Single-Port Robotic Urological Surgery Using Purpose-Built Single-Port Surgical System: Single-Institutional Experience With the First 100 Cases.

Objectives: To present a comprehensive report regarding our experience with single-port robotic surgery in our first 100 consecutive patients. We describe the diversity of procedures that can be performed with this platform as well as the challenges and complications we had with the application of this novel technology.

Methods: Between September 2018 and August 2019, data on 100 patients who underwent single-port robotic surgery were consecutively collected. Preoperative, intraoperative and early postoperative outcomes after various urologic procedures were recorded and analyzed.

Results: During the study period, 100 patients (age [range] 35-84 years; 88 [88%] Male) underwent various single-port robotic surgeries for different indications (Retroperitoneal [n = 14], Pelvic surgeries [n = 86]). Transperitoneal (n = 37), extraperitoneal (n = 53) and transvesical (n = 10) approaches have been used to access the target organs. Of these procedures, 73 (73%) were for different oncological indications: Radical prostatectomy (n = 60), Partial nephrectomy (n = 6), Retroperitoneal lymph node dissection (n = 1) and Radical cystectomy with intracorporeal diversion (n = 6). Surgery was successfully completed in all but 1 patient, in whom the surgery was converted to open surgery due to dense adhesions and failure to progress. Grades II-III postoperative complications were detected in (n = 9) patients.

Conclusion: The purpose-built single-port robotic platform can be safely incorporated into the minimally invasive armamentarium. A wide range of pelvic and retroperitoneal urological procedures can be done with different approaches using this platform. Randomized trials with adequate sample size and postoperative follow up period is advisable for further evaluation of the outcomes and to determine the added value of this emerging technology.
