Hi,
Hematuria or blood in the urine can be due to many conditions. such as trauma, stones, infections, viral infections, nonspecific inflammations of the kidney or obstructions of the urinary tract. The evaluation of hematuria requires that examining the entire urinary tract including the kidneys, ureters, bladder, and urethra. Management of blood in urine depends upon the underlying cause. It is good that your cytoscopy showed normal results.
