Orchofuniculectomy with simultaneous laparoscopic biopsy of the sentinel lymph node using indocyanine green dye with/without methylene blue dye.
Study participants will undergo orchofuniculectomy through an inguinal or laparoscopic approach. After completion of the orchofuniculectomy, indocyanine green (ICG) dye with or without methylene blue dye will be injected into the spermatic cord stump. Next step is detection with a gamma detector the sentinel lymph nodes and follow removing of one or more (up to 4) lymph nodes during laparoscopy. These lymph nodes will be sent for histological examination.
Radiopharmaceutical administration (Technetium/methylene blue)
24 hours before surgery, a radiotracer (RP) will be injected into the spermatic cord followed by SPECT to identify the regional sentinel lymph node(s).
