Aim: The success of Robot Assisted Laparoscopic Prostatectomy (RALP) is mainly due to his relatively short learning curve. Twenty cases are needed to reach a "4 hours-proficiency". However, to achieve optimal functional outcomes such as urinary continence and potency recovery may require more experience. We aim to report the perioperative and early functional outcomes of patients undergoing RALP, after a structured modular training program. Methods: A surgeon with no previous laparoscopic or robotic experience attained a 3 month modular training including: a) e-learning; b) assistance and training to the operating table; c) dry console training; d) step by step in vivo modular training performing 40 surgical steps in increasing difficulty, under the supervision of an experienced mentor. Demographics, intraoperative and postoperative functional outcomes were recorded after his first 120 procedures, considering four groups of 30 cases. Results: All procedures were completed successfully without conversion to open approach. Overall 19 (15%) post operative complications were observed and 84% were graded as minor (Clavien I-II). Overall operative time and console time gradually decreased during the learning curve, with statistical significance in favour of Group 4. The overall continence rate at 1 and 3 months was 74% and 87% respectively with a significant improvement in continence rate throughout the four groups (p = 0.04). Considering those patients submitted to nerve-sparing procedure we found a significant increase in potency recovery over the four groups (p = 0.04) with the higher potency recovery rate up to 80% in the last 30 cases. Conclusions: Optimal perioperative and functional outcomes have been attained since early phase of the learning curve after an intensive structured modular training and less than 100 consecutive procedures seem needed in order to achieve optimal urinary continence and erectile function recovery.KEY WORDS: Training; Robot assisted radical prostatectomy. death in men worldwide (1). Radical prostatectomy (RP) represents the standard surgical treatment for clinically localized prostate cancer (2). Traditionally this procedure was performed with a retropubic open approach retropubic radical prostatectomy (RRP) (3), with the cost of long hospitalization, the need of additional pain medication and significant blood loss. With the aim to reduce morbidity, hospitalization and to improve functional outcomes, minimally invasive approaches including laparoscopic radical prostatectomy (LRP) and robot assisted laparoscopic prostatectomy (RALP) have been increasingly adopted as alternative to open surgery. In the last two decades RALP has gained more popularity and now is a mainstay of treatment for prostate cancer, with functional and oncological outcomes comparable or even better than RRP and LRP (4-6). One of the main reason for the great diffusion of RALP is the short learning curve: contrarily to LRP, where the learning curve is very steep, those surgeons approaching to RALP were able to per...
