Abstract
Patients (36) with testicular tumors underwent abdominal staging by ultrasonography, computed tomography or both before removal and pathologic examination of the retroperitoneal lymph nodes. Ultrasonography and computed tomography are accurate in predicting retroperitoneal metastases in more than 80% of the patients, although computed tomography is more accurate and specific. The 1 falsely negative result with both methods occurred in a patient with microscopic (pathologic stage IIA) retroperitoneal disease. The falsely positive results with either technique were in patients with borderline enlargement of the nodes (1-1.5 cm). Either computed abdominal tomography or abdominal ultrasonography is recommended for pretreatment staging of testicular tumors.
