Purpose: To report early operative outcomes and assess continence in 100 consecutive patients who underwent Retzius-sparing robotic-assisted laparoscopic radical prostatectomy (RALP). Materials and Methods: This was a prospective, single-center, consecutive case series of 100 and 100 patients undergoing a Retzius-sparing and a conventional RALP, respectively, by a single surgeon between March 2015 and April 2017. Results: Baseline patient characteristics were similar between the two groups. The Retzius-sparing approach required significantly less console time (120.0 minutes vs 144.0 minutes, p < 0.001). There were no differences between intra- and post-operative complication rates, and hospital length of stay was similar in the two groups. Incidence of positive surgical margins was nonsignificantly different between the two groups, with 17% and 13% of pT2 patients and 49% and 48% of pT3 patients in the Retzius-sparing and conventional groups, respectively. Patients in the Retzius-sparing group had significantly superior rates of achieving post-operative urinary continence (log-rank test: p < 0.001), with 20% of patients continent within the first month, compared with 8% of patients in the conventional group. The mean number of pads per day needed at 3, 6, 9, and 12 months post-operatively was also significantly lower in the Retzius-sparing group. Conclusions: Retzius-sparing RALP requires shorter console time, is oncologically safe, and leads to significantly superior continence outcomes compared with conventional RALP.
