Experiences based on the classification of bladder tumours according to the TNM system

Since 1967 we employ the TNM system of the UICC for the classification of bladder tumours. Cystography, pelvic arteriography and lymphography were carried out for the classification. 393 patients were examined by means of the X-ray methods. 323 patients were classified according to the TNM system. The 'P' stage was stated in 134 patients. This group of patients enabled a control of the pre-therapeutical classification. We found extensive conformity between pre-operative and post-operative diagnoses. The methods of classification tested by us allow an exact diagnosis.
