The urinary tract includes the organ system primarily
responsible for cleaning and filtering excess fluid and waste
material from the blood. The urinary system comprises the
kidneys, ureters, bladder, and urethra. The kidneys also
function as glands that produce hormones necessary for building
red blood cells and regulating blood pressure. Many disorders of
the urinary system require clinical care by a physician or other
health care professional. Listed in the directory below are
some, for which we have provided a brief overview. If you cannot
find the information in which you are interested, please visit
