question: 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?
