Purpose:
We determined the clinical applicability, safety and efficacy of endoscopically injected glutaraldehyde cross-linked collagen for the treatment of efferent limb incompetence in the incontinent Indiana urinary reservoir.
Materials And Methods:
Six patients were diagnosed with incompetence of the efferent limb of the Indiana reservoir by video urodynamics. Glutaraldehyde cross-linked collagen was injected through the efferent limb at the level of the ileocecal valve. Outcome was assessed by evaluation of dryness and pouchograms.
Results:
With a mean followup time of 26 months (range 6 to 36) after the last injection 5 of the 6 patients were cured. The remaining patient, although improved, had a small capacity and subsequently underwent ileal patch augmentation. No patient failed to improve. The mean volume of collagen was 16 ml. (range, 5 to 26). Reservoir volume increased from 150 to 400 ml.
Conclusions:
The use of glutaraldehyde cross-linked collagen in the treatment of the incontinent Indiana reservoir is safe and effective.
