Laparoscopic computer-assisted pyeloplasty: the results of experimental surgery in pigs.

Abstract

To evaluate the experimental feasibility of laparoscopic computer-assisted pyeloplasty for pelvi-ureteric junction obstruction. Fourteen pyeloplasties were undertaken in pigs using a laparoscopic transperitoneal approach and the robotic surgical system (da Vinci, Intuitive Surgical Inc., Sunnyvale, CA, USA). The robotic surgical system provides real-time three-dimensional stereoscopic vision. Manipulating the intracorporeal endo-wristed instruments from a remote console allows laparoscopic manoeuvres that are as easy as those during open surgery. Surgeons with no particular experience in laparoscopic surgery could learn complex surgery easily and quickly. This technique provides faster training and the possibility of undertaking complex laparoscopic procedures, especially reconstructive, with less fatigue for the surgeon.
