Materials and Methods: Robot-assisted radical prostatectomy was done by a single surgeon in 1,863 cases between October 2005 and May 2018 using the conventional and the Retzius sparing technique in 1,150 and 713, respectively. To compare continence outcomes between the groups propensity score matching was performed using 9 preoperative variables, including age, body mass index, prostate specific antigen, biopsy Gleason Grade Group, clinical T stage, prostate volume on transrectal ultrasound, and the I-PSS (International Prostate Symptom Score), I-PSS quality of life score and IIEF-5 (International Index of Erectile Function-5) scores. Continence was assessed by the pad count every month postoperatively until month 6 and was converted to a binary outcome. Results: After propensity score matching 609 cases per group were matched with no significant difference in all 9 variables. The Kaplan-Meier curve analysis revealed that Retzius sparing robot-assisted radical prostatectomy was associated with a significantly better continence recovery rate than conventional robotassisted radical prostatectomy during the 6-month study period (p <0.001). Conclusions: Based on propensity score matching with multiple variables and a large case series, Retzius sparing robot-assisted radical prostatectomy can be a candidate for future robot-assisted radical prostatectomy. It achieves better early continence recovery, a short operative time and early recovery compared to conventional robot-assisted radical prostatectomy. keywords : prostatic neoplasms, prostatectomy, robotic surgical
