Cystometric properties of ileum and right colon after bladder augmentation, substitution or replacement.
Cystometric studies were performed on 38 patients who had undergone augmentation, substitution or replacement enterocystoplasty. These studies were done to determine the choice of bowel segment to augment or replace the detrusor and the shape in which the bowel segment should be reconstructed. Eleven patients underwent tubular and 10 detubularized right colon cystoplasty, while 10 underwent tubular (Camey bladder) and 7 detubularized ileocystoplasty. Compliance curves were normal in nearly all patients except those who underwent tubular ileocystoplasty. Cystoplasty contractions were more common with tubular cystoplasty. These contractions appeared at a lower bladder capacity and were higher in amplitude in tubular cystoplasty patients. Detubularizing the bowel for bladder reconstruction appears to create a better low pressure capacitor with better compliance and fewer high pressure cystoplasty contractions.
