Upper Urinary Tract Tumors Developing After Bladder Cancer

[Objectives] :TO study upper urinary tract transitional cell cancer(UUT TCC) incidence and characteristics,evaluating diagnosis and treatment of metachronous UUT TCC .[Methods] 422 superficial bladder cancer patients and 215 invasive bladder cancer patients were treated,and developing metachronous UUT TCC'clinc features were analysed. [Results] 16 of 637 patients developed metachronous UUT TCC ,among these were 10 patients in superficial group and 6 patients in invasive group. the incidence of UUT TCC was not statistically significant (p>0.05 ) between superficial group and invasive group, the same result was attained between intermediate risk group and high risk group in superficial bladder cancer, theincidence of UUT TCC were significantly higher in patients at intermediate risk and high risk than in those at low risk (p<0.05 ) [Conclusions]Pathologic stage,the number of tumor,carcinoma in situ were risk factors that developing metachronous UUT TCC after superficial bladder cancer. UUT TCC after treatment of invasive bladder cancer tend to have a relatively poor prognosis.
