Topic Overview
Key Takeaways
- Ureterocystoplasty achieved 100% stone-free survival at 10 years, outperforming both ileocystoplasty techniques.
- Ileal cup configuration had 95% stone-free survival vs 62% for simple patch, with fewer revision surgeries.
- Bladder augmentation durability depends on both mucosal lining choice and geometric configuration of the graft.
- When ileocystoplasty is indicated, ileal cup formation is preferable to simple patch placement for long-term outcomes.
- Single-institution data (2005-2022) suggests augmentation technique selection significantly impacts stone formation risk.

What are the long-term outcomes of different bladder augmentation techniques? I'm Alex Halpern, a research fellow from Children's National, and this is an article that you should know. Parkinson at all performed a single institution retrospective review from 2005 to 2022 to try and answer this question. They compared outcomes of ureterocystoplasty, ileocystoplasty through ileal cup formation, and ileocystoplasty through simple patch placement. Stone-free survival was 100% at 10 years after ureterocystoplasty, 95% after ileal cup, and 62% after simple patches. Ileal cups had significantly better long-term survival and fewer revision surgeries than simple patches. So it seems like augmentation survival is influenced by choice of mucosa and confirmation, with ileal cups preferable to simple patches when ileocystoplasty is needed.
