[Determination of depth of infiltration of of vesical tumors by intravesical ultrasonic tomography (author's transl)].

A prerequisite for the therapeutic procedure in bladder carcinoma is the determination of the depth of infiltration and extent of the tumor. This is possible by means of intravesical ultrasonic tomography as studies in 19 patients with vesical tumors of different sizes and extent showed. Histologically verified infiltration depths correlated with the intravesical ultrasonic findings in all cases so far. A statement on the percentage accuracy of the sonographic findings is not yet possible because of the small number of cases so far.
