Bidirectional-Barbed Sutured Knotless Running Anastomosis <i>v</i> Classic Van Velthoven Suturing in a Model System

It appears from our preliminary work that a bidirectional-barbed suture might improve the vesicourethral anastomosis during a robotic radical prostatectomy. Further investigations should be done to measure the disruptive force necessary to distract these sutures, whether the applied forces of the barbs are adequate for maintaining a watertight seal, and the reproducibility of our results by other surgeons. All of these investigations are in progress in our laboratory.
