Lymphography in the evaluation of urinary bladder carcinoma.
Lymphography was performed in 41 patients with bladder carcinoma. The lymphographic findings were correlated to the clinical and histological staging and the pre-operative grading. Twenty-seven patients were operated upon. The findings of lymphography were compared with the findings at operation, and the pathological examination of the removed lymph nodes. The lymphographic diagnosis was proved to be correct in 77.7% of the patients. There were two false positive lymphographies, and one false negative. Lymphography in groups T3 or T4 yielded a high diagnostic accuracy.
