[Radical lymphadenectomy in non-seminomatous testis tumors using radionuclide detector (author's transl)]

This paper presents first experiences with a new method of bilateral retroperitoneal lymph node dissection in cases of nonseminomatous testis tumors: lymph node-bearing tissue - labeled by conventional lymphoscintigraphy - is intraoperatively directly detected by means of a semiconductor and then removed. In our experience this nuclide detector-directed lymph node dissection seems to be a remarkable improvement of retroperitoneal lymph node dissection because of higher effectiveness, more careful surgical technique and shortened time of operation.
