Augmentation ureterocystoplasty in bladder exstrophy: 5-year follow-up in two cases

To report two cases of bladder exstrophy managed successfully by augmentation ureterocystoplasty (UCP) together with bladder neck surgery and continent diversion.

Two boys, age 5 and 1 years respectively, had augmentation UCP. The left refluxing megaureter was used in the first case together with bladder neck reconstruction. In the second patient, bilateral obstructed magaureters were used in tandem together with bladder neck division. Both patients had appendicovesicostomy according to Mitrofanoff.

In follow-up for over 5 years, both patients are continent with improved upper urinary tracts and normal or stable renal function. They are managed by clean intermittent catheterization (CIC) via the continent stoma with bladder capacities of 220 cc and 150 cc, respectively. Cystogram showed no vesicoureteric reflux (VUR). The procedures were considered to be successful although one patient was on oxybutinin because urodynamics showed high intravesical pressures.

Augmentation UCP should be considered in patients with bladder exstrophy when a suitable megaureter is available. This may be combined with simultaneous bladder neck reconstruction together with a continent diversion.
