Abstract: Background and Purpose: Bladder dysfunction may lead to urinary incontinence and progressive kidney deterioration. When clinical treatment fails, bladder augmentation is the operation of choice in most cases. The purpose of this study was the standardization of the technique of videolaparoscopic ileocystoplasty in a porcine model and demonstration of a tutor-supervised learning curve. Materials and Methods: The study was conducted on 15 Large-White male pigs (20-25 kg) that underwent ileocystoplasty with 15 cm of distal ileum shaped into a U using extracorporeal technique and laparoscopic ileovesical anastomosis. Operative time, ileovesical anastomosis time, intraoperative complications, and extravasation after anastomosis were evaluated. To assess the learning curve, the animals were divided into three groups of five: group I (operated on in collaboration with a tutor), group II (treated under the supervision of tutor), and group III (without the tutor's collaboration or supervision). Results: Total surgical time and ileovesical anastomosis time revealed significant differences (P < 0.05) between groups I and III (70% reduction) as well as between groups II and III (64% reduction). Conclusions: Laparoscopic ileocystoplasty in pigs is feasible without special laparoscopic material. Ten initial procedures with a tutor's help were important for technique acquisition and mastery. A sharp increase in efficiency occurs between the tenth and fifteenth procedures. These procedures should be executed at least ten times in the presence of the tutor to enable the surgeon to overcome the learning curve.
