Summary
Despite generous augmentation with bowel, some bladders demonstrate persistent instability. To determine whether this phenomenon arises in the vesical or intestinal components of the augmented bladder, the cystometrograms of 181 children exhibiting neuropathic bladders were reviewed; 67 that showed evidence of detrusor hyperactivity were selected for comparison with cystometrograms of 33 children in whom enterocystoplasty had been performed. In 19 cases, a within-subject comparison was possible. Five independent variables representing bladder capacity and intrinsic activity were chosen for the study. There was a significant difference in the characteristics of bladder activity between unaugmented and augmented bladders. The results suggest that instability in the augmented bladder is attributable to intestinal rather than detrusor activity.
