Augmentation myoperitoneocystoplasty

Abstract

The use of isolated intestinal segments is currently the best method of augmenting bladder capacity. The ability to perform a successful augmentation cystoplasty using nonintestinal tissue would decrease the morbidity of the operation. We studied the use of skeletal muscle-backed parietal peritoneal tissue in augmentation cystoplasty. In the experimental group animals, bladder capacity increased by 67% and urothelial regeneration was observed histologically. Problems with electrolyte abnormalities, urosepsis, or excessive mucous production were not encountered. In conclusion, a myoperitoneal flap may serve as a template for augmentation cystoplasty. Further investigation using this technique is warranted.
