摘要

Robotic surgical systems have revolutionized minimally invasive procedures, offering enhanced three-dimensional visualization, high precision, and stable operation, particularly beneficial for radical prostatectomy. However, high costs have hindered the adoption of robot-assisted radical prostatectomy (RARP) in grassroots hospitals in China. This retrospective study aimed to evaluate the efficacy and safety of the EDGE Surgical Robotic System in performing RARP. A total of 129 patients who underwent RARP at our center between November 2023 and March 2025 were analyzed, with outcomes assessed including port placement to docking time, operative time, estimated blood loss, complications, pathological results, safety indicators, length of hospital stay, catheterization duration, postoperative PSA level, and early urinary continence recovery rate. All surgeries were completed successfully without conversion to laparoscopic or open procedures, with a mean setup time of 36.9 min, operative time of 176.3 min, and estimated blood loss of 128.1 mL. The positive surgical margin (PSM) rate was documented at 31.0%, with an average hospital stay of seven days and catheterization duration of 15.4 days. Importantly, no safety incidents were reported, and the average total cost of hospitalization and operative cost was CNY ¥59854.8 (USD $8287.8) and ¥36,249.2 (USD $5,019.26), respectively, indicating a cost-effective approach. While the study’s retrospective design is a limitation, the findings provide preliminary evidence that the EDGE Surgical Robotic System is a safe and economically viable alternative for RARP, paving the way for broader implementation in similar healthcare settings.
