[Radioisotope lymphadenectomy in testicular tumors (author's transl)]

This paper presents a preliminary report of the first eleven patients with testicular cancer who underwent lymphadenectomy assisted by radioisotope techniques with a special designed gamma surgical camera. In cases of only partial carcinomatous infiltration the lymph nodes are well marked with the radioisotope. Additionally colour television gives the surgeon an objective continuous control of the actually dissected lymphatic tissue during all phases of surgery. In our experience the use of radioisotope-techniques and a gamma surgical camera seem to be of great value in improving lymph node extirpation in cases of testicular cancer.
