidney infections. Most UAs I take show similar~ results.I have recently found a rather large hard rounded area (lump) directly below my right ribs (3-4in size near liver/gallbladder/kidney area). It disappears under my rib cage when I lie down, and can be manually pushed up (however this feels incredibly strange) but NOT down (painful). The entire right side of my abdomen is harder than the left.Could there be another cause for the UA results?

### output:

Good Day! Leukocyte esterase, RBC, and WBC may indicate a urinary tract infection. I would suggest doing a Urine culture since it is the most accurate examination to check confirm an infection, and it also identifies the bacteria and tells us what antibiotics are appropriate to treat the infection. With the bulge on the right side of your abdomen may be a surgical hernia. You may need to see a general surgeon, so he can properly assess the lump. I am considering that there is an abnormal defect in your abdominal wall layers that causes your abdominal contents to protrude outside thereby producing a lump. Yours Truly, Chat Doctor.
