| Abstract: | Our study includes 12 patients. Of these, six had transitional cell carcinoma, three patients with stones and three patients with blood clots. With the use of computed tomography we were able to arrive at a reasonable staging and diagnosis of the filling defects. Computed tomography is not sufficiently sensitive to recognize microscopic invasion. Reactive fibrosis and postobstructive inflammatory changes can mimic tumor invasion on computed tomography, and in such cases staging will not be accurate. |
