Bladder exstrophy and anterior pelvic osteotomy.
Between August 1988 and December 1991, 36 children with bladder exstrophy underwent surgery for primary bladder reconstruction. Each child was either untreated or had already been treated unsuccessfully. The operative technique involved bilateral osteotomy of the superior ramus of the pubic bone. In infants the cartilaginous ischiopubic junction, acting as an articulation, allowed symphyseal approximation, while in older children this was achieved by fracture of the inferior ramus of the pubic bone. The bladder was either closed or, in most cases, the exstrophic bladder plate was inserted deep into the pelvis, allowing subsequent epithelialisation of the bladder and further formation and growth. Follow-up up for 3.5 years showed bladder capacities of 40 to 150 ml. Some patients underwent an additional augmentation enterocystoplasty. Primary bladder reconstruction remained uncompromised in 7 patients who developed moderate (and 1 complete) rediastasis of the pubic bones. All exstrophic bladders are reconstructible, particularly in older children.
