We successfully conducted the cystoplasty by regeneration^<1)> on 2 cases of tuberculous contracted bladder by means of a Novectane-sptayed gelatin sponge bladder which was devised and developed by Tsuji, Orikasa, and other collaborators ^<2),3),26)>. Through the follow-up examination we observed that the gelatin sponge broke into small pieces, fell off, and at the same time stuck to the granulation bladder wall. The stuck gelatin sponges might result in inflammation and calculi, bringing disadvantageous factors for regeneration of the bladder. Furthermore, the fragility of the gelatin sponge itself made the delicate process of operation difficult. In our view, an ideal material for regeneration of the bladder is that which makes easy operation possible, does not absorb or stick to the granulation bladder, and falls off completely from the granulation wall after a certain Period following the completion of the bladder. As shown in Figs. 1, A) and B), we have made artificial bladders with Novectane-sprayed thin papers (Japanese paper or tissue paper). As thin paper is used, any form of a paper bladder can be made by cutting and sticking together according to the operator's intension.
