Abstract

Bilateral posterior iliac osteotomy is performed in most patients undergoing primary closure of an exstrophic bladder; the aims are to facilitate abdominal-wall closure, prevent postoperative wound dehiscene, and possibly, to achieve better urinary control in older age. A new technique, anterior pelvic osteotomy of the superior pubic ramus, seems to obtain tension-free symphysis approximation safely and quickly. We report our initial experience with this osteotomy. Five neonates, four males and one female from 1 to 4 days old, all underwent closure surgery for bladder exstrophy (BE) and subsequent bilateral osteotomy of the superior pubic ramus (SPRO). Postoperatively, Bryant's traction was applied. Tension-free, complete approximation of the symphysis and uncomplicated healing were achieved in all five cases without palsy of the obturator nerve or postoperative hemorrhage. Follow-up revealed partial rediastasis with a stable anterior pelvic ring. Tension-free closure and immobilization are important factors in both initial and subsequent closure of BE. Several osteotomy techniques are currently in use. SPRO presents numerous advantages, namely, ease and rapidity, minimal blood loss, and no requirement for an extra skin incision or need to turn the patient on the operating table. A certain degree of rediastasis with growth was subsequently observed: although undesirable, this complication is common to all osteotomy techniques. We believe that SPRO is a valid and uncomplicated method to facilitate BE closure.
