This study shows that using a distal ureter segment, based on a vascular pedicle, is a viable option for urethral reconstruction in patients with congenital malformations. This technique achieved continence in most patients, offering a new reconstructive possibility.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Reconstructive Surgery

Background:

  • Congenital urethral malformations present significant reconstructive challenges.
  • Existing surgical techniques for urethral replacement have limitations.
  • Novel approaches are needed for successful urethral reconstruction.

Observation:

  • Eight patients with complex congenital urethral anomalies underwent urethral replacement using a distal ureter segment.
  • The ureteral segment was vascularized by a pedicle from the internal iliac artery.
  • Continence was achieved through reimplantation into various urinary reservoirs.

Findings:

  • All distal ureter segments remained viable post-operatively.
  • Seven out of eight patients achieved urinary continence.

  • Functional outcomes included normal voiding or intermittent catheterization.

    • Implications:

    • Distal ureter segments are a promising option for proximal or total urethral reconstruction.
    • This technique offers a viable solution for complex congenital urethral defects.
    • Further research can explore long-term outcomes and expand indications.
