@thebrainmaze: Using the Stomach to Enlarge the Bladder - Gastrocystoplasty is a surgical procedure used to enlarge a bladder that is too small or stiff to store urine properly. Surgeons separate a small section of the stomach while preserving its blood supply and attach it to the opened bladder as a flexible patch. This increases bladder capacity and can reduce internal pressure, allowing it to hold more urine.
