Summary
This study evaluates a two-stage urethroplasty technique for anterior urethral strictures. The procedure offers a salvage option, successfully reconstructing urethral length in most patients, though some experience residual urinary symptoms.
Area of Science:
- Urology
- Reconstructive Surgery
- Urethral Stricture Management
Context:
- Anterior urethral strictures pose reconstructive challenges.
- Previous one-stage urethroplasty attempts may fail.
- Schreiter's 1984 technique offers a two-stage approach using pedicle skin flaps.
Purpose:
- To present the technique and outcomes of Schreiter's 2-stage mesh-graft urethroplasty.
- To evaluate its efficacy in treating extensive anterior urethral strictures.
Summary:
- Eleven patients with anterior urethral strictures (mean length 7.7 cm) underwent the two-stage urethroplasty.
- After a mean follow-up of 3.5 years, 90% achieved satisfactory results with no recurrence.
- One case failed due to flap size limitations; persistent nocturia and residual urine were noted in some successful cases.
Impact:
- This technique serves as a valuable salvage option for complex urethral strictures.
- It enables the reconstruction of a functional urethral lumen using well-vascularized tissue.
- The method avoids hair follicle issues and allows for staged procedures within a short interval.
