Abstract
Purpose
To evaluate the urodynamic changes in patients who have undergone colocystoplasty (CCP), gastrocystoplasty (GCP) and ileocystoplasty (ICP) in a retrospective study. Changes in urinary continence, incidence of pathologic contractions before and after augmentation, alterations of urodynamic parameters were also examined.
Methods
Eighty-four patients were included in the study who underwent bladder augmentation between 1987 and 2017. Group I: 35 patients with CCP. Group II: 18 patients with GCP. Group III: 31 patients with ICP. Cystometry was performed at 3, 6, and every 12 months, then biannually after augmentation. Pre- and postoperative urodynamic changes were analysed statistically.
Results
In Group I, two patients and in Group III, one patient remained incontinent after CCP and ICP. Bladder capacity increased significantly, maximal intra-vesical pressure decreased and compliance improved in all groups (p < 0.001). Postoperative studies showed pathologic contractions in the augmented bladder in half of the patients with GCP, in 43% of patients after CCP and 26% of patients with ICP.
Conclusion
From the urodynamic point of view, ileum is the most adequate option in the long term. Contractions after augmentation might be caused by the remaining peristalsis of the detubularised segment. Further investigations are needed to evaluate pathologic contractions that remained after detubularisation.
