Abstract
Experience with the preoperative staging of bladder cancer by bilateral selective hypogastric arteriography had accumulated since 1968. More than 150 patients were studied by selective angiography before radical cystectomy. The latest series of 52 patients (1972-1976) compares to previous experience demonstrating angiographic staging accuracy to detect bladder invasion and occult metastases at a rate exceeding that of clinical staging alone. Arteriographic staging of D lesions, when supplemented with lymphography, approaches 100% accuracy. Falsely negative lymphograms currently are extremely uncommon (1.9%). In several illustrated instances angiographic staging was even more accurate than the pathologic staging of a limited cystectomy specimen. The overall angiographic and lymphangiographic staging accuracy in the most recent series of cystectomy patients was 78.8%. The techniques and reliability of the data are discussed in detail, including the factors that interfere with the exact arteriographic staging of bladder cancer. These factors are more troublesome in early stage lesions. These studies demonstrate the role and value as well as areas of limitation of preoperative arteriography and lymphography in the evaluation of invasive bladder cancer.
