ABSTRACT

BACKGROUND:

Abdominal and pelvic closure remains a challenge during bladder exstrophy initial repair. We aimed to report on the feasibility and results of a novel technique of bilateral obturator osteotomy.

METHODS:

Retrospective study of prospective collected data of children who underwent single-stage delayed bladder exstrophy closure combined with RSTM (Radical Soft Tissue Mobilization) for BEEC (Bladder Exstrophy Epispadias Complex) by the same team at different institutions between December 2017 and May 2021. When pubic approximation was not feasible at the end of the procedure, bilateral obturator osteotomy was performed through the same approach, consisting in bilateral divisions of the ilio-pubic rami, ischio-pubic rami, obturator membrane, and detachment of the internal obturator muscle. Pubic bone fragments were approximated together on the midline. Immobilization in a thermoformed posterior splint was indicated for 3 weeks. The main outcome criterion was the bladder dehiscence rate at 6 months, assessed by physical inspection. Secondary outcome criteria included neurovascular obturator pedicle injury, analyzed during orthopedic physical examination, wound or bone infections, gait acquisition, reported by parents and evaluated during medical examination, and vascular penile impairment, judged by penile and glans coloration.

RESULTS:

17 children (11 males, 6 females) were included, at a median age of 2 months [1-33]; and representing 29% (17/58) of the children with bladder exstrophy who underwent the same surgical approach during the time of study. There was no postoperative bladder dehiscence with a median follow-up of 34 months [6-47]. No complication was observed. Pelvic X-rays showed bilateral normal ossification process. Neither gait abnormality, nor clinical indication of obturator nerve deficiency was observed during follow-up.

CONCLUSION:

When pubic bones approximation is not possible, bilateral obturator osteotomy is a useful adjunct in bladder exstrophy closure, feasible by the pediatric urologist through the same approach, and not requiring external fixator. LEVEL OF EVIDENCE IV.
