Oxybutynin has a proved role in correcting uninhibited detrusor contractions in the intact and the bowel augmented bladder. Beneficial responses to oxybutynin have also been noted after gastrocystoplasty. It has been questioned whether this response reflects a selective effect on the bladder segment or whether there is an additional effect on the gastric patch musculature. We report a case of improved function of a previously poorly complaint gastric neobladder caused by oxybutynin, thereby demonstrating a direct action on gastric smooth muscle.

Oxybutynin improves function of gastric neobladders by directly acting on gastric smooth muscle, demonstrating its potential as a bladder reconstruction treatment.

Oxybutynin administration diminishes the high gastric muscular tone associated with bladder reconstruction.
