Abstract
Management of the upper urinary tract, especially protection of the upper urinary tract infection is one of the most important problem during treatment of the bladder cancer.
Here we report that obtained from the inspection of vesicoureteral reflux(VUR)of bladder cancer patients as a factor which initiates the upper urinary tract infection. VUR were found in 12 cases (22.6%) out of 53 cases of the bladder cancer. There are no statistical significance between VUR and pyuria, tumor site&tumor grade.
We have treated bladder cancer patients by external irradiation with 6 MeV linear accelerator. In 4 cases out of 5 cases with reflux VUR disappeared after the irradiation. In 7 cases out of 14 cases without reflux VUR were newly found after the irradiation. Contract bladder were found in 3 cases out of these 7 cases.
