Introduction: Although robot-assisted radical prostatectomy (RARP) has become a standard treatment modality in patients with prostate cancer (PCa), RARP is a complicated and difficult surgical procedure due to the risk of serious surgery-related complications. This study aimed to evaluate the validation of a standardized training system for RARP in patients with PCa at a single institute.
Material and methods: We retrospectively reviewed the clinical and pathological records of 155 patients with PCa who underwent RARP at Gifu University between August 2018 and April 2021. We developed an institutional program for new surgeons based on the separation of the RARP procedure into six checkpoints. The primary endpoints were surgical outcomes and perioperative complications among three groups (expert, trainer, and novice surgeon groups).
Results: The console time was significantly longer in the novice surgeon group than in the other groups. Regarding bladder neck dissection, ligation of lateral pedicles, and vesicourethral anastomosis, the operative time was significantly shorter in the expert group than in the other groups. Surgery-related complications occurred in 15 patients (9.7%).
Conclusions: Our training system for RARP might help reduce the influence of the learning curve on surgical outcomes and ensure that the surgeries performed at low-volume institutions are safe and effective.
