Methods: This was a prospective, single-center, consecutive case series of 100 and 100 patients undergoing a RS-RALRP and RALRP, 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 vs. 144.0 mins, p<0.001). There were no differences in intra- or post-operative complication rates, and hospital length of stay was similar in the two groups. 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 to 8% of patients in the conventional group. Mean number of pads per day needed at three, six, nine, and 12 months post-operatively was also significantly lower in the Retzius-sparing group. Incidence of positive surgical margins was similar among both groups. Similarly, there were no differences in rates of biochemical failure at three and six months post-operatively.
Conclusion: The authors conclude that RS-RALRP requires shorter console time, is oncologically safe, and leads to significantly superior continence outcomes compared to conventional RALRP.
