Augmentation enterocystoplasty can be done to create a low-pressure reservoir. It is a well-described procedure that is used for congenital and acquired neurogenic bladder dysfunction and reduced capacity bladders secondary to other congenital problems such as posterior urethral valves, exstrophy, and for postinfectious, post-inflammatory, postradiation, and iatrogenic problems. The procedure may be the step before supravesical diversion in selected patients. Renal functional integrity and patient compliance with management such as intermittent catheterization and long-term follow-up are essential features. Concomitant treatment of associated urethral sphincter weakness and the need for an abdominal catheterization access are important considerations. Long-term monitoring of the upper and lower urinary tracts is necessary to identify and treat complications.
