Minimal-Invasive Robot-Assisted Image-Guided Resection of Prostate-Specific Membrane Antigen–Positive Lymph Nodes in Recurrent Prostate Cancer

Abstract With the rapid expansion of robot-assisted surgical procedures, the need for robot-compliant image guidance technologies has also increased. Examples hereof are the integrated firefly fluorescence camera, the drop-in ultrasound probe, and the recently introduced DROP-IN gamma probe. Combined with 68 Ga–prostate-specific membrane antigen–(PSMA)–11 PET/CT (staging) and 99m Tc-PSMA-I&S SPECT/CT (preoperative imaging), the latter DROP-IN gamma probe technology recently allowed us to perform the first clinical cases of robot-assisted PSMA-guided salvage surgery of lymphatic metastases.
