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

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 Ga-prostate-specific membrane antigen-(PSMA)-11 PET/CT (staging) and 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.
