OBJECTIVES

To present our initial operative experience in which single-port-light endoscopic robot-assisted reconstructive and extirpative urological surgery was performed by one surgeon, using a pig model.

MATERIALS AND METHODS

This pilot study was conducted in male farm pigs to determine the feasibility and safety of single-port, single-surgeon urological surgery. All pigs had a general anaesthetic and were placed in the flank position. A 2-cm umbilical incision was made, through which a single port was placed and pneumoperitoneum obtained. An operative laparoscope was introduced and securely held using a novel low-profile robot under foot and/or voice control. Using articulating instruments, each pig had bilateral reconstructive and extirpative renal surgery. Salient intraoperative and postmortem data were recorded. Results were analysed statistically to determine if outcomes improved with surgeon experience.

RESULTS

Five male farm pigs underwent bilateral partial nephrectomy and bilateral pyeloplasty before a completion bilateral radical nephrectomy. There were no intraoperative complications and there was no need for additional ports to be placed. The mean (range) operative duration for partial nephrectomy, pyeloplasty, and nephrectomy were 120 (100–150), 110 (95–130) and 20 (15–30) min, respectively. The mean (range) estimated blood loss for all procedures was 240 (200–280) mL. The preparation time decreased with increasing number of cases (P = 0.002).

CONCLUSIONS

The combination of a single-port, a robotic endoscope holder and articulated instruments operated by one surgeon is feasible. With a single-port access, the robot allows more room to the surgeon than an assistant.
