摘要
Bladder carcinoma is the most common tumor in the urinary system. In 1996, a sampleinvestigation showed that bladder carcinoma, in which more than 90% was mainly primary bladder transitional cell carcinoma （BTCC）, was one of the ten highest mortality malignant tumors in China. Bladder carcinoma represented 2% of all malignant tumors and has the fifth most common malignancy in men in Europe and North America.
