Abstract: Purpose: Postoperative recovery of urinary continence has a great impact on quality of life for patients undergoing robot-assisted radical prostatectomy (RARP). A variety of surgical techniques including reconstruction of the periurethral structure have been introduced, and yet there are no effective methods that promote early urinary continence recovery after surgery. We hypothesized that the preservation of pelvic floor muscle structure could be responsible for early recovery of urinary continence after surgery. Methods: A total of 94 consecutive patients who underwent RARP at our hospital were enrolled in this study. Operative video records were reviewed and the severity of pelvic floor muscle injury was classified according to the scoring system that we devised in this study. Briefly, damage of pelvic floor muscles was classified into 4 categories; intact, fascial injury, unilateral muscle injury, and bilateral muscle injury. The volume of urinary incontinence was measured for 2 days after removal of the urethral catheter, and the incontinence ratio (amount of incontinence/total volume of urine per day) was calculated. Predictive factors for immediate incontinence after catheter removal were identified by multivariate regression analysis. Results: The severity of puboperineal muscle injury was significantly associated with the early incontinence ratio after catheter removal (p
