[Value of transrectal and transvaginal ultrasonic tomography using an electronic linear scanner in staging bladder tumors].

The results of sonographic studies of 48 patients with carcinoma of the urinary bladder are discussed. The value of longitudinal intracavitary sonography for assessment of the local extent of malignant tumors of the bladder was studied. This method is thought to be extremely useful when tumors are localized on the neck, base and front wall of the bladder, whereas transabdominal sonography gives valuable diagnostic information if the lateral and back walls are involved. Combined sonography must be used for assessment of the local extent of carcinoma of the urinary bladder as it is of high accuracy, non-invasive and safe.
