[Preliminary results of indirect isotopic lymphography with colloidal rhenium marked with Tc 99m in urinary tract pathology].

The authors have carried out a study of a new method for studying the lymphatic system in patients with a neoplastic, urological pathology, by using lymphogammagraphy with radionuclids. It involves the comparative analysis of the lymphatic ganglion chains. This method consists in the subcutaneous injection into the interdigital space of a radionuclid, Colloidal, Rhenium Sulphide, marked with Tc-99m and with external detection by means of a gammacamera and with lymphatic channeling not being necessary.
