Long-term Survival of Bladder Augmentation is Influenced by its Shape and Mucosal Lining

Abstract

Bladder augmentation in the UK has been largely by enterocystoplasty or ureterocystoplasty (UC). Ileocystoplasty can be simple patch placement (SPP), or formation of an ileal cup (IC). Urothelium is the “right” mucosa, whereas intestinal mucosa exhibits absorption, mucus production, malignancy. On videourodynamics it can be shown that SPP fills with a poor conformation (irregular shape), while IC was good, and UC adequate.Our aim was to measure the long-term outcomes of augmentation, comparing UC (“right” mucosa and adequate conformation), to SPP (“wrong” mucosa and poor conformation) to IC (“wrong mucosa” and good conformation).
