Summary

Deterioration of bladder augmentation can occur due to blood supply issues or bowel contractions. Re-augmentation using bowel segments is effective for restoring bladder function and continence when conservative treatments fail.

Area of Science:

  • Urology
  • Paediatric Surgery
  • Gastroenterology

Background:

  • Bladder augmentation is a surgical procedure to enlarge the bladder.
  • Deterioration of augmentation can lead to decreased bladder capacity and increased pressure.
  • Identifying causes and effective treatments for augmentation failure is crucial.

Purpose of the Study:

  • To investigate the causes of bladder augmentation failure.
  • To evaluate the efficacy of re-augmentation in pediatric patients.

Main Methods:

  • Retrospective analysis of 136 bladder augmentations (1988-2004).
  • Detailed evaluation of 5 patients requiring re-augmentation after initial colocystoplasty or gastrocystoplasty.
  • Clinical data and urodynamic studies were assessed before and after re-augmentation.

Main Results:

  • Re-augmentation was performed 2-7 years post-initial augmentation.
  • Anticholinergic therapy was ineffective in improving bladder parameters.
  • Re-augmentation with ileal or sigmoid segments resulted in continence and improved urodynamics in all 5 patients.

Conclusions:

  • Causes of failure include impaired blood supply or bowel mass contractions.
  • Ileocystoplasty is recommended as the primary augmentation choice.
  • Re-augmentation is a viable treatment for failed augmentations; regular urodynamic monitoring is essential.
