Bladder autoaugmentation: partial detrusor excision to augment the bladder without use of bowel.

A surgical technique of partial detrusorectomy (autoaugmentation) for creation of a diverticular bulge of the dog bladder is described. The method is designed to serve as a bladder augmentation without using bowel. We describe the technique, results with dogs and its clinical application. Partial detrusorectomy appears to function as an autoaugmentation that can be performed reliably in dogs, offers potential advantages over bowel segments, and is a potential alternative to enterocystoplasty in selected patients.
