Our research was conducted to confirm once again whether the RS-RARP fulfills its original purpose. METHODS: A total of 1,863 cases of robot assisted radical prostatectomy was done by a single surgeon (K.H.R.) between October 2005 and May 2018. Conventional and RS-RARP was done in count of 1,150 and 713 cases, respectively. To compare continence outcome between groups, propensity score matching was performed using eight preoperative variables of age, BMI, PSA, biopsy Gleason score, clinical T stage, prostate volumes on TRUS, IPSS and IIEF-5 score. Assessment of continence was done by pad count every one month after the surgery until sixth month and was converted to binary outcome. Generalized estimating equations (GEE) for generalized linear model were used for statistical analysis of continence with joint test of group and time. RESULTS: After propensity score matching, 609 cases in each group were matched for conventional and RS- RARP. Even after propensity score matching, PSA showed statistical difference between groups which probably seems to be the effect of large number cases as few hundreds (12.66±16.97 vs. 14.23±15.27, p=0.027). However, with joint test of group and time, our study revealed that RS-RARP had significantly better continence recovery rate compared to conventional RARP during the whole study period of six month (p=0.006) (Fig. 1). Moreover, even early continence recovery rate at the first month was significantly better with the odds ratio of 5.61 (p<0.001). CONCLUSIONS: In this study, we confirmed once again that RS-RARP can be used as an outstanding surgical procedure to achieve better functional recovery after prostatectomy. Large number of cases, single surgeon experience and propensity score matching gives the strength of this study.
