Surgery for detrusor overactivity

Abstract

Intractable detrusor overactivity can result in considerable morbidity and, in the case of neurogenic bladder dysfunction, can put the upper tracts at risk. Once conservative treatments have been exhausted the aim of surgery is to increase functional bladder capacity and decrease the maximal detrusor pressure at this capacity. The mainstay of contemporary therapy has been augmentation cystoplasty; the different techniques and recent literature are reviewed herein. Bladder autoaugmentation is compared and contrasted with augmentation cystoplasty and its role is discussed, as is the less invasive technique of sacral neuromodulation with reference to their role within the range of surgical treatments for detrusor activity.
