title: [The accuracy of lymphography in patients with malignant testicular tumours (author's transl)].
abstract: In 33 patients with malignant teratoid testicular tumours, the retro-peritoneal lymph nodes were surgically removed after lymphograms had been carried out. Histological examination of the lymph nodes showed retroperitoneal metastases in 42% (14 out of 33). In 25 of the 33 patients, there was agreement between lymphography and histology; diagnostic accuracy of lymphography was about 76%. In the presence of positive findings, accuracy was 87%.5%, for negative findings it was 72%. The more frequent false negative findings are due to anatomically determined failure of contrast filling of aortic lymph nodes; the less common false positive findings are produced by involution of lymph nodes.
