Abstract
Purpose
: To create a simple model for training in the complex technique of laparoscopic vesicourethral anastomosis after radical prostatectomy.
Materials and Methods
: A model simulating the performance of a laparoscopic running urethrovesical anastomosis was fashioned using skin of a supermarket chicken set in a laparoscopic training box. A circular continuous anastomosis was performed, following exactly the technique we use in vivo for performing a vesicourethral anastomosis after laparoscopic radical prostatectomy. Details regarding the use of the right or the left needle holder, needle positioning, precise stitch position, and use of forehand or backhand stitch were strictly respected in order to reproduce the continous stitch currently done in vivo in our department. The learning curve was analyzed in terms of the time necessary to perform the task and the quality of the anastomosis.
Results
: The model was created and used by the junior authors during their year of fellowship in advanced laparoscopic urology. The authors had no previous experience with hands-on laparoscopic suturing but have assisted in a great number of laparoscopic radical prostatectomies. The time required for performing the anastomosis on the model declined from 75 minutes initially to 20 minutes after the trainees had performed 20 anastomoses each. After this training, it was possible to create a watertight running laparoscopic vesicourethral anastomosis in patients in a mean time of 40 minutes (range 30-55 minutes).
Conclusion
: This simple model allows the trainee in laparoscopic urology to acquire the skills necessary to perform a laparoscopic vesicourethral anastomosis, one of the most complex steps in laparoscopic radical prostatectomy, as well as to develop dexterity and facility in laparoscopic manipulation of needles, sutures, and fragile tissues.
