Lymphography in the management of urologic tumors. Radiological-pathological correlation.

Of 59 patients undergoing lymphography as part of staging for urologic tumor (bladder carcinoma, prostate carcinoma, seminomatous and nonseminomatous testicular tumors), histological material was obtained in 38. Lymphography was shown to have a specificity of 95%, a sensitivity of 81%, and an overall accuracy of 89%. When lymph node regions were considered, the specificity was 99.2%, sensitivity 59%, and overall accuracy 91%. Causes of discrepancies between radiography and histology are evaluated and receiver operating characteristic curves are demonstrated.
