Trauma to the pelvis, a pelvis tumor, bladder or kidney stones, unwanted objects in the urinary tract or prostate hypertrophy can cause a blockage that damages the urinary system.ladder infections or inflammation of the urinary tract and ureters can also cause leukocytes to appear in the urine. Sexual intercourse can cause the transfer of bacteria that can cause an infection to form in the urinary tract.

What are residuals? Residuals are compensation paid to performers for use of a theatrical motion picture or television program beyond the use covered by initial compensation. For TV work, residuals begin once a show starts re-airing or is released to video/DVD, pay television, broadcast TV, basic cable, or new media. For film work, residuals begin once the movie appears on video/DVD, basic cable and free or pay television, or new media.
