Abstract:

【Abstract】 Bladder cancer is the most common tumor in urinary system in our country, and easy to recurrence and fast widespread of metastasis. Relative to negative lymph nodes, positive lymph nodes tend to recurrent and metastasize more often and once it happens it′ s much more likely to be fatal. It is significantly instructive for the choice of the treatment strategies that predicts positive or negative lymph nodes precisely. At the moment, the gold standard diagnosis of lymph nodes metastases is pathological re?sult after the surgery. Before the surgery, it′s mainly dependent on imaging with unsatisfactory accuracy. This passage would focus on the diagnostic methods of imaging in metastases in pelvic lymph nodes.
