Surgeon needs to make practice on models simulating the real organs. The objective of this study is to develop a prototype that could serve for training of laparoscopic pelvis and ureter surgeries. MATERIAL AND METHODS Section of Pediatric Urology having experience on laparoscopy and Department of Animation form Faculty of Fine Arts worked together to develop a prototype. The study was organized with steps including computer modeling, molding and model formation. RESULTS Computer modeling of each steps were designed. In first step, a soft elastic flat plaque was pro- duced from polymers to test suitability for cutting and suturing. In second step, mold was formed and lumen formation was succeeded from the same materials. In third steps, a mold with three d printing and a prototype that could be adaptable for training of laparoscopic pelvis and ureter surgeries was produced. Procedures such as laparoscopic pyeloplasty and ureteroureterostomy were performed on the prototype in training box with success. CONCLUSIONS Synthetic models simulating the real organs may provide a better hands-eye coordination and adaptation to the procedure in laparoscopic training. Well-constructed and chip training models are needed for laparoscopic reconstructive pelvis and ureter surgery teaching in pediatric urology. 14:15–14:18 S1-9 (PP) HYDROGEL SCAFFOLDS FOR DETRUSOR REGENERATION IN RATS AFTER PARTIAL DETRUSORECTOMY Jakub SMOLAR  1 , Daniel EBERLI  1 , Rita GOBET  2 and Maya HORST  2 1) University Hospital Zurich, Urology, Schlieren-Zurich, SWITZERLAND - 2) University Children's Hospital Zurich, Urology, Zurich, SWITZERLAND PURPOSE The use of intestinal tissue as a gold standard for bladder repair in children suffering from end-stage bladder disease is associated with significant long-term complications. Thus, there is a strong clini- cal need for alternative sources of stable and reliable bladder tissue. Our study aims to bioengineer functional detrusor muscle using cells in hydrogel scaffolds.
