This study was retrospectively designed and included 72 patients who underwent robotic radical prostatectomy (RARP) combined with PLND. The inclusion criteria were: (1) prostate cancer with a Prostate Imaging Reporting and Data System version 2.1 (PI-RADS v2.1) category 4 or 5 lesion on MRI, (2) Patients who had clinical records of ICG fluorescence or surgical videos of PLND. The clinical impact of the tPLND-MUI was assessed based on its diagnostic accuracy for identifying nodal metastasis and its potential therapeutic value in achieving complete removal of metastatic lymph nodes. A backup PLND using the super-extended template (sePLND) was performed, and outcomes of tPLND-MUI, limited-PLND (limPLND), extended-PLND (ePLND), and standard-PLND (sPLND) were compared against sePLND. A total of 72 patients were incorporated into the final analysis. tPLND-MUI resulted in a median removal of 29 lymph nodes which were fewer than those of sePLND and ePLND. For detecting at least one lymph node metastasis, sensitivity reached 100% with both ePLND and tPLND-MUI, 95.2% with sPLND, and 71.4% with lim-PLND. The ratios of complete removal of lymph node metastases were 81.0% for ePLND, 66.7% for sPLND, 33.3% for limPLND, and 95.2% for tPLND-MUI. tPLND-MUI may demonstrate excellent therapeutic and diagnostic performance despite the removal of fewer lymph nodes and fewer dissecting regions.

Determining whether an adverse event stems from human error, algorithmic malfunction, or a combination of both remains a critical challenge. Unlike open or laparoscopic surgery where liability is primarily attributed to the operator, robotic surgery involves a complex interaction between the surgeon's console inputs and the manufacturer's technology.
