[An evaluation of lymphangiography in the diagnosis of nodal metastasis from genitourinary cancer].

From September 1979 to March 1988, lymphangiography was carried out in 187 cases of genito-urinary cancers and the specific features of metastatic lymph-nodes have been summarized. The results showed that the false positive was much lower in bladder, testicular, and prostatic cancers than in penile cancer. In order to enhance visualization of the pelvic, lumbar and kidney-hilar nodes, a combined lymphangiography should be done through both bipedal and funicular routes. A percutaneous FNAB is necessary to minimize the false positive.
