There were 36 patients with testicular tumors who underwent abdominal staging by ultrasonography, computed tomography or both before removal and pathologic examination of the retroperitoneal lymph nodes. Results showed that ultrasonography and computed tomography are accurate in predicting retroperitoneal metastases in more than 80 per cent 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 found in patients with borderline enlargement of the nodes (1 to 1.5 cm). Either computed abdominal tomography or abdominal ultrasonography is recommended for pre-treatment staging of testicular tumors.
有36例睾丸肿瘤患者在切除睾丸及对腹膜后淋巴结进行病理检查之前，通过超声、计算机断层扫描或两者联合进行腹部分期。结果显示，超声和计算机断层扫描在超过80%的患者中能准确预测腹膜后转移，尽管计算机断层扫描更准确、更具特异性。两种方法均出现1例假阴性结果，该患者存在镜下（病理IIA期）腹膜后病变。两种技术的假阳性结果均出现在淋巴结轻度肿大（1至1.5厘米）的患者中。对于睾丸肿瘤的治疗前分期，推荐使用腹部计算机断层扫描或腹部超声检查。
