Late follow up of autoaugmentation omentocystoplasty in a sheep model.
Four male sheep were studied 12 months after an autoaugmentation omentocystoplasty (AAOC). The omentum was lined with urothelium, but continued inflammation and/or fibrosis were seen within the subepithelial tissues associated with a failure to achieve enlargement of the bladder when compared with a control group of six animals. The median compliance value was 5.9 mL/cm H2O for the AAOC animals and 9.8 mL/cm H2O for the control group, indicating that no improvement in bladder dynamic function had been achieved with the AAOC in sheep, and no significant improvement had occurred with time when the results were compared with those seen 6 months earlier.
