[Therapy of urethral stricture using free transplants]

Area of Science:

• Urology
• Surgical Reconstruction

Background:

• Anterior urethral stricture disease presents complex challenges in treatment.
• Onlay patch grafting offers a reconstructive option for urethral repair.

Purpose of the Study:

• To evaluate the efficacy of single-stage urethroplasty using penile skin or buccal mucosa grafts.
• To assess the impact of a two-team approach on operative time for buccal mucosa grafts.

Main Methods:

• Single-stage urethroplasty with onlay patch grafts (penile skin or buccal mucosa).
• Implementation of a two-team approach for buccal mucosa graft harvesting and urethroplasty.
• Excision of focal stenosis and combination with other tissue transfer techniques for complex cases.

Main Results:

• Onlay patch grafts are effective for complex anterior urethral stricture.
• The two-team approach significantly reduces operative time when using buccal mucosa.
• Excellent results are achievable for refractory bulbar strictures with graft substitution.

Conclusions:

• Single-stage urethroplasty with onlay grafts is a viable and effective treatment for anterior urethral strictures.
• Buccal mucosa grafts, particularly with a two-team approach, offer an efficient method for urethral reconstruction.
• Graft techniques provide successful outcomes for complex and refractory urethral strictures.
