ABSTRACT
Objective To investigate the relationship between tumor location and the risk of developing bladder cancer in pafients treated by nephroureterectomy(NU)for upper urinary tract transitional cell carcinoma(UUT-TCC).Methods The clinical data of 168 UUT-TCC patients who underwent NU were reviewed.Univariate and multivariate analysis were carried out to determine the risk factors for intravesical recurrence after NU.Results The recurrence-free survival rate at 1,3 and 5 years after NU were 88%, 76%and 63%.All patients were followed up for a median period of 45(12-107)months During this period, a total of 49 patients developed bladder tamors after surgery,of which 28 cases were renal pelvic carcinoma, 2 cases were rniddle ureter carcinoma and 19 cases were distal ureter carcinoma.The recurrence-free survival of renal pelvic carcinoma and ureter carcinoma had no significant difference by Log-Rank test(P>0.05).On multivariate analysis,only locating in distal ureter carcinoma was the independent risk predictor for intravesical recurrence after NU (P<0.01).Conclusion Pafients with UUT-TCC at distal ureter carry a higher risk for intraeesieal recunerrce after NU than those with TCC at other location of upper urinary tract.
