Initial experience of single-port robot-assisted radical prostatectomy: A single surgeon's experience with technique description.

Background: With the implementation of da Vinci SP robot platform (Intuitive Surgical, Inc., Sunnyvale, CA, USA), we described our initial experience with the da Vinci SP robot platform (Intuitive Surgical, Inc., Sunnyvale, CA, USA) for single-port robotic-assisted radical prostatectomy (SP-RARP). Methods: This retrospective review included 30 consecutive patients with prostate biopsy-confirmed prostate cancer who underwent SP-RARP by a single surgeon between June and November 2020. SP-RARP was performed with a single-incision plus one method, in which the multichannel guide port was inserted directly with an additional assist port. We report our initial experience of perioperative and early functional outcomes. Results: The mean operative time (SD), console time (SD), and blood loss were 142.8 (15.1) min, 109.9 (15.7) min, and 133.0 (72.9) mL, respectively. No intraoperative complications or blood transfusions were reported. Of the 30 patients, 21 (70.0%), 7 (23.3%) and 2 (6.7%) had stage pT2, pT3a and pT3b disease, respectively. Positive surgical margins were reported in 5 of the 30 (16.7%) patients in the final pathology report, including 2 of 21 (9.5%) with stage pT2 and 3 of 9 (33.3%) with ≥ pT3. At 12 weeks after SP-RARP, 80.0% of patients had achieved continence and the potency was 46.7%; 8 of 11 (72.7%) had sexual health inventory for men (SHIM) scores ≥ 17 and 6 of 19 (31.6%) had SHIM scores < 17. Conclusions: The SP platform for radical prostatectomy was technically safe and feasible. After overcoming the technical learning curve, this platform may provide high-quality outcomes comparable to those of multi-port platforms.
