Transrectal ultrasonotomography provides us with information as to the presence, localization and size of a lesion in the urinary bladder with ease, and has become one of the routine diagnostic examinations of bladder tumor in our clinic. A ultrasonographic study of diagnosing the stage of bladder tumors was made on 17 patients. These tumors were histologically examined by transurethral resection or biopsy of tumor, or total cystectomy. Ultrasonographic diagnosis agreed with the histological findings in 11 (64.7%) of 17 patients. Restricted to 8 cases which histological findings were examined by total cystectomy, an accuracy of 77.8% (7 cases) was obtained, and this technique will become more accurate by further ultrasonographic examination of patients with bladder tumor. In addition, this ultrasonotomography is carried out for the follow-up study of chemotherapy and/or radiotherapy of bladder tumor and let us know the effect of these therapies. Because of its non-invasive nature and diagnostic accuracy, transrectal ultrasonotomography should be used widely for the routine examination of bladder tumor.
