Muscular sac that acts as a reservoir for urine


 Urine is carried down from the kidneys to the bladder by the ureters


 The bladder empties the urine through the urethra


 Transitional cells line the inner surface of the bladder--this lining begins in the kidneys    and extends through the urinary tract



 Bladder cancer is the most frequent cancer in the urinary tract three times as    frequently as women


 Bladder cancer is quite common for those in their 50s, 60s, and older and affects men



 Patients with low grade superficial cancer have a five-year survival rate of over 70%    following TUR (transurethral resection)



 Patients with more invasive disease have a lower life expectancy
