Advances in tissue transfer techniques have improved anterior urethroplasty, with buccal mucosa grafts now favored. Current evidence shows similar success rates for grafts and flaps in treating urethral strictures.

Area of Science:

  • Urology
  • Reconstructive Surgery

Background:

  • Anterior urethroplasty techniques have evolved over 40 years.
  • Etiology of urethral stricture has changed.
  • Free grafts, including buccal mucosa, have resurged in popularity.

Purpose of the Study:

  • To review the evolution of anterior urethroplasty techniques.
  • To compare the outcomes of grafts versus flaps for urethral stricture repair.

Main Methods:

  • Review of historical and current techniques in anterior urethroplasty.
  • Analysis of success rates for free grafts and pedicle flaps.

Main Results:

  • Free grafts, particularly buccal mucosa, are now preferred for many strictures.
  • Overall success rates for grafts (84.3%) and flaps (85.9%) are comparable.

  • Grafting is considered first-line therapy for unresectable strictures.

    • Conclusions:

    • Current evidence does not support a significant outcome advantage for flaps over grafts.
    • Grafting techniques represent a significant advancement in managing urethral strictures.
    • Buccal mucosa grafts are a reliable option in anterior urethroplasty.
