Efficacy of educational stepwise robot‐assisted radical prostatectomy procedure for urology residents

Objective To evaluate the effectiveness of an educational stepwise robot‐assisted radical prostatectomy (RARP) procedure for urology residents. Methods We performed a detailed evaluation of 42 RARP procedures performed by a single urology resident from July 2019 to February 2022. The RARP procedures were divided into the following nine steps: (1) bladder dissection, (2) endopelvic fascia dissection, (3) bladder neck dissection, (4) seminal vesicle dissection, (5) Denonvilliers' fascia dissection, (6) dorsal vascular complex ligation, (7) dissection of the prostatic apex, (8) posterior anastomosis, and (9) urethro‐vesical anastomosis. The procedures were further subcategorized as anatomical understanding, spatial recognition, and technical skills for evaluation of resident training. The surgeries were divided into first and second halves, and patient characteristics and operative outcomes were statistically analyzed. The operative time of each of the nine steps and the reasons for proctor intervention were compared. Results Among 42 patients, there were no significant differences in operative outcomes between the two groups. The median operative time was 169 min (164 vs. 179 min, p = .12), and the median console time was 128 min (127 vs. 130 min, p = .74). Although there were no significant differences in the time of the nine steps, the resident significantly overcame (7) dissection of the prostatic apex and (8) posterior anastomosis based on the evaluation of the proctored reasons for intervention. Conclusions Urology residents can safely perform and efficiently learn RARP with this stepwise educational system. This educational stepwise RARP procedure can effectively help residents to develop their skills.
