Abstract:
Objective To develop and evaluate a porcine model for laparoscopic ureterovesical reimplantation (LUR) training. Methods Ten female pigs with a mean weight of 30 kg were used and the animals were placed on supine position after anesthesia. One 10 mm port and two 5 mm ports were placed after the establishment of pneumoperitoneum. The horn of uterus was used as "ureter". A model simulating the performance of LUR was then established on the mini-pigs. Four trainees per-formed the LUR procedures on the animal models during an advanced laparoscopic urology training course, following the technique criteria exactly used in LUR. The learning curve was analyzed in terms of operation time. Results The porcine model for laparoscopic training was established suc-cessfully and 4 LUR trainings was performed on each porcine. Each trainee performed 10 LURs on the models during the training course. The operation time declined from 170±10 rain initially to 90±4 rain after the training course (P<0.01). At the end of this training, all trainees could accomplish a watertight LUR procedure on the model. Conclusions The establishment of the training model is feasible. The trainees could acquire skills needed to perform LUR in vivo based on this simple model and to develop dexterity and facility in laparoscopic manipulation of needles and sutures as well. The model provides a platform for basic techniques training of the ureteral reconstruction procedures.
