The technique of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) and initial experience with it at a single center are provided. The technique is described step-by-step and further illustrated by a video to enhance reproducibility. Early oncological and functional results were evaluated. In total, 77 patients were included with a median follow-up of 11 months (range: 3-21 months). Fifty-one percent of patients had local high-risk or locally advanced prostate cancer. There were no intra-operative complications, and all high-grade complications (2.6%) were related to pelvic lymph node dissection performed concomitant with RS-RARP. Median operation time was 160 min (range: 122-265 min) and median hospital stay was 3 (range: 3-8) days. A positive surgical margin was reported in 42.9%. One-year biochemical recurrence-free survival was 90.1%. After 6 months, all patients were socially continent and after 1 year, 94.3% were fully continent. Of sexually active patients who underwent at least unilateral nerve-sparing, 43.3% were able to have sexual intercourse. This series underlines the surgical safety of performing RS-RARP by a standardized technique and confirms the beneficial effect on the early return of continence. The patient needs to be informed about the risk of a positive surgical margin.
