[Animal model for training in laparoscopic pyeloplasty].
OBJECTIVE
With the coming of the laparoscopy, multiple surgical techniques have been developed that have revolutionized the urological practice. The laparoscopic pyeloplasty has been one of the techniques most developed. However, there are very few training models that permit the surgeon to decrease the learning curve. An animal model of training for the laparoscopic pyeloplasty technique is described.


METHODS
Eight procedures of laparoscopic pyeloplasty were performed using the animal model (Gallus gallus) in the laparoscopic practice laboratory of the Urology Service of the University Hospital of Caracas. The preparation times of the model and the operation times of each surgeon were compared. The statistical analysis was made calculating the mean operation time, standard deviation, frequencies and percentages. A significant value was considered as p < 0.05.


RESULTS
The laparoscopic pyeloplasty procedure was performed successfully in all of the cases by two surgeons. The preparation time ranged from a maximum of 14 minutes to a minimum of 6 minutes, this being the same for both surgeons in the fourth case. The operation time ranged from a maximum of 65 minutes to a minimum of 43 minutes, observing significant differences when comparing the times individually for each surgeon. Only one case had filtration when comparing the patency of the specimen.


CONCLUSIONS
The animal model of training of laparoscopic pyeloplasty that is described is economical, reproducible, of easy availability and it makes it possible to develop laparoscopic surgical skills and competency necessary for reconstructive surgery and techniques that warrant intracorporeal suture.
