Seromuscular Enterocystoplasty in Dogs

Abstract

An experimental canine model was developed to evaluate the possibility of using seromuscular segments of intestine for bladder augmentation. Of the 10 dogs 5 had bladder augmentations with seromuscular segments of sigmoid and 5 with seromuscular segments of ileum. After 8 weeks we observed that the seromuscular segment was viable and covered with urothelium but intense shrinkage had occurred. Because of the many theoretical advantages of performing bladder augmentation with intestinal segments free of mucosa, we believe that further investigation to elucidate the possible cause of retraction of the seromuscular segment is needed.
