The value of sonography and lymphography in the detection of retroperitoneal metastases in testicular tumors.
Lymphography has led to falsely negative or falsely positive diagnoses in 10 to 45 per cent of the cases of testicular tumor metastases reported in the literature. In our comparative study of lymphography and sonography in the preoperative staging of 29 malignant testicular tumors lymphography was accurate in 58.5 per cent of the cases, while sonography had an accuracy rate of 82.5 per cent. Sonography was superior to lymphography in the evaluation of hilar lymph node metastases and their extent, as well as for routine checkups after lymphadenectomy or irradiation.
