  • Title: [Nonbulky nonseminomas: N-staging value of image-producing study procedures with reference to possible surveillance management].
    Author: Tradowsky M, Bähren W, Egghart G, Altwein JE.
    Journal: Urologe A; 1986 May; 25(3):160-3. PubMed ID: 3016966.
    Abstract:
    In a retrospective study 72 patients with non-bulky nonseminomas were investigated in order to determine the value of computed tomography, sonography and lymphography in the detection of lymph node metastases. The diagnostic results were compared with the histological findings of the retroperitoneal lymph node dissection. In our evaluation computed tomography (n = 48) had an accuracy of 0.77, a sensitivity of 0.62 and a specificity of 0.89; sonography (n = 40) had an accuracy of 0.66, a sensitivity of 0.47 and a specificity of 0.81; lymphography (n = 54) had an accuracy of 0.56, a sensitivity of 0.59 and a specificity of 0.53. Our own results were compared with the results published elsewhere.
