Summary

Classic bladder exstrophy closure without osteotomy or immobilization has a high failure rate. These findings highlight the importance of osteotomy and immobilization for successful bladder exstrophy repair.

Area of Science:

  • Pediatric Urology
  • Reconstructive Surgery

Background:

  • Classic bladder exstrophy (CBE) is a complex congenital anomaly requiring surgical correction.
  • Historically, surgical techniques for CBE closure have evolved, with varying approaches to pelvic stabilization.

Purpose of the Study:

  • To review the outcomes of classic bladder exstrophy closure performed without osteotomy or lower extremity/pelvic immobilization.
  • To evaluate the impact of these specific surgical omissions on closure success and patient continence.

Main Methods:

  • Retrospective review of a prospectively maintained database of 1487 patients with exstrophy-epispadias complex.
  • Identification of 56 closure events in 47 unique patients with CBE who underwent closure without osteotomy or immobilization.
  • Analysis of closure success rates, failure causes, and functional outcomes including social and spontaneous voided continence.

Main Results:

  • A high failure rate of 80.4% (45/56) was observed for CBE closures performed without osteotomy or immobilization.
  • Primary closure failure occurred in 83.7% of cases, and secondary closure failure in 69.2%.
  • While 78.7% achieved social continence, only 17.0% achieved spontaneous voided continence, with continent catheterizable channels being the most common method of voiding.

Conclusions:

  • The results underscore the critical role of osteotomy and postoperative immobilization in achieving successful primary and secondary exstrophy closures.
  • These historical findings remain relevant for contemporary surgeons managing classic bladder exstrophy.
  • The omission of osteotomy and immobilization is associated with significantly higher failure rates and lower rates of spontaneous voided continence.
