Robotic Perineal Radical Prostatectomy: Initial Experience with the da Vinci Si Robotic System.

Purpose: To investigate the feasibility and surgical technique of robotic perineal radical prostatectomy (RPRP). Materials and Methods: We retrospectively analyzed 6 consecutive patients diagnosed with prostate cancer from December 2018 to May 2019 who underwent RPRP at our center. Perioperative outcomes were recorded for safety and feasibility analysis. Results: Six patients successfully underwent RPRP with no conversion to open procedures. Operative time was 140 (interquartile range [IQR] 123.75–148.75) min, console time was 70 (IQR 62.5–70) min, with an estimated blood loss of 125 (IQR 100–187.5) mL. Patients were discharged 2 days postoperatively (IQR range 1–3) with pelvic drainages removed. The Foley catheter was removed 2 weeks after surgery. Postoperative pathology revealed 5 patients with locally advanced disease (apical margin-positive prostate cancer [pT3a]bNx). Two patients had a positive surgical margin (33.3%). No complications of Clavien grade 3 and above were recorded; 1 patient had a delay in wound-healing of 1 week. Postoperative continence was achieved for 2 patients immediately after Foley catheter removal, 2 recovered 1-month postoperatively, and 1 recovered within 3 months, and 1 still had mild incontinence at the latest follow-up 1-month postoperatively. Conclusion: RPRP is a safe and feasible alternative for the transperitoneal route in selected patients. Further investigation is required to assess its oncological and quality-of-life results.
