Abstract
Our objective was to determine whether or not male reproductive microsurgery is adaptable to current robotic technology. We devised a model vas deferens system using rat vasa deferentia and completed vasal anastomosis with full-thickness and mucosal robotically placed, Sharpoint 10-0 bicurve nylon sutures. Experienced and inexperienced microsurgeons performed separate anastomoses. Both groups of microsurgeons completed anastomoses with accuracy and enhanced comfort. The robotic graspers had the dexterity to delicately handle the 10–0 sutures and needles. We conclude that through our model vas deferens system, we demonstrated the feasibility of applying robotic technology to male reproductive microsurgery. This pilot study reveals some advantages of the robot and suggests future use of this system in a new urological application domain.
