| Outline of Final Research Achievements |
In this study, we investigated the renovation of the bladder wall using bio absorbable polymer sheet（BAPS）which we developed originally. After having excised the bladder of the pig partially to various size, we transplant BAPS which we trimmed to the same size, and it was evaluated it macroscopically and histologically. As a result, BAPS repaired the defective bladder wall after partially bladder wall excision site. However, there was a problem for the remarkable shrinkage of BAPS in the bladder capacity by a more extensive loss. To avoid this shrinkage, we placed a stent to maintain the shape of the bladder after implantation, and this method was successfully to repair the bladder. It is suggested that this model which use BAPS for the defective tissue should approach the goal of clinical surgical use in future.
