Long life expectancy after augmentation cystoplasty increases the importance of late complications of augmentation cystoplasty. Many complications are related to the mucosa of the intestinal flap used for augmentation cystoplasty. We compared a new prefabricated enterocystoplasty flap with the classic techniques of enterocystoplasty using seromuscular flaps. For prefabrication the seromuscular flap was partially grafted with uro-epithelium before augmentation cystoplasty.
