OBJECTIVE: To describe our initial clinical experience of robotic single-port (RSP) surgery. PATIENTS AND METHODS: The da Vinci S robot (Intuitive, Sunnyvale, CA, USA) was used to perform radical prostatectomy (RP), dismembered pyeloplasty, and radical nephrectomy. A robot 12-mm scope and 5-mm robotic grasper were introduced through a multichannel single port (R-port, Advanced Surgical Concepts, Dublin, Ireland). An additional 5-mm or 8-mm robotic port was introduced through the same umbilical incision (2 cm) alongside the multichannel port and used to introduce robotic instruments. Vesico-urethral anastomosis and pelvi-ureteric anastomosis were successfully performed robotically using running intracorporeal suturing. RESULTS: All three RSP surgeries were performed through the single incision without adding extra umbilical ports or 2-mm instruments. For RP, the operative duration was 5 h and the estimated blood loss was 250 mL. The hospital stay was 36 h and the margins of resection were negative. For pyeloplasty, the operative duration was 4.5 h, and the hospital stay was 50 h. Right radical nephrectomy for a 5.5-cm renal cell carcinoma was performed in 2.5 h and the hospital stay was 48 h. The specimen was extracted intact within an entrapment bag through the umbilical incision. There were no intraoperative or postoperative complications. At 1 week after surgery, all patients had minimal pain with a visual analogue score of 0/10. CONCLUSIONS: Technical challenges of single-port surgery that may limit its widespread acceptance can be addressed by using robotic technology. Articulation of robotic instruments may render obsolete the long-held laparoscopic principles of triangulation especially for intracorporeal suturing. We report the initial series of robotic surgery through a single transumbilical incision.
